THREE HOURS AGO

(grunts)

SEJIN: Chanmi! Ok Chanmi!

Huh?

Sejin!

(light music)

This is...

How do you have this?

Honestly, I knew you were Wonseok's younger sister.

I didn't want to tell you that I knew before you told me about it.

Did my older brother tell you about me?

Yes.

He also shared this photograph with me.

Ah...

Seems like he trusted you a lot.

But hey...

What are you doing here so early in the morning?

Oh... The day I leave for the States has finally been set.

My flight will be ten days from today.

I guess there really isn't much time left.

We don't have much time.

That's why I thought I should tell you everything I know.

I was the one who...

left the note in your locker.

What?

Th... that was you?

I wanted to tell you the truth earlier.

But you ended up finding out about the Piano Café on your own

and making your way there.

How did you know I had transferred to Seoul?

SEJIN: It was three or four days into the semester.

-DAYEON: Hey, Chanmi, Chanmi! Hurry up. -Oh, okay, I'm coming.

SEJIN: After I dropped out of school,

I came to pick up some paperwork at school that day.

That's when I saw you.

Ok Chanmi?

SEJIN: Since then, I loitered in front of the school a lot.

I even saw you riding your scooter to school.

I thought a lot about if I should, like, approach you to introduce myself.

Then I thought to myself, what's the point of introducing myself to you now?

But then...

Then?

Ah, there's...

There's something I need to tell you first.

That video of Wonseok falling that was played in the auditorium...

it was me who played the video.

What?

(gasps)

How... where did you get ahold of that video?

I recorded it myself with my cell phone.

DECEMBER 23RD, LAST YEAR

SHARED STUDY CAFÉ

(soft chuckle)

(chuckle continues)

(grunts)

(soft chuckle)

(body thuds in distance)

(ominous music)

(groans)

(Sejin gasps)

(whispers) Wonseok...

(breathes deeply)

SEJIN: I was so scared.

I was so scared and heartbroken at the time.

(sighs) So, I just ran away.

Why didn't you...

tell the police about the video from the beginning?

Why didn't you tell them it was a murder, not a suicide?

I also thought it was a suicide.

(sighs deeply)

I couldn't bear to think that Wonseok would kill himself.

That's why I dropped out of school,

got a new cell phone, and a new number, too.

I stopped contacting anybody I knew and meeting up with them after that.

Honestly, I couldn't bring myself to watch

the video on that phone again.

(sighs lightly)

I'm not going to ever come back once I leave.

So, I wanted to resolve things before I left.

SEJIN: After hesitating and agonizing for a while,

I took out the phone I had put away and rewatched that video.

YJ TELECOM

(shaky breathing)

It was already agonizing to watch that video again, but then...

(gasps)

I saw that someone had pushed Wonseok out the window,

and I was even more shocked...

(gasps)

That's when I thought I should let you know right away.

SEJIN: I also thought I should let the other students and the teachers know.

That's why I played the video in the auditorium.

-(students scream) -STUDENT 1: It's Park Wonseok!

(ominous music)

If the police find the murderer before we do,

we won't even have a chance to get our revenge on the murderer.

That's exactly what I'm thinking.

One way or another, let's find the murderer before they do.

Sejin.

You already have a suspect in mind, don't you?

Who do you think did it?

(inhales deeply)

Ji Sooheon.

Ji, Ji Sooheon?

Did everything go okay last night?

Everything went well.

(sighs)

Okay.

Ah!

That bastard

will visit the hospital today to apologize.

(sighs) Though that punk really deserves to die.

Good work.

(light music)

Hey, Sooheon!

Huh? Hey, Jaebum.

Hey, what's up? What happened to you last night?

I'm so sorry.

I had an urgent matter. I'm really, really sorry.

Hey, you should've messaged me, or at least given me a call.

I was so frustrated I didn't think I could stand it.

But I sent you a text message letting you know

I couldn't go to the game.

Really? I didn't get a text message.

Yeah, look, no message.

Ugh, how annoying.

I turned my cell phone off without checking

to see if the message went through.

Wow, we were about to become arch enemies because of a simple misunderstanding.

I'm so sorry, seriously.

It's fine. It wasn't your fault. Things just happen sometimes.

(sighs)

SOOHEON: I'm really sorry, truly.

JAEBUM: It's really fine. Let's go see another game next time.

SOOHEON: I'm seriously so sorry. Why don't we have lunch together?

Are you at least going to have lunch with me?

(chuckles) Oh, come on.

Now it's

Ji Sooheon...

JAEBUM: Hey, Osung.

THE DAY BEFORE

-JAEBUM: Gi Osung! -(Osung sighs)

LITERATURE

What's going on with you? Is there anything wrong with this photo?

Jaebum.

Don't you know that detectives are all over the place

to work on Park Wonseok's case?

What's so bad about having taken a photo once with Park Wonseok?

Is it a problem that I used to know Park Wonseok?

Let's say you naïvely brought this picture to school

and the other students saw that you had this.

And that that caught the attention of the detectives.

Then a detective might ask you how you were so close to Park Wonseok

even though you were in different grades.

How will you answer that question?

If you say you don't remember,

do you think the detectives will leave it at that?

They'll start contacting students who graduated,

people who were in your grade, and start digging around.

(sighs)

It won't do you any good if you get involved with the police.

Jaebum.

Don't trust anyone else but me and remember what I said.

You never even knew Park Wonseok.

(ominous music)

(lighter clicks)

(siren blaring)

(camera shutter clicks)

(ominous music)

This reminds me of the incident in the dark room at Yongtan High.

(camera shutter clicks)

He was bound to the chair with tape and then beaten up.

-(sighs) -(camera shutter clicks)

REVENGE OF OTHERS

TEACHER: "The red sun is over the tip of the western mountain."

It's evening, and the sun's about to go down.

The image of the downward movement of the sun

reinforces the atmosphere of mourning.

Like this, sunsets are often used as metaphors

for descent, disappearance, destruction, or death.

Now take a look at the next sentence...

(shaky breathing)

Is there any reason why you think Sooheon is the culprit?

I saw him.

(exhales deeply)

(shaking) You saw...

Sooheon?

(suspenseful music)

(breathes shakily)

(suspenseful music continues)

TEACHER: What we know for certain is that the speaker,

who is watching the deer, is sad.

And we can say the speaker is projecting their sadness on the deer.

That's why some people say that this is the part

where the speaker's sadness starts to expand throughout the world.

In the first and second paragraphs...

(indistinct chatter)

-DAYEON: Wow, this is incredible news. -NARIN: What?

It's about Ok Chanmi. This is an incredible update.

(groans) Wow.

Ok Chanmi and Park Wonseok are actually siblings.

What?

Apparently, somebody heard this

from the detective working on Park Wonseok's case.

They're siblings.

Wow, that really hit a nerve.

So, she's been keeping that a secret? Why?

(indistinct chatter)

SEJIN: It was Ji Sooheon.

I saw him.

I saw the red shoelaces on his shoes, I swear.

-Hey. -(gasps)

I heard you're Park Wonseok's younger sister?

(laughs) Seriously, you're...

(sighs)

You've got me.

Bitch, I mean, seriously?

You're the one that went around telling everyone

that Osung and I are siblings.

I already told you it wasn't me who blabbed.

-Just stop. -Stop what?

I haven't even started yet.

Why did you keep it a secret?

Did you do that so that you could sniff around

to learn more about Park Wonseok's death?

Did you have fun playing detective

and pretending you had nothing to do with him?

It must have been a ton of fun turning this school upside down, huh?

Hey, Jihyun.

How could you even say that?

-AJUNG: A classmate died. -JIHYUN: Oh.

So you're siding with her because she's your ex-boyfriend's sister?

Why don't you two just hug and cry it out?

Shut up. That was low.

Get lost, or I might smack you, and you might end up sobbing...

-(screams) -(indistinct chatter)

(groans) Hey! Let me go!

STUDENT 1: Whoa, whoa, whoa!

-(Jihyun groans) -Fucking bitch!

Leave me alone! (screams)

-Hey! -STUDENT 2: Stop them!

-(groans) -(student grunts)

(grunts) You!

-(grunts) -(screams)

-(student groans) -(breathes heavily)

-STUDENT 3: Get up. -(groans)

(grunts)

(indistinct chatter)

(Chanmi grunts)

(both grunt)

-(breathes deeply) -(grunts)

Shit! Ha, fuck!

Hey, hey, Chanmi, Chanmi, don't do that, Chanmi.

-This fucking... -(Nakjun groans)

Hey, stop! Stop it.

-(grunts) -Just calm down.

(grunts)

HYEJEONG: Mr. Jo, what's going on at school these days?

(sighs)

Can't you see what happened to my daughter's face?

DEOKHYEON: I'm so sorry, ma'am.

It wasn't a fight. Clearly, she was beaten up.

Yes, that's what the other students are saying as well.

Expel her from school.

If you don't, you'll have bigger problems to face.

Uh... I...

I heard that Mr. Gi, Osung's father, is part of your family.

I heard about it recently.

So, since her father is the chief of the police station...

That's why I'm not just going to let this go.

Expel her from school.

(breathes deeply)

SOYEON: Are you feeling okay?

I'm eating so much.

When are you going to show me your husband's face?

(chuckles awkwardly)

Give it some time. I'll show you when the time comes.

Ugh, no matter how much I think about it, you are one crazy bitch.

I would agree. I'm kind of all over the place.

(laughs)

Uh...

What did the teacher say?

He told me to stay home for a few days and not get into any more trouble.

Meanwhile, he'll do his best to make sure I'm not suspended or expelled.

Oh, wow, he's such a nice human being.

Well, he's kind of a weasel, but he's a nice person.

Of course, since he's so ugly, he has to at least be nice.

-(Soyeon laughs) -(scoffs)

AJUNG: No wonder.

I thought it was weird how you were so curious about Wonseok.

In any case, you must have gone through a lot.

Uh, it's just...

Do you mind if we talk about him?

No, of course not.

I only hid the fact that I'm his younger sister

because I was afraid people wouldn't talk to me about him.

You see, Wonseok was a pretty nice guy up to sophomore year.

I heard that too.

That he was strong but never bullied anybody.

If anything, he protected other students from bullies.

During junior year, he made a complete 180 like he went crazy.

He started beating up other students, hanging out with bullies,

and bullying other kids himself.

In any case, if something didn't go his way,

he'd create a total mess out of the situation.

But as far as I know,

it was all because of Gi Osung.

Gi Osung?

Oh, so, are you saying Gi Osung turned Wonseok into a bully?

I mean, Gi Osung is the class president posing as a good guy.

But Wonseok was the top dog in the entire school.

Wonseok was a much better fighter,

so why would he ever take orders from Gi Osung?

I'm telling you the truth. He did whatever Gi Osung told him to do.

I've never told this to anyone before,

but what happened is, Gi Osung was manipulating Park Wonseok.

It was when I started

my secret relationship with my hubby.

AJUNG: So, we were having an intimate moment together, when...

WONSEOK: Hey, Gi Osung!

(gasps)

What is it that you needed to tell me?

Hey, Wonseok.

Did you think I was joking? Why didn't you do what I told you to?

You bastard. I told you to do whatever it took to stop Im Somi

from spreading lies that I got her pregnant.

How can I possibly stop her from blabbing to people?

Since I broke up with that bitch Im Somi,

she's been trying to drag me down by telling everyone that she's pregnant.

Whether you kill her or tear off her mouth, I don't care.

Just make sure she keeps her mouth shut.

This is your last warning.

(sighs)

Fine. Then this will be the last time.

That all depends on how you handle this.

(sighs) Yeah, that's right.

So, it's true that Osung had something on Wonseok

and manipulated him.

Ah, I did have some vague sense that that was the case.

What did he have on Wonseok?

Huh?

I don't really know what that might've been, but...

I mean, what exactly did he use against my brother

to do anything he wanted?

What kind of weakness would he have had that would've made my brother

do all those bad things?

Oh, but something that really confuses me is...

Later, towards the end of the second semester,

it was Wonseok that had the upper hand over Osung.

Like the situation had changed completely.

(sighs deeply)

The picture on the left is from the body shop murder case,

which we received this morning.

The one on the right is from the assault case,

which was reported from Yongtan High on March 17th of this year.

The commonality between these two cases is that the victims were former assailants

in school violence cases.

Also, the victims were bound to chairs with tape.

We've yet to receive the lab results,

but there's a possibility that it's the same tape.

In one case, the victim died.

In the other, the victim was seriously injured.

In the assault case, the victim's toes were crushed to pieces.

The direct cause of death in the body shop case

is currently presumed to be suffocation from strangulation.

Sir, we'll determine if there's a clear connection

between the cases as we investigate them.

Well, since this is a homicide case, the homicide division should work on it.

But I do think there's a connection between the cases.

So I want Jin Sojeong's team to join as well.

Yes, sir.

ENGINE OIL - WHEEL ALIGNMENT

JUNGGYEONG: I don't remember anything since I couldn't see his face.

I can't recall anything either

because I was getting beaten up like crazy.

YOUNG STRONG TIRE JUNGGYEONG

But in any case, I think he had a distinct smell.

Could you elaborate?

Well, it smelled like oil and alcohol.

What kind of oil? Like the oil you smell here?

Or like the oil you smell at a barbecue restaurant?

Or gasoline from a gas station, lubricant oil from a factory,

engine oil from a body shop, cooking oil from a chicken restaurant...

I think it was lubricant oil from a factory.

It smelled like oil from a machine.

Oil from a factory machine...

How about the alcohol?

Are you sure it wasn't the smell of liquor?

It smelled like the alcohol you would find in a hospital.

Alcohol found in a hospital...

(inhales deeply)

Can you describe the moment you first encountered the assailant

in the dark room again?

Well, you couldn't even call it a moment.

Shit, it's kind of embarrassing.

I was knocked out in a single punch.

Anyways.

Ugh, well, shit, he's got a hell of a punch, eh?

The culprit might be a pro.

So you mean like a professional boxer?

(laughs) Nope.

(scoffs)

Not a pro athlete. More like a pro gangster.

How about the way he talked?

Other than the fact that he used a voice modulator.

Other than that I can't really...

Did he have an accent, or talk like a gangster?

(inhales deeply)

Well, now that I think about it, I don't think he talked like a gangster.

Oil, alcohol, a lightning-fast punch, a normal accent.

(sighs)

Doesn't this feel like a mystery from a detective novel?

(tongue clicks)

You mean the assault in the dark room?

Are you talking about Sa Junggyeong?

You ran into Ji Sooheon in an alley that night.

Can you remember anything in particular from...

Wait, hold on a moment. Hold on a moment, detective.

Weren't you investigating my older brother's case?

There's a connection between the cases, so that's why I'm questioning you.

Are you saying...

that it's the same culprit?

No...

That's not what I meant.

What I meant is that I'm carrying out my investigation

and leaving it open to all possibilities.

Hey, try to remember what happened when you ran into Ji Sooheon that night.

Even the tiniest thing might be helpful.

Now, it goes without saying that our conversation here will be classified,

so this stays between us.

-Chanmi... -Is the perpetrator in my brother's case

and the perpetrator in the dark room assault case

the same person?

That's why, if you want to catch your brother's murderer,

you have to think hard about

whether there was anything strange with Ji Sooheon that night.

Sa Junggyeong?

I didn't have any issues with him at school,

nor did I have any interest in him.

Do you usually work out over there?

-Sorry? -That night,

you ran into Ok Chanmi in the alley on your way back

after working out at the Unmacheon walkway.

Yes, occasionally.

I was under the impression that you usually work out at this gym.

But you worked out at the Unmacheon walkway that night?

I didn't say that I worked out at the Unmacheon walkway that night only.

What I mean is that I work out over there occasionally.

When did you start practicing martial arts?

Since I was in 9th grade.

Oh, you must be really good by now.

With a strong punch.

Are you planning to become a professional athlete?

(chuckles awkwardly)

It's just a hobby.

I'm only asking because it's something I've been curious about.

Is it possible to knock someone out with a single bare-fisted punch?

If the person's struck at a pressure point, it might be possible.

Like on the jaw or the temples?

Yeah, well, probably.

Have you ever managed to do that yourself?

No.

(sighs)

On March 17th,

the night Sa Junggyeong was assaulted in the dark room,

there were witnesses standing in front of the student center.

A boy and a girl.

They testified that someone in a mask hopped over a wall.

If you were to have jumped over the wall,

you'd find yourself in the alley where you and Chanmi ran into each other.

Did you see anyone else in the alley?

Anyone suspicious?

Chanmi was the only person I ran into.

The shoelaces on your sneakers,

are those the ones that are normally on your shoes?

They look nice.

I switched them out recently.

Because I have some kind of a jinx.

Can I ask about the jinx?

I'd rather not talk about that unless it's related to the investigation.

Ah...

Sorry.

I'm sorry.

(light music)

(suspenseful music)

(footsteps approaching)

(suspenseful music continues)

Mother, it's me.

I'm fine.

I'm sorry. Please don't worry.

But mother...

I'm not sure where I am right now.

(birds chirping)

The kids started eating first.

(clatters)

Osung, what were you doing while Jihyun was being beaten up like this?

-(Wangdo clicks tongue) -Oh, why are you blaming Osung?

Do you really think Osung would've let this happen if he were there?

He wasn't there to stop it.

In any case, I'm not going to let this girl get away

with just an expulsion for doing this to Jihyun.

I'm going to pursue criminal charges.

Please be firm with the school when you speak to them.

Of course I will.

Oh, also, there seems to be a lot going on

at Yongtan High these days, so be careful.

In fact, the assailant from the dark room case

is a student at your school!

Isn't it better not to catch the culprit from the dark room case?

Sa Junggyeong got what he deserved, so it was just justice being served.

What are you talking about?

Justice is enforced by the police.

Because we didn't pursue that guy, he ended up even committing murder!

Did someone die?

(clears throat)

Don't tell anyone at school about this.

Of course the kids know not to do that.

But still, just be careful what you say.

I guess somebody had better be extra careful, then.

(sighs)

Hey!

Aren't you supposed to go that way?

Why should I take a detour? Everyone knows by now.

This route is much shorter.

Shit, my reputation is ruined because of that bitch Ok Chanmi.

Are you going to get her kicked out of school?

Whether it's expulsion or suspension, we can't let her leave the school.

Better that I keep her near me to make her behave like a good girl.

A good girl who will tremble in fear whenever she sees me.

I'll teach her a real lesson.

I guess you'll have a lot on your hands teaching her a lesson and all.

Now that I think about it, it's fucking outrageous.

The fact that Ok Chanmi and Park Wonseok were siblings.

She must've been spying on us, like we're the suspects.

Damn, I really can't forgive her. Seriously I'm going to kill--

(groans) Shit.

Hey, Jihyun.

Don't even think about calling up your cronies to beat her up.

If something goes wrong, that'll be on your student record.

-And then you can kiss college goodbye. -Do you think I'm an amateur?

Just don't do anything.

I'll handle this one.

In a way you'll see fit.

What a joke.

(birds chirping)

YONGTAN HIGH YONGTAN HIGH SCHOOL

(suspenseful music)

(gunshot)

AJUNG: Osung was manipulating Wonseok.

Osung was behind all the bad things he did.

You're working so hard.

Well, the school is offering me a scholarship,

so I guess I have to at least pretend to be working hard.

Don't you have class?

I have something else that's more important than class.

I'm here because your case has been opened up

by the school violence committee.

-Did you come for an apology? -No, no.

I'll apologize first.

Sorry, I know Jihyun has been an ass to you.

This is just a possibility for now, but...

things are going to get complicated for you if you're expelled

or suspended from school.

My father...

I mean, Jihyun's father, is a police chief.

If he gets mad and overreacts, things might get complicated for you.

This is why I'm saying this to you now.

I'll do my best to make sure you're not expelled from school.

And why would you do that?

I guess I consider myself indebted to him

for the things I couldn't apologize for.

Though I'm not sure if I can make up to him in this way...

Regardless, I'm being genuine, so I hope you'll take it that way.

Hope you have a good practice.

Oh, one more thing.

I'll help you find Wonseok's murderer. I'll do whatever I can.

(light music)

(birds chirping)

(water sloshing)

(light music continues)

(sighs deeply)

GI OSUNG

JUNGGYEONG: Ji Sooheon, you motherfucker. Come here.

Eh?

I said, come here, you son of a bitch.

My bros wanted to pay you a visit, you fucker.

(Junggyeong tongue clicks)

Is it possible to knock someone out with a single bare-fisted punch?

Have you ever knocked someone out?

-MAN 1: Bastard! -(Sooheon groans)

-(Sooheon groans) -(grunts)

-MAN 1: Get up. -MAN 2: You.

(Sooheon groans)

-Hey, hey! -(breathes heavily)

-Where are your balls, you son of a bitch! -(breathes deeply)

-Crush him. -(grunts)

Fuck. (grunts)

Bro, I think that's enough.

I bet the other fuckers already reported this when they passed by.

He's a pile of mush. Does he even know how to punch?

Agh, what's wrong with him? Was he just amped in the gym that day?

-(grunts) -I thought he was a good fighter.

-He doesn't seem like one, does he? -Fuck.

(sighs)

(groans)

MOK JEONGHYEON OBSTETRICS & GYNECOLOGY

He came here four days ago.

May I ask what this is concerning?

It's about a homicide case.

Excuse me?

(shaking) Did he kill someone again?

No. He was murdered.

What?

He's dead?

I know it may be traumatic to recall

the details of your daughter's case, but may I ask you a few questions?

Sure.

When Ju Hyeokgeon was here four days ago,

what did he say to you?

He told me to drop the civil lawsuit.

He stabbed my daughter to death and finished his sentence,

but he was still only 16 years old.

He's reintegrated back into society

and living a normal life as if nothing had happened.

At 18 years old.

So...

as a mom...

I needed to do something. (sobbing)

In order to make sure he'll never forget that he stabbed my daughter,

I filed a civil lawsuit against him

so that I could drag it out for as long as possible.

He came here to tell me to drop it.

He threatened me saying I'll have to pay a price if I don't drop the case...

Did anything else happen?

That was it. (sobbing)

It must be hard.

YONGTAN POLICE STATION WOMEN & JUVENILE DIVISION/LIEUTENANT JIN SO JUNG

SOJEONG: If you remember anything else, please let us know.

Why didn't you file a police report,

when you were threatened to drop the suit?

(breathes deeply)

(sobs)

-(indistinct chatter) -STUDENT 1: Leave our hero alone!

-STUDENT 2: Please don't catch him! -STUDENT 3: Leave!

-Can't you just leave? -Just go!

(water sloshing)

(suspicious music)

Excuse me?

Yes?

-SOJEONG: Your purse. -Ah...

Thank you.

(light music)

(car alarm beeps)

(suspicious music)

Come in.

You made the appointment under a fake name, right?

Yes.

I'll take care of the medical records.

I guess we won't have to see each other again.

Were the cops here?

-Did something happen? -Didn't you know?

What do you mean?

I guess you're here because you didn't know.

Ju Hyeokgeon is dead.

Excuse me?

(gasps)

-Hello. -Oh, you're here? Take care, boy.

(door opens)

Hey.

You never saw that, okay?

Just forget you ever saw this. Do you understand?

Yes, I do.

(strained groan) Good.

What is it?

Anything else you can't talk to me about at home?

You know the girl who beat up Jihyun?

Please punish her without getting her expelled from school.

Huh, what are you talking about?

She's going to be expelled and charged as a criminal!

Why are you saying things that will upset Jihyun?

Dad.

She's kind of poor.

And to be honest, Jihyun's not completely innocent either.

If I can persuade Jihyun to make up with her,

it'll be beneficial for Jihyun's reputation as well.

So do you really think you can persuade Jihyun?

Yes.

All you have to do is just pretend you don't know anything about this

and not do anything.

Hmm...

So you want to resolve this on good terms.

NOTE: ASSAILANT IN A MURDER CASE INVOLVING A MIDDLE SCHOOL STUDENT IN 2019.

DOCTOR: Thank you.

-SOJEONG (on phone): Hello? -Hey, honey.

Can you get off work on time today?

Yes, I'll leave on time today. How about you?

INSEON (on phone): Then I should get off work when you do.

What time can you be at that bowling alley?

Um, in about 40 minutes?

INSEON (on phone): Okay, I'll see you in 40 minutes.

Okay, see you then. Bye.

That looks like the culprit,

but it's peculiar that he's wearing a backpack.

He used a lot of tools to carry out the crime.

A mask, tape, gloves, urethane foam used to block the camera.

It smelled like oil and alcohol.

How did I miss this?

Excuse me?

The smell of oil, the smell of alcohol...

It's the bowling alley.

It's the oil on the bowling pins

and the alcohol that's used to wipe it off.

OWNER: Sooheon! Sooheon!

Your friend's here.

Dead?

-What? Why would Ju Hyeokgeon be dead? -(breathes shakily)

-Are you sure you're not mistaken? -The cops were at the doctor's office.

Shit.

(breathes shakily) Hey, it wasn't me.

I didn't do it.

Hey, Sooheon.

You'd better pull yourself together.

I... I'm fine with whatever you did. (breathes shakily)

We just need to decide how we're going to deal with this.

Agh, I just hit him a few times. I didn't do anything else.

Think about it carefully.

Are you saying I got carried away and killed him?

(sighs)

(inhales deeply)

How did he die?

I don't know.

(breathes deeply)

When I left the body shop,

Ju Hyeokgeon was shouting, asking for forgiveness!

He was alive!

Then should we turn ourselves in?

Do you want to just go ahead and confess to the police that you only hit him?

No, that won't work.

It's better than being labeled as a murderer.

(exhales)

I can't go to jail right now.

(sighs) Agh, I can't right now.

(Soyeon inhales deeply)

(both sigh)

(sighs)

(shouts) Shit!

(Sooheon groans)

(ominous music)

(laughs) Yes.

We're from Yongtan Police Station.

Well, how can I help you?

Ji Sooheon works here part-time, right?

Where does he store his personal items?

His personal belongings are in his locker since he has to lock them up.

I'll be taking a look through his things.

Excuse me, what's going on?

Did-did Sooheon get into some trouble?

Why are you searching his belongings?

(ominous music)

What's going on?

Don't you need a search warrant?

Ji Sooheon.

-(exhales nervously) -If you don't open this for us,

you'll be escorted to the police station, and we'll break this locker open.

We can secure a search warrant under exigent circumstances.

It's your call.

What?

It's just a uniform and a backpack.

For a student?

May I close this?

Excuse me, what exactly are you searching for? Huh?

If you have reason to believe he's a suspect,

you should at least be able to explain what's going on to us!

-What did Sooheon do wrong? -Detective Hyun.

Go get the master key and check every locker here.

Including the machine room.

I'll check inside the bowling alley.

JONGGUK: Yes, ma'am.

Wait...

Did you say you're going to check every single locker?

May I search the machine room first?

Wait, wait, wait, hold on a second. Hold on a second.

Isn't this too much even for a police officer?

Rushing in with a bolt cutter to cut open a lock? Do you have a warrant?

When there's a risk that the evidence may be destroyed,

we can secure a warrant afterwards.

-(sighs) -Step aside.

(sighs) That's enough. Just get out of here.

Get out of my gym right now.

So what if you're a cop? Get out!

(groans)

You'll get hurt if you lay hands on a cop.

-It's a homicide case! -(groans)

Don't mess with me.

This is so ridiculous. What the hell? I think you're seriously mistaken.

What exactly is she looking for?

Sooheon, she said she's investigating a murder case.

(scoffs) Wow, she's making me lose it.

Wow, seriously. Shit!

Can I see your room?

You need to first tell me what's going on.

What is it you want from me?

What is this about a murder case?

If you're not good at your job,

why don't you make a career change?

And stop bothering me.

(sobbing continues)

I was here...

last night.

Jaebum.

Did you suddenly remember

the horse riding course you used to come to?

(chuckles) No.

It's not that I remembered this place.

I woke up and found myself alone in the stables in the middle of the night.

When I called my mom and told her there was a horse next to me,

she came here and brought me back home.

I guess I took a taxi and came here at night.

Standing alone in a stable in the dark at night.

As if I'd been abandoned.

It was scary.

Of course, man.

If you remember something and want to take a visit,

just give me a call first.

Sure, thanks.

But last night,

I was able to retrieve a memory in the midst of my fear.

I wasn't injured in a traffic accident.

It wasn't a traffic accident that kept me in the hospital for six months.

Jaebum.

I...

I tried to kill myself here at the stables.

(scoffs)

Everyone lied to me.

Isn't that right?

Jaebum! (inhales sharply)

-I... -I know that you...

were just trying your best to do whatever my mother told you to do.

I'm grateful for that.

But Osung...

can you promise me you'll be honest with me?

Of course, Jaebum.

I'm always on your side. I'm always genuine with you.

Osung.

Was I the one

who killed Park Wonseok?

(ominous music)

(breathes heavily)

(exhales deeply)

(breathes heavily)

Chanmi.

Can we talk for a moment?

About what?

Don't you have something to tell me?

What do you mean?

You're the one that wanted to talk.

The cops came today to search my locker.

Aren't you curious why they came for me?

Sa Junggyeong's case, the dark room case.

You're being investigated as a suspect.

The police came to question me as well.

They kept asking me about the night I ran into you in the alley.

Isn't that the reason why the cops came for you?

-That's right. -When the cops searched the place,

did anything happen?

-No -Then it's all good.

-What was it you wanted to tell me? -Ah...

It's nothing.

I just wanted to ask is all.

-It's late. Get some rest. -Okay.

Get some rest.
