Busted! (I Know Who You Are! / 범인은 바로 너!)

Did you see the photo?

This is the prettiest spot around the school.

I work at an errand service center.

People even hire me for petty errands.

But I bet no one knows

that I'm actually a detective.

Oh, this is Sangsang Art High School.

I heard I should be able to find some clues here.

They said there are some clues here at this school.

Where are they?

Where should I go to find clues?

I know that it's somewhere in this school.

- It's me, K. -Yes.

You must've heard about the murder of a female student.

She was murdered mysteriously on the reed field at Songdo Central Park.

Gather a team of detectives and find out the truth about her murder.

Right away?

Where should I go to find clues?

Jae-suk, hurry up!

The weather seems to tell us that something is going to happen.

Something already happened.

What happened?

Hi!

-It's Kwang-soo. -Kwang-soo is here.

Having you guys by my side makes me feel so protected.

-Oh, Min-young! -Min-young!

-Here comes the pretty detective. -Oh, my.

-She looks so charismatic. -Se-jeong is here too. Hey, Sehun!

Sehun looks...

Is there a fashion show happening today or what?

You look dashing today.

One person isn't here yet. The former agent.

Gosh, he's really late.

Shouldn't he be more punctual? Why is he so late?

What? Sangsang Art High School?

Detective Ahn!

Hurry up already. We have a new case.

-Detective Ahn. -It's nice to see you guys.

What's this all of a sudden?

Hurry up, please.

I told you that we have a new case.

All right.

Can you try to be a little more interested?

-Okay. -We have a case...

-Everyone is here now. What's the case? -Now that everyone is here...

First, I'll tell you guys everything

-that happened today. -Something must have happened.

-I work at an errand service center. -Right.

-I went out on a job. -And?

The job was to collect interest from someone.

JOKWANG MARKET

I'll be sure to collect the money today.

I'm not kidding.

Here you go. All done!

-Thank you. -Bye. I hope to see you again soon!

How sweet.

I should slice this gimbap now.

Hey, you know that your interest payment is due today, right?

Pay it on time, okay?

Wait, you went to collect an interest payment?

That's unusual.

Well, we do everything.

-Really? Anyway, what happened? -I got there and...

Honey, come out and help me.

Talk to that guy. Come on, hurry up.

Could you please let it slide just this once?

But you should...

You should pay it back.

Pay it back as soon as you can. I mean, please pay it back.

-What's the matter with him? - They said they didn't have any money.

Oh, the tteokbokki looks delicious.

I'd like a plate, please.

-Are you here to eat tteokbokki ? -Yes.

Then come in. You should've told us from the start.

So I sat down, but right at that moment...

At that tteokbokki place,

there's that sweet...

-What are you doing? -Are you drunk?

-Hey. -By any chance...

Look at Mr. Former Agent. He's all angry now.

He's fuming mad.

Anyway, I sat down, waited a little,

- and started eating my tteokbokki. -Here you go.

It looks delicious.

It was a mistake.

-Did you do that on purpose? -No.

What is wrong with him?

Is he an idiot or what?

Honey, by the way,

are you the one who ate everything in the Sweetness Storage?

Someone has been eating all the snacks in it.

There's this thing called Sweetness Storage.

Apparently, someone has been eating the goods in it.

-Are you suspecting that I ate them? -No, honey.

You know that I've been trying hard to stay in shape.

I know. What is happening?

Sir, what is "Sweetness Storage"?

A kindhearted student started it.

Students bring sweets and snacks to share them

with others and encourage each other.

We call it Sweetness Storage.

But someone keeps taking the goodies in the bottom compartment.

-And? -So,

I promised them that I'd catch the thief for them,

-and I did catch him, -I see.

but it was a kid.

Hello, ma'am! I'd like a plate of tteokbokki .

-Okay. Honey, one plate of tteokbokki . -Okay.

Bye.

Hold on!

That kid is the thief!

-What? -That boy?

The goodies in the bottom compartment

of Sweetness Storage have been going missing because his arms

can't reach the upper compartments.

-Yes! He's right! -Sir, I'm sorry.

-Did you take anything today? -I didn't take anything. I swear.

I kept interrogating that kid

and found out that he had this diary.

What is that?

I'm a detective.

-Are you really a detective, sir? -Of course.

This belongs to Yoon-ha.

She hasn't been coming here lately.

If you find her,

please give this back to her.

She left it here the last time she was here.

So, I asked the owner of the tteokbokki place about her.

Who is Yoon-ha? It sounds like she and this kid are close.

That kid was very fond of her,

but she actually died a few days ago.

They told me she died.

So I found out that she was found dead

on the reed field at Songdo Central Park on the 22nd.

It seems like she died under mysterious circumstances.

Are you saying she was murdered?

That's possible.

We don't know anything for certain at the moment,

but I got a call out of nowhere.

-From who? -From K.

-He called you? -Yes, he called me.

-That's why you called us. -Yes.

We should find out the truth about her mysterious death.

-Shall we see what's in her diary? -Sure.

Her name is Ji Yoon-ha. Student number 22 in Class 3 of 12th grade.

-And... Oh, here's a diary entry. -Yes, there are diary entries.

"I did badly on the math exam.

I could've gotten a perfect score."

So, she was a studious student who usually got good grades.

Yes, she must have been.

"I treated that kid I see often to tteokbokki ."

-Oh, that kid! -It must be that kid.

-That little boy. -Yes.

She was kind and generous too.

Yes, totally.

"I have a bad memory. Yeong-go, Yoon-ha... What am I saying?

I have to pick a password for my computer, and I love EXO and Gu9udan the most."

What do Yeong-go and Yoon-ha mean?

Is Yeong-go a name too?

Investigate everyone whose name is mentioned here.

Who were you talking to?

-Who were you talking to? -Okay, I'll write them down.

-What is it? -There's a photo.

Is this that girl, Yoon-ha?

But who are these four guys?

Who could they be?

The last page, here.

"S2E1N1T1." What is this?

-It looks like a code. -It does.

There's an arrow after "GTG" here.

-Get the... -Glory to God.

Get the girl.

I looked it up. It stands for "Got to go."

-It's an acronym. -I see, it's an acronym.

-We just need to decipher this. -Yes.

What is "S2E1N1T1I1F1"?

They could be a username and a password.

Are they supposed to form a word together?

"GTG" must mean

-she's got to go somewhere. -Yes, that's right.

It's an alternation between a letter of the alphabet and a number.

Don't you think it means there are two S?

It becomes "Fitness" when it's reversed.

-When you reverse it... -Yes, it is fitness.

-Sehun! -Impressive!

I just got goosebumps.

Look at the direction of the arrow. It was telling us to read it backwards.

-Oh, my. Sehun, you're amazing. -I'm impressed.

Let's go and find out.

- You guys came because you got it too. -Did you get it too?

Who do you think sent it?

Don't you think it's just a prank?

Who's pulling this prank on us?

Who do you think sent it?

I see a fitness center there.

-It's right there. -We really found a fitness center.

"SS." Our guess was right.

"GTG."

Does it mean to go somewhere?

Oh, there are...
