(High School Mystery Club 3)
(Second day of school at Songhwa Girls' High School)
(Hop)
(Jaejae is the first to arrive today too)
What will happen at Songhwa today?
(She immediately goes to her seat)
(Please come soon)
Hello.
(The excited duck of the mystery club is here)
(She is taking something big)
What do you have with you?
I brought the items to decorate our club's room.
It is quite big.
I prepared everything myself.
Why does she have a lot of things?
- Hi. - Hi, Yena.
Why do you have so many things?
(Her eyes are getting bigger)
We decided to decorate our club's room, didn't we?
(Struggling)
Why do you have so many things?
It is just big. Not a lot.
(Peeking first)
(Yena brought decorations that she made herself)
- You made these yourself? - Yes.
(What decorations did Yena bring?)
(BIBI is the third to arrive)
You are wearing glasses today.
Yes. This is for fashion.
There are no lenses.
(BIBI is here)
- Hi. - It's BIBI.
I think she dressed up today.
You look like a student today.
Old style.
- You are wearing a hairpin. - Yes.
You are wearing an ear warmer.
(Staring)
Yena is like a celebrity.
No.
(Showing lots of love for Yena again today)
(The tall one is the fourth to arrive)
Somehow,
I think there will be police today.
(She thinks that something big will happen)
Since we are now in season 3,
I think I know how things go.
(Full of confidence)
If I have to predict something,
journalists will be here in the afternoon.
What do you think of my instinct?
Please check it out later.
Let's see if I was right or wrong.
Instinct!
Hello.
(Jiyoon, the deduction queen, is here)
You are using a pretty pair of glasses today.
Yes.
People might think that this is for fashion,
but these are magnifying glasses.
You start aging at this age.
(Everybody has arrived)
(They are interested and focused on Jiyoon)
(Powerful energy from the leopard print)
Let's put our fears behind and go for it.
But you look somewhat scared.
(She is tough outside but soft-hearted inside)
(Time to show the decorations)
- What is that? - This is Foxy Jae.
(Foxy Jae since it is a fox that looks like Jaejae)
(So cute)
All of us have one each.
We have Meowy Bi and Foxy Jae.
(Jiyoon / Doyoun / Jaejae / BIBI / Yena)
(100 percent in sync)
I brought this.
This marble changes its color depending on the weather.
If the weather is bright, the liquid will be clear.
If it rains, it will be cloudy.
The pressure is low now.
(There is always someone who is into new culture)
I brought this so that it brings an angelic vibe to our room.
I also brought a doll that is loved by all.
But I couldn't bring it due to copyright.
So I took a variety of things.
This is a music box.
That is so adorable.
I think this can cause copyright issues too.
(No, we cannot show this)
Look at how tall it is. It is just like Doyoun.
I love Kaonashi.
I have around 100 types of Kaonashi at my place.
I actually made this myself.
We only have small pictures of us for now.
(Large photo frame made by Yena)
(The details are made in the Christmas spirit)
I decorated it because it looked very plain.
(My picture)
- Why did you say ours is dull? - No.
You looked at our group photo...
- Yena. - That is a misunderstanding.
The room looks dull so we need these pictures.
(They always tease Yena together)
No. That is a misunderstanding.
It is a misunderstanding.
It's only a misunderstanding. Why are you doing this?
(She does everything herself)
(Santa Jaejae)
(Recreating Doyoun's long legs)
(Yena actually did this herself)
I prepared a lot of things today.
It's because we will be collecting a lot of evidence.
- That is an acorn. - So cute.
I thought it was someone's head.
(A head to collect evidence?)
Shall we leave this in our room?
Sounds good.
(Items for mystery club for spring/summer 2024)
(BIBI's storm glass)
(Jaejae's Foxy Jae)
(Doyoun's Kaonashi music box)
(Yena's handmade photo frames)
(Jiyoon's acorn-shaped container)
- Nice. - But can we decorate it?
(The room is more like a store than a club room)
(Will this room be transformed to become their room?)
Wouldn't Shinhee be there again?
I just remembered about her.
She told us ghost stories.
(Shinhee gave them a one-off class about ghosts in Songhwa)
The one who told us about the death of Seulbi and Danbi
that happened 19 years apart for Shinhee.
Does it mean we failed to get rid of the curse on Doyoun?
Yes.
It means I am still cursed?
(The curse was not unraveled)
(The 2118 curse that seems persistent)
Anyway, this old ghost story
is linked to the archery team too.
The first ace ended up facing that sad fate.
That became the origin of ghost stories at the archery building
which caused it to be abandoned.
Last week, right before we went back home,
we saw Hwang Mina entering that building.
She entered the abandoned building.
She was staggering.
She went in.
(Mina disappears inside the abandoned dorm)
I picked her ID up.
This is Hwang Mina's!
(The only thing they found is Mina's ID with blood)
If Mina doesn't go to school, that will be bad news.
Should we tell the teachers that we saw Mina?
Yes, we should.
To our homeroom teacher?
Can we trust them? Who should we trust?
Mr. Sanmun made a fuss when Mina entered the ambulance.
(He responded in a sensitive manner)
(Someone else was there too)
Ms. Kim Yujeong.
Shouldn't we be suspicious of her?
She was the one who entered the ambulance with Mina.
(A suspicious person who entered the ambulance with Mina)
There is so much that we don't know about our school.
Not yet.
I think the counseling club is weird too.
I think all they did was gather and eat snacks.
(Sulking)
They left after having snacks.
(Yum)
We should not believe people who are good-looking.
- Mr. Suyeol? - Yes. Be wary of him too.
The one who we only saw his eyes.
Mr. Jongdae.
- He is Mr. Jongdae? - Just Jongdae.
He is suspicious too.
What did he do that made you suspicious?
All I saw was his eyes.
It's suspicious that he is working at this school.
(We should not trust people easily)
Have you had breakfast?
I only had a tangerine.
The tangerine by the angle of Jeju, Jiyoon.
They were sent to me but it wasn't under your name.
I thought someone was trying to slander me.
(That is possible in the world of 'High School Mystery Club')
If you get tangerines, it is definitely from me.
You might even get a handover letter of a Jeju tangerine farm.
Thank you.
Let's do our best today too.
Okay.
Yes, you have to work hard, Yena.
It's because we are dull.
Why did you say that?
That is today's line!
(There is something interesting today)
(You girls are mean)
We should focus on deducting since we are boring people.
I have to eat chocolate when I get home.
(Because I am boring)
(Please be kind to me)
(It's time to get the mission card)
'Notice of the day.
Today is Monday, November 20.
Find Hwang Mina.'
Hwang Mina?
So it is true that Mina disappeared.
Places that Mina might be at.
Besides the classroom.
Investment club room.
And abandoned dormitory for the archery team.
(Or abandoned dormitory?)
Since we can't enter that building,
let's go to the investment club room first.
(They arrive at the school with determination)
We are here.
You left this behind.
Acorn!
(Struggling)
(Jeez)
(My gosh)
(Going to school is not easy for Doyoun)
Your clothes are so fancy.
(Moncler)
I think you are wearing clothes too expensive for school.
You should return them.
This school seems more deserted.
I was thinking the same thing.
Why is this school so gloomy like this weather?
It feels like it is empty.
(Nobody)
(is in school right now)
(They arrive at school full of worries)
Are we late?
We are late?
(Oh?)
Producer Yong Seungnam is calling me.
(Producer Yong Seungnam from 'Crazy News 24/7'?)
'How are you, Jiyoon?
I only found time to text you now as I have been busy.
I am reminded of all of you since it's getting colder now.
I am not trying to brag
but I won the Journalist Award of the Year last year.
It is all thanks to you.'
He won the award.
Why didn't he tell us about it earlier?
He looked so happy in the picture.
He was smiling ear to tear.
He took those pictures while smiling brightly.
Although we are happy for him, somehow we felt offended.
He should've sent us some snacks at least.
That made me upset.
Why did he text you now?
I think he is asking for information from us.
(That is just too random)
He is the one who gets awarded after all we did?
However, the only person who we can ask
for help from is him.
Let's get his help if needed.
Yes. He is the only one we can trust.
The only one who is on our side.
(The corridor is very silent)
(Thankfully, their classmates are in the classroom)
The teacher is in the classroom. I think we are late.
Oh no.
We will get scolded.
(Rushing inside)
Do you know what time it is now?
- Sorry. - Be seated quickly.
Where was I?
(Looking around)
The teachers will be having a meeting today.
Remain in the classroom and go to your clubs when the bell rings.
Yes.
The first time we were here,
Mina was seated at 2113.
She suddenly tore a paper
and crumpled it up before tossing it into her bag.
The only way we can find someone
is if that person is missing.
When we arrived at school,
I was nervous thinking that Mina was missing.
I was surprised when we got here.
Why must we look for Mina?
I was flustered for a moment.
And the five of you.
Please step out for a moment.
- Us? - Yes. Five of you.
Okay.
I have something to tell you.
(Their eyes are still fixed on Mina)
Actually,
when the incident involving the archery team happened,
do you remember that I told you to keep it a secret?
Yes.
You didn't tell anybody about it?
No, we didn't.
That's good.
It's because we are having a meeting
because of that incident.
(Exchanging gazes)
Let's go to the meeting room.
All you have to do
is to just tell them what you saw.
(Very nervous)
You don't have to be nervous. You are not being reprimanded.
We usually get reprimanded everywhere we go.
That is why we are intimidated.
That is not it.
There are a few related teachers in the meeting too.
Don't be nervous. Just relax.
It's okay.
I'm scared.
The students are here.
(Meeting room)
(The atmosphere here is heavy)
(Anti-violence in School Committee)
(They cannot stand straight)
You can stand here
and tell them what you saw.
Attention. Salute.
Hello.
(Very polite transfer students)
We are transfer students
who just arrived and are now in Class 11-1.
Okay.
I have asked students who are related to last week's
case with the archery team here.
Please explain what happened.
(Head of the Anti-Violence in School Committee, Ms. Kim Yujeong)
Okay.
Since we are transfer students,
our class president took us
on a school tour while giving us explanations.
When we went to the gym hall,
we heard someone screaming.
So we rushed into the hall with our class president
and No Jidam
was bleeding from her left arm.
There was also an arrow near her too.
The coach told us to wait for him at the counseling room
and after waiting,
we accidentally saw something which we shouldn't have.
It was the counseling notebook.
We found out that there have been conflicts
and sour relationships among members of the team.
So we decided to search the hall
and we found out that
the arrow might have been shot from the rooftop and not the gym.
It is because Jidam's wound and tear on her clothes
was slanting from top to bottom.
We went to the rooftop and what did we find there?
We found one arrow feather.
We went to the archery team room
and found out that arrows' lengths differ according to arm length.
We went to the hall for the last time
to compare the arrow's lengths with various archers' arrows
and found out that the weapon used in this case
actually belongs to Tak Sara.
So we told the coach,
the counseling teacher and our homeroom teacher about it.
Thank you for the explanation.
Can I say something as a parent of a student here?
(Nodding)
I can't believe this happened at Songhwa, our pride.
Oh my gosh.
Don't you think both sides will be blamed
if we tell Mr. Han?
All we have to do is ask the students
to make up with one another.
This case involves the top two students in our school.
We should just punish the student who shot the arrow
to solve this issue.
But...
You've heard them, haven't you?
I think this issue
does not only involve Sara.
Mr. Suyeol.
Let's not complicate things.
You're not even new here.
Things must have been tough on Sara.
I believe I am responsible for this situation too.
Therefore,
we should make it right.
Mr. Cha.
I know that you are passionate about this
but we think it is best to take that solution
for the sake of all parties involved.
You...
Don't you think so too?
You.
Student with pink hair. What do you think?
(Pink hair?)
Say something.
(The red-haired is surprised)
I think that it would be right for us
to resolve Sara's dissatisfaction.
I understand that
it is definitely wrong to hurt someone else,
but I think Sara must have endured so much
for her to decide to take that kind of action.
Someone her age was not only bullied
but also looked down on and had her things stolen.
I don't think any of us would have let those actions slide.
They don't know how serious this is as they are students.
Why did you even ask them?
Like you mentioned earlier,
let's just wrap this up amiably.
Although she is the assailant, she is a victim too.
I think they are more worried about the school's prestige
than what is bothering Sara.
I think the parent who was there
was someone who must have donated a lot to the school.
It felt like the school is tied to the funding they receive.
I have a different opinion.
I think having the tryouts
even after this case happening is problematic.
Regardless of their performance
and even if they are from the archery team,
any form of violence has to be dealt with fairly
and be nipped in the bud.
I didn't say that I am okay with violence in school.
It should never happen.
I told you that I don't think this is right.
(Trying to control their facial expressions)
What you are saying is right
but the tryouts have ended.
Since we already have the result,
we should not turn this into a big deal
and let's try to solve this among ourselves.
Yes. Thank you for your kind words.
I also heard our students' opinions as well.
Mr. Sanmun, can you please send them back to class?
Yes, Madam.
(Nodding)
I think the only person who said the right thing
was Mr. Cha Suyeol which was surprising to me.
If he has a strong opinion on this,
he would've highlighted this issue when they came to be counseled.
So I just realized that he does not have power
against those in upper management.
Punish all three students that are involved in this case.
All three of them?
Sara was wrong too.
(In the end, it made Sara make the wrong decision)
- You did great. - Thank you.
What will happen to Sara?
But the lady who said 'naver'...
Whose mother is she?
I don't think it is right for me to reveal that.
Okay.
She is very fancy.
Don't worry. Just go back to class.
Okay.
- See you during assembly. - 2113 is Mina, right?
Mina is 2113.
I saw Mina ripping a paper
and crumple it up before throwing it in her bag.
- Really? - Yes.
(What happened to Mina?)
Where is Mina?
She was at 2113's seat.
They are having an argument.
You're so noisy.
Do it properly!
How will you take responsibility?
(Guk Jihee?)
This is a classroom. Think before you act.
You're ridiculous.
You're just an orphan.
What?
What did you say?
Are you deaf? I called you 'orphan'!
Your mom
- is not your biological mother. - You!
Who do you think you are to talk about that?
I thought you were someone great
but you are acting up despite owning nothing.
You're just a brat crazy for money.
I decided to hang out with you and you're treating me this way?
Is this pin even real?
- Isn't it fake? - Crazy brat!
What's wrong with you?
Let me go!
Hey!
What is going on?
What are you doing in class?
Answer me!
This is bad. Both of you come with me.
Come with me now!
What happened to them?
What happened? Why are they arguing?
Are they close?
They are.
Jihee said that she was supposed to do her job right.
I think that girl's name is Semi.
She decided to react to that statement.
So Jihee said
that Semi's mother is not her biological mother.
I don't think friends should say that to one another.
I was listening to the others talking
and they are actually best friends.
They said, 'How could she treat her best friend like that?'.
I think both of them have done something bad.
Seems like Semi made a mistake.
Do it properly!
Is Jihee the mastermind of that?
She was scolding Semi for making the mistake.
That was a weird conversation that never happens
between friends.
Mina.
Was Mina here?
(2113 is empty)
(Jaejae and Doyoun go to Mina's seat)
(They search the seat)
(They found the paper that Mina crumpled up)
Take that.
It's now creative time. Let's get going.
Let's go to our clubs.
Those without a club, please go to the self-study room.
Let's get going.
(The students are moving busily)
(Mina was here a moment ago)
(Where did she disappear to?)
Evidence 1. Hair.
Someone's hair.
Whose hair is this?
Do you know what is even scarier?
2115 is the scariest part. Do you know why?
She was sitting at her seat.
During their argument, she did this.
She gave them more space.
(The scariest person)
She is the scariest girl.
(That is when boardgame club members enter the classroom)
(Mystery club will head to mystery club's room)
Shall we take our bags?
- This is very scary. - Yes, it is.
Why do they fight in a scary way?
(The fear does not dissipate easily)
They are so harsh.
Why are they so mean?
But they are supposedly best friends.
Things can go sour within a split second.
I heard them saying this.
She said that Semi should have done her job right.
Did things turn sour because of the part-time job?
(They put the clues together and head to their room)
I think Yoon Semi is from a well-to-do family too.
Our...
We received a request.
(A request for a case?)
(They are feeling proud)
I guess they have heard of our reputation.
(Let's see)
'Why is the mystery club's room in this state?
I have done what I have to do. So treat me well.
I have decorated this place. So don't mess it up.
Lest I quit.
Do not cause any trouble. Your teacher advisor'.
(Wow)
- He pretends to be cold. - My goodness.
People like that are very honest.
- Let's go in. - What did he do?
How did he decorate our room?
(Wow)
This is so cute!
Amazing!
(Mystery club's room)
(There are various lights)
(This place looks cozy now)
(It has beautiful vivid colors)
(Mystery club's hideout)
This is the mid-century modern style that I like!
Mid-century modern style!
This is so cute!
This is amazing. I don't mind living here.
This is the kind of lights that I like.
This is cute too!
There must be a diffuser here since it smells nice.
Girls.
This is my favorite board!
You can stick anything on this.
We went in and it was so beautiful.
When we first met Shinhee,
our room was creepy.
Now it is cozy and warm.
I didn't know that he had this kind of touch.
Let's say that I was surprised.
Our teacher advisor was like a Santa Claus.
He decorated our room to look cozy and warm
which felt like a gift for us.
I heard from the others
that he decorated our room with expensive decorations.
(Oh)
I don't know about things like that.
There are hangers too.
(Jaejae's pick / Hangers: We can hang clothes)
We can use this for that.
We can use this as our secret board.
Sounds good.
Like in 'Minority Report'.
(There is a curtain for security as well)
This is wonderful.
(After enjoying the room)
(Rummaging)
(Taking something)
(Ta-da)
(Eyes wide open)
(Wow)
There's milk caramel too.
My gosh!
Who are you?
Are you a candy?
Are you a human candy?
I am touched.
Jiyoon, you chose a barley snack.
(Oh no)
(Giggling)
This is very nutty.
(Long live local produce)
(Standing up)
Where should I put this?
Where shall I hang this?
(Oh yes. We brought our own decorations too)
Doyoun, ours are the simplest.
Let's do it right now.
We can just put it somewhere.
This spot is perfect.
(Foxy Jae found its place first)
(And next to it is Doyoun's music box)
- Done. - So cute.
(Title)
(Foxy Jae beside Kaonashi)
This is our zone.
Simple zone.
(Simple zone)
(Looking around)
(Serious)
(Giggling)
(Ta-da)
(Yena's selfie brightens up the dull room)
(Touching)
Jiyoon, check if this is okay.
That's so pretty.
So nice.
This is fascinating.
There are hangers but nobody used it.
Let's use it since we have those.
(She hangs her clothes)
There are many decorations here.
(Wow)
(This is what they found under the sofa)
(A box of decorations)
(Items for mystery solving: Flashlight)
(Taking it for now)
(Magnifying glass)
This is cute.
(Clicking)
Why are these here?
I think these are preparations for us to go to dark places.
(They get a bad feeling)
(This box is filled with items they need for today)
What is that?
(Case request box)
Shall we write down the mysterious cases
that we know for now?
Okay.
The first mystery case is
the archery team's case, right?
Yes. November 13.
(Songhwa's case: Archery terror case)
That lady in pink
might be Jidam and Seunghye's mom.
Yes.
(The mother who was against)
(punishing the bullies)
She is someone who has vested interests in this school.
She might be Jihee's mom too.
Guk Jihee? The Gucci girl?
They look similar.
Their aura.
(They have a similar vibe?)
(Another important person)
(A parent who said that violence has to be dealt with right away)
Is she Semi's mother?
But she is not Semi's biological mother?
Bi-Bi parallel universe theory.
Lim Danbi and Lee Seulbi.
What years were their cases?
September 30, 2003.
Lim Danbi.
Ace of the archery team.
(Songhwa's mystery 1: Bi-Bi parallel universe theory)
Some say that Danbi died from falling off the rooftop.
She died from falling from the rooftop.
Mystery number 2.
2118.
That's me.
(About to cry)
(Songhwa's mystery 2: Curse of 2118)
Myth of Jang Doyoun's curse.
Curse.
The candle's flame did not blow out.
I bet everybody failed too.
There was so much wax.
(Mark the assailants in blue)
There might've been bullying cases back then too.
It might have happened in the archery team every year.
They might be too caught up in that culture.
November 20.
We were told to find Mina
but she was there.
- However... - She disappeared.
Did she go to the investment club's room?
Yes. We should go there.
It's right next door.
(The investment club's room is next to their room)
Are we supposed to go there?
Shouldn't we bring this?
Yes. We will take our evidence.
(Let's take these)
Yena, take this.
There's lights here.
So it's fine even if it is dull.
What is wrong with you?
(Just joking)
Let's go.
Dullish.
No...
- Girls... - Dullish.
We should leave our box to take in cases outside.
Yes, you are right.
Isn't this the investment club's room?
(The investment club room is right next to mystery club's room)
(Knocking)
It is locked.
Really?
They should be in since it is creative period.
(Anybody in?)
(Nobody?)
(They give up easily)
Where are they at this hour?
(Where should we go to find Mina?)
Behind our classroom,
there is a list of what kind of clubs everybody is in.
Let's use that list to find the other club members
and ask for the passcode.
Okay.
(Boardgame members are still at their room)
(Entering cautiously)
(Here it is)
Kim Jaeyeong.
Ye Chaehyeon.
Jang Yeonjin.
(There are three other members besides Mina from Class 11-1)
(Where are they?)
Your phone is ringing?
It's my phone?
(Is it mine?)
It's from Mina's locker.
(They can hear a faint ring from Mina's locker)
I heard a sound coming from the locker.
It was this melody.
We usually bring our phones everywhere we go.
Does Mina have two phones?
Or did she hide it there for a moment?
We need to know the code to her locker.
(Searching Mina's place)
Why is the music so sad?
(Peeking)
It's not 2113, is it?
(No)
(She only turns the last digit)
(2118, the cursed number, is not it either)
(Searching Mina's seat)
Just now...
- Wasn't that paper the code? - The flower?
(This was what they found in Mina's bag)
(Mysterious drawing of a flower)
(Is this drawing a hint to her locker's passcode?)
There are two drawings here.
(There are two incomplete drawings in Mina's notebook)
The number of petals?
There are two here.
This is three.
(Is the number of petals the code?)
How many petals are there in the last drawing?
I think there are 8.
2, 3, 1, 2, 3, 4.
Try 238.
That is not it.
Try 0238.
(It is not 0238 either)
(We want to open it now)
(Touching)
I think there is something sticking out of this. What is it?
(Mysterious white cords)
(sticking out of Mina's locker)
I think they are connected to one another.
(Desperately wanting to open it)
This looks like the cord on a pouch.
There are pouches where we have to pull the cords to close them.
It looks like the cord on hoodies too.
We pulled it with force but it wouldn't come out.
Producer Seungnam is asking which school we are in now.
Ask him why.
Why?
He is so interested.
They have to play a boardgame.
(They head to the investment club's room again without results)
Did he hear something about the archery team here?
(Rational suspicions towards the special scoop hyena)
Then he gets all the glory.
Right?
If we were there when he got this year's Best Journalist Award,
that would've been a plus point for when we apply for university.
What?
Who is the teacher advisor for the investment club?
Who is the teacher?
Shall we go to the teachers' office and ask?
Should we ask Jongdae?
I think you just want to talk with him.
No.
(Peeking)
(We can go in, can't we?)
(Walking stealthily)
It's Ms. Kim Yujeong.
(The one who was helping Mina on the day she fainted)
(She was there during the meeting as well)
(Ms. Yujeong is suspicious in many way)
Girls.
Yes.
What time is it now?
(Intimidated right way)
Why are you here?
As the mystery club,
we are trying to solve mysteries.
So we are here to get cooperation from the teachers.
But it is now creativity period.
So can you come here later?
Where is Ms. Kim Yujeong?
The investment club is out to visit an exhibition today.
(Suddenly getting important information)
(They leave right away)
That's why it is empty.
It means we have to break into their room.
(Striding)
(Clue to Mina's location is in this room)
(The investment club room has information about Mina)
(However, the door is locked)
(Looking closely)
(She uses a magnifying glass too)
(Is the code related to the poster on the door?)
'Even ants can do it'.
Ants.
Tap, tap.
I think the clue to the code
is somewhere around us.
Let's try everything. 0917.
Isn't it 0406?
These numbers must be the key.
1973.
(Wrong)
(The point where both graphs overlap?)
What is the value in the middle?
1978? Let's just try.
(Wrong)
Let's look at it from a distance.
(Do they see something when they look at it from a distance?)
The day the values are at the extremes.
The day both graphs overlap with one another.
There are eight vertexes.
Is the code made up of eight digits?
On the day of delisting?
(Delist?)
But this is sad.
It was low and suddenly went up before it went down again.
(In the end, it was delisted)
That is like our life's graph.
That is how it is.
We won't get delisted, right?
Imagine if this is the keypad for the code.
Vertex?
I think this fits the keypad.
Right? Isn't it the size of a keypad?
The shape is like a keypad.
(There are dotted lines as the background of the graph)
(It looks the same as a keypad)
I think it is related to the lines.
Initially I started with clicking on the vertex.
(Try with the vertex of the red line)
(Wrong)
(The blue line?)
(Wrong)
(As expected, that is not it)
(Looks like it is not the vertex of the graphs)
(This does look like a keypad)
(They are facing an obstacle)
How could they go
to an exhibition on a day as important as today?
I know, right?
I'm getting busy.
Now is not the day to go to an exhibition.
(Songhwa's student union is filled with sighs)
Shall we take a picture and draw it on a paper?
In our room?
My foot hurts.
(They decide to solve this inside their room)
1... Press everything.
Yena, you wanted to do this?
(Peekaboo)
What did you do?
(How did she solve it?)
14780963.
(Yena pressed all numbers that the red line passes by)
(Correct)
(Shy)
Good job, Yena.
(All Yena fans are here)
(Ah)
She is our dear Yena.
Only innocent young people can see it.
It's something adults overlook.
There is a graph but why didn't we try pressing all the buttons?
It's something that makes you think out of the box.
I was at the back all the time
and was thinking about it.
I wondered if this was it.
I thought I'd be teased if I told them about it.
All I did was think as I felt shy.
(Wriggling)
I thought that I should do it secretly when
everybody wasn't watching.
Then it worked.
(She goes there secretly)
(While the rest are busy taking pictures)
(She solved it)
No, I was not like that.
I told you before.
I will show you how much I have changed.
I think I am doing great now.
If this continues,
I think we will be known as Yena's High School Mystery Club.
(The door is open thanks to Yena)
(Hesitant)
Don't worry. They are visiting a gallery now.
(Stock Expo)
(Many books related to stocks)
(Golden ant)
(Investment club room)
(This room is empty)
We have to find clues related to Mina.
Gathering...
'Pay membership fees at the latest by May.'
They have fees.
(Time to pay fees. Latest to pay is May)
'Club membership fees account has been changed'?
Lee Garyun?
Oh? This is weird.
Why is the name of the treasurer removed?
The total number of members is changed to 9 too.
There was an organization chart.
One person's name was removed.
The total number of members was changed too.
- Something is fishy. - I guess that person left.
Who is that person that was removed?
Is Hwang Mina in the list?
Why is her name no there?
I guess she left the club.
Was she the treasurer?
(In the list of members from Class 11-1)
(Mina is listed as a member of the investment club)
(However, her name is not there in the organizational chart)
We wondered if it was Mina and peeled the white off.
I can see the letters.
(Scratching)
It's Hwang Mina.
We wondered if it was Mina and we are right.
(Why is her name covered?)
Look at this. They did it like this.
Looks like Mina is hated in this club as well.
She was expelled from the club.
What mistake did she make?
We would usually take pictures again and hang them up.
I wonder what she did.
(Why was she expelled?)
Mina was the treasurer
but then she was expelled?
This must be related to money.
I'm certain that Mina took some money.
It is true that she has financial issues.
That is why she did part-time jobs.
On our first day in school,
Mina told Jihee that she needs a job in an urgent manner.
(Mina asked Jihee about part-time jobs)
Can I do that job again?
What job?
The one you told me about before.
What other reasons besides money are there for her to want to work?
We looked at the calendar.
The week before we came to this school
was the day they have to deposit their membership fees.
Their treasurer was Hwang Mina.
So it made me think that this might be related to money.
It is written here that they will pay the fees at the latest by May.
That must be the day they pay their membership fees.
If she stole money,
they must've found out during this time.
She asked for a job
to get back the money she took.
That is why she spoke to Jihee about it.
She must've spoken to her teacher
as it happened on the 13th.
Ms. Kim Yujeong?
Then she ended up in an ambulance after that.
Perhaps the teacher was questioning her about the money
or she was making a confession
which caused extreme pressure both mentally and physically.
I was thinking of a few scenarios in my mind.
But what reason would a high school student in grade 11
have to steal money from her own club?
Why does she need money?
(What is Hwang Mina going through?)
Where is Mina right now then?
If the nine members are about to go out with Ms. Kim Yujeong...
Mina came to school today
but she is not at the exhibition although it is creative time.
Yes.
It's because she was expelled.
Where is she then?
(Where did Mina disappear to?)
(The clue to Mina's location is in her locker)
How do we find out her code?
They must've thrown out everything related to Mina.
(They search everywhere)
(but found no new clue)
I don't see any other documents in this room.
One of the deductions we have is there was issue with their fund.
Let's decide if we should leave this room or not.
We should leave?
(They head out to find the code to Mina's locker)
Let's go.
First off, Mina was expelled.
She was actually expelled.
This candy is tasty. We should take some.
(Taking various flavors of candy)
Sorry. I'll pay you back later.
(Peeking)
You wanted that?
Yena, you are amazing.
That is why we are all in one team.
What is 5 minus 1?
- It's 4. - No, it is 0.
Right.
(All of them stopped at the same time?)
(Path to the shop)
Wouldn't we be a nuisance to the boardgame club?
No, they won't bother with us because of their boardgame.
Really?
(Let's find Mina quickly and empty the store)
Where is Mina?
What is Mina's locker's code?
We should try out the account number we saw.
They are still playing.
I bet their arms hurt.
(Obviously. This is the boardgame club)
Sorry.
What are the numbers?
1102.
I doubt she would use another account number as her code.
(It is still locked)
4570.
(She tries to fix the number in the middle)
(That is wrong too)
(It is extremely difficult to unlock this padlock)
If I were Mina...
(Even after looking at the padlock from various angles)
I don't know what to do.
Imagine that we are Mina.
One day, you get expelled from your club.
So you can't enter the club's room.
That is during creative time.
You would need to go somewhere but where?
I would just stay here.
I do think that she is somewhere.
There are empty places in school, aren't there?
Let's check those places.
Let's go to the store too.
Let's go everywhere.
She might be at an empty place.
We haven't gone to the health room, have we?
(Health room, a place where Mina might be at)
(Empty)
Rooftop of the gym.
I doubt she would be outdoors since it is cold.
(Archery team's dorm)
Should we drop by the shop first?
Let's see if she is actually in the shop.
(Only the shopkeeper is here)
Was there a student who came in here alone today?
Sometime during creative period.
No.
(Looks like Mina didn't drop by the store)
(A place Mina might be at / Abandoned dormitory)
(The entrance door is locked)
(They are busy searching at this vast school ground)
I tried thinking but can't think of anything.
We checked all places that day.
Can we open the door from here?
(The main entrance of the dorm is locked as usual)
Mina!
Mina! Can you hear us? We can hear everything.
We didn't see her at all.
So we are lost.
(Where is Mina at?)
If she was expelled from the investment club,
wouldn't she end up going to self-study?
It's because those without clubs would need to go there.
I lose my phone easily.
I would always remember what happened in my mind.
Where does someone who doesn't have a club go to?
(Let's go backwards in time)
This is what our class president said.
'Those without a club,
please go to the self-study room'.
(The class president announces that it is creative time)
Those without a club,
please go to the self-study room.
So she must be there.
Let's go to the self-study room.
Nice!
Level 3.
- This school is so big. - Right?
The self-study room is over there.
The dog at the laboratory is very scary.
(The laboratory seems creepy)
I hope we won't have to go there.
(What is it?)
It is right here.
This is a real self-study room.
(Self-study room)
(There are students who are diligently studying)
(There are also students who sleep well)
(I can get angry)
(Evidence of lots of effort)
(Is Mina here?)
(Going here)
(But she goes there)
(Walking quietly)
(Between the students who were studying silently)
(Passing by)
(Where is Mina's spot?)
Hwang Mina!
(2113, Hwang Mina)
We found Mina's spot at the self-study room.
However, it was empty.
Where else is she at if not the study room?
(Will they be able to find out Mina's movements?)
(Here)
That must be the same as the locker's code.
I agree.
(There is a padlock hanging on the locker)
(The same as the padlock in the classroom)
There are flowers here.
(On top of the desk)
(are paper-shape art paper in the shape of flowers)
I think Mina is unique.
All other students have workbooks on their desks,
but on hers are papers.
There was also a ticket.
(Ticket to an exhibition?)
(Taking)
Why is this here?
Yesung Museum?
Talk to shadow?
(A ticket that is all about shadows)
(If they look at the writing on the ticket)
Is she a shadow?
(There are pins and shadows)
(Let's see)
Don't the pins have shadows?
We flashed the torchlight against the pins.
That's when we see the shadows.
I believe that the shadows
are a code that only Mina knows about.
Is it a music sheet?
Music sheet?
If that is true, then we need to play it to understand.
I doubt the pins are placed at random.
(There seems to be a pattern to the pins)
Can you see this, Yena?
Yes.
(Getting blocked again)
(Yena is disappointed)
Look at the number of pins.
Number of pins?
(Yena is peeking through)
4, 2, 2, 2, 3, 3, 3.
If we only need the numbers, the shadows are meaningless, right?
I think we need to look at the shape.
(What if they turn on the lights from both sides?)
(Lights on the right)
(Lights on the left)
(Both sides are on)
They look like braille.
(Knocking)
(Shocked)
Can you please be quiet?
Yes.
(What if only the left light is turned off?)
(Clear)
Look at it right now.
Don't these look like braille?
It looks like braille but I don't know how to read it.
We can just search how to read braille.
We thought those were braille codes
and tried to decipher it.
Do the shapes look familiar?
(They do look somewhat similar)
No?
(Thinking)
That doesn't seem right and something feels off.
(Staring)
Those are like constellations.
(What is this?)
(Taking a picture)
(Being wary)
(They are struggling in their own way)
(They try to put the ticket on the pin)
My eyes are about to pop out.
I think Mina should join the mystery club.
It was very difficult and complex.
I searched about Yesung Museum
and all I found was about Yesung from SUPER JUNIOR.
We can't move these, can we?
(The lights on the desk makes them want to touch them)
Shall I change the lights' angle?
(The shadows change after the lights' direction changes)
(Adding torchlight too)
I will twist this around.
(They try to change the angle of the lights too)
Turn that off.
(What if they only use the torchlight?)
Try to shine it from the bottom.
(The shadow is dancing around)
A shadow show.
(An unexpected show inside the study room)
(Moving back and forth)
It looks like they are dancing.
(Oh?)
Wait.
(BIBI realized something)
(They shine it from a distance)
(The shadows look like numbers)
I think if we get the right angle,
we will be able to see numbers. How do we do it?
Only focus on the shadows on the paper.
Only the part on the paper.
There must be a reason that there is a paper there.
If we only focus on the white paper...
We need to turn on both.
Make sure the lights only shine on the paper.
I was looking at the shadows
and if we only want to see shadows on the paper,
we have to turn on both lights.
(Aim both lights above the paper)
(Moving the light)
(When they see the shadow)
(Focused)
(Oh?)
I can see something.
(Oh?)
- 71? - 73?
73...
- 73. - 25.
7325.
(Is it 7325?)
(Amazing)
(It is open)
(What clue will they find inside Mina's locker?)
It is right there.
(Eyes wide open)
Songhwa Blooming Camp?
When we opened the locker, we found an investment record.
(Stock Investment Record)
There is also an application form to Songhwa Blooming Camp.
I guess she wanted to join the camp.
I saw the poster.
(A poster on the camp is at the back of the classroom)
Shall we take this with us?
- Amazing. - Amazing.
(She cleans this place up)
Amazing.
Mina...
She is very...
(Mina is as unique person)
Does it meant her locker's code in the classroom is 7325 too?
Let's go.
There is a phone in it.
We have to take a look at the phone.
The phone rang.
Yes.
We have solved one now.
What is it?
Is creative time over?
(Students are leaving the classroom)
We need to check Mina's locker, though.
(They head to Mina's locker)
(Is the code to this locker 7325 as well?)
(It opens)
We heard a phone ringing.
- There is no phone? - No but why?
(Mina's phone is missing)
(It definitely rang earlier)
The cord is gone too.
There were cords poking out of the locker earlier.
We also heard ringing.
However, the phone is not there.
Looks like someone took it.
Was it Mina?
We looked at Mina's seat
and her bag is missing.
Looks like she left while we were away.
I thought she left.
I am certain that Mina is in a bad situation now.
I guess Mina took it.
Where is Mina?
(High School Mystery Club 3)
Where did Mina disappear to?
I don't know.
Where is Mina?
I have no idea where she went.
The clues that we haven't found should be here, right?
Girls.
(They found the secret)
(and Mina's location)
Mina is at the pawnshop?
We are Mina's classmates.
(Looks threatening)
Leave. We are closed.
(His actions are very suspicious)
(Find her before things get even more dangerous)
(However, Mina is nowhere to be seen)
Is she dead?
(They even think that she is dead)
What is happening, Mina?
(Something is ringing?)
(Songhwa is empty)
(but a scary ringtone echoes)
What should we do?
Who is it?
It wasn't just our hallucination, was it?
Can you see me?
- Isn't this like a horror movie? - Perfect on eyes, nose and lips?
This looks like a thriller.
Can we pluck these cones?
- No. - Try shaking it.
No.
- That looks hard. - Where?
Try shaking it.
I got it.
Amazing!
