Original subtitles

That's enough booze for me, so I better bet going.

Hold on.

What? What did you just say?

He's a psychopathic...

killer.

Are you okay?

I got to see what kind of people...

you hang out with.

It was fun in a way.

(Emergency Exit)

I realized...

that killing the weak and powerless...

no longer fulfills the desires that urge me to act.

But I'm a psychopathic killer.

What if I want to kill someone again?

I'll think about it then.

(Psychopath Diary)

(Episode 5)

Was that necessary, Bo Kyung?

You're off-duty tomorrow, right?

Can you change shifts with me?

I can,

but what is this about?

- Are you moonlighting again? - Well...

I have my reasons.

I can't believe you.

I may seem a bit ditsy to you,

but I'm a police officer too and your partner.

I know that you've been...

looking through case files and investigating them.

Taek Soo...

Whatever.

I'm done covering for you.

If you're working a case, let me in on it.

If you're moonlighting, give me my cut.

I'm done doing you favors.

Okay, follow me outside.

So that predator you've been after,

the serial killer,

turned out to be Yook Dong Sik.

Don't you think this is too far-fetched?

The Yook Dong Sik we know?

It's why no one suspects him.

He seems like the nicest guy on earth.

Still...

We caused his amnesia, remember?

What if it was all a lie?

After attacking...

the homeless man in the public restroom,

he planned to kill him at the construction site.

Then he saw us approaching, so he ran into us on purpose...

just so that we won't suspect him.

Doesn't it seem like gibberish to you?

But then he pretended to have amnesia.

There was no point in us asking why he was there.

I tailed him for a while,

and so many things seem suspicious to me.

You tailed him?

Have you been stalking Mr. Yook?

Moonlighting would've been better.

But I have a witness statement.

What have you always told me?

You said that I should play detective when it's plausible.

That's why...

Anyway, leave it to me to find the evidence.

All I want from you is...

All right, I'll change shifts with you.

However, just make sure...

that this is worthy of the police's time...

and the taxpayer's money.

As my partner,

you will have to persuade me.

If you don't, I'll go to the captain.

I will.

Track Yook Dong Sik's every movement in the office...

and report back to me every day.

Yes, sir. In terms of his work though,

Mr. Gong is reporting back to you.

Didn't I say his "every moment"?

How many times does he go to the bathroom,

what does he talk about in the lounge,

who he hangs out with, and how he's viewed.

Get me the information by any means necessary.

Observe him by any means necessary...

- and report back to me. - I'm right, you know.

- So? - Let me.

There. See?

That's when I figured it out.

- No way. - Gosh, I'm jealous.

Were you at the Winner's Club party with Director Seo?

My gosh.

This is the first time I'm hearing he took someone there.

This proves that you're his man.

I'm Dong Sik's man...

which makes me Mr. Seo's man too.

- Gosh. - Unbelievable.

That's hilarious.

Did you go to the party wearing something like this?

- Yes. - You should buy something nicer.

- It looks good to me. - It's fine.

Still, he should wear...

something nicer to a party like that.

Dong Sik said that all he needs is his gaze.

Still, it can't hurt.

What if I got a bow tie?

Dong Sik.

I'm Park Chan Oh of Team One.

I'm Oh Sang Sik of Team Two.

We said hello at a team dinner once.

Yes, right.

Which stocks have you been eyeing lately?

You're chummy with Mr. Seo. Do you have any tips?

Inverse futures seem decent to me these days.

What do you think?

Sorry, but that isn't my department of expertise.

Wait, hold on.

I know you have the inside scoop.

Darn it.

Inverse futures?

I feel like I can almost wrap my head around this.

(Asset Management Team Three)

What are you doing when the market is closed?

We should work more efficiently and logically.

That's what Director Seo said.

Until when are we going to work...

while tiptoeing around other people?

Come and see me if you have anything to report...

or go home early instead of wasting time here.

Yes, good day, sir.

I'm staying until 7pm.

Come on. I said you should go home.

I might even work late.

Good job, everyone.

Good job, sir.

Yes, you too.

- Bye. - See you tomorrow.

I'll see you tomorrow too.

Going home at this hour is the right thing to do.

Yes, of course. Nice one, Dong Sik.

Did you get home safely last night?

Hello, sir.

Hello.

Gosh, there's no need for that.

Bye.

We're able to go home early...

thanks to you.

Did you have anything to say?

No, you should go.

Yes, sir.

Take care.

So you're going to act as if nothing had happened?

It's me. I need eyes on someone.

Right now.

- Bye. - See you tomorrow.

I hear your barbecue restaurant is doing well.

Lucky you.

Is this all though?

Is this all?

Sorry, but I can't get you any more.

Then our patience has run out too.

Hold it properly.

Promises between friends are supposed to be kept.

Are you kidding me?

Does our friendship mean nothing to you?

You brats over there.

Do you have a lighter?

We only smoke electronic cigarettes.

Young thugs these days...

don't carry around lighters.

That's smart.

And who on earth are you?

Me?

Your future.

You're already reeking of alcohol at this hour?

Alcohol?

I doubt it. I probably smell like a prison cell.

You see,

I was just released from one.

Funny, right?

- Right? - Gosh.

You brats.

Will it take me slicing one of your heads off...

for you to get your act together?

I get scared easily, you know.

You almost made me piss my pants.

Anyway, take this...

and buy a lighter, old man.

Did you tell them about the game today?

I told them to meet us at the Internet cafe.

Right, I'll meet you there then.

Kids these days don't respect their elders.

Instead of reasoning first, their fists come shooting out.

Had it not been for my frozen shoulders...

I'm still grateful though.

Most people just keep walking.

Why are you letting them beat you like that?

Are you the neighborhood drum?

Look who's talking.

Did you seriously cut me off when I'm talking?

Why don't you take the time to work out instead?

Make yourself look like you can beat them up too.

That's what you should aim for.

If not, at least make yourself look formidable.

Like this.

You! What do you think you're looking at?

What?

What are you looking at?

You can't just act tough in front of everyone.

What happened to your face? Did he hit you?

No, sir.

Do you know him?

- Dong Chan. - Get lost.

Mind your own business.

Dong Chan!

Please let me explain.

It was them. Those two guys over there.

My gosh, I told you to attack!

Just quit playing if you're going to be like this.

Hey, you guys.

By any chance, did you guys hit Dong Chan?

What if we did?

- What are you going to do? - I'm sorry for interrupting,

but can we please talk?

You guys don't know who he is, do you?

You guys are dead meat.

- What's going on? - What's all this?

- Who are you guys? - What's going on?

Hey, something happened. I want you over here.

My goodness, what is this leaves a scar?

It's okay.

How clumsy are you? You seem to fall down all the time.

Do you think it's because he's weak?

Should we get him some oriental medicine?

What are you talking about?

The reason he's so weak is because you always treat him like a baby.

Some guy provoked the school bullies and ended up getting dragged away.

- Dong Chan. - Look at him.

He spends all day staring at his cell phone.

No wonder he always falls down.

- What was he thinking? - I feel so bad for him.

- I like what you're wearing. - Maybe he had a job interview.

- You look nice. - Look at him.

- My gosh. - Seriously.

Do you really think it's okay to just watch them from afar?

Just watch.

We'll soon be able to see Dong Sik's true identity.

He looks so pathetic.

Hey, do you work?

- You must have some money. - "Money"?

- We also take credit cards. - Is he serious?

I heard you can take out a credit card loan these days.

You know so much.

("No Country for Old Men")

What's the biggest thing you lost from a coin toss?

What's he saying?

Heads or tails? You choose.

Are you crazy?

This coin was made in 2002.

That's exactly when you guys were born.

It's just the right coin to settle your fate.

Hurry up and choose.

Heads or tails?

Shouldn't we bet on something first?

How about 1,000 dollars?

That's already been done.

I already placed a bet.

On what?

Your lives.

Look at him acting like all brave.

Hey, take a look at his face.

That line is from a movie.

Haven't we seen enough?

You asked me to convince you. Just stay here and wait.

He'll soon reveal his true identity.

You little jerk.

In the past, I would've buried them alive.

But I need to control myself.

Because I'm no longer who I used to be.

You punk!

I've actually been thinking about getting a massage...

because my body's been so stiff lately.

That feels really nice.

What? Don't tell me you're done already.

What is this psycho saying?

Come at me.

I can take this all day.

Dong Sik!

- Are you okay? - What are you doing here?

That's what I want to ask you!

Why would you get involved just to get beaten up like this?

What are you talking about? I wasn't getting beaten up.

I just wanted to talk to your friends.

Dong Sik!

I won't talk back from now on. I'll give you whatever you ask.

So please stop.

Hey, you talk as if I'm a beggar.

Your brother asked for a massage. Get out of the way.

I'm sorry. I apologize for everything.

Please don't do this.

Why are you sorry?

They're the ones...

who should be sorry.

I'm just trying to teach them that, so don't interfere.

No, stop. They can be really scary.

- You don't know what they'll do. - Stay out of it.

Dong Chan, your brother asked us for a massage.

- You guys, wait. - Let him have what he wants.

- No, wait! - Stay out of it.

Dong Sik!

You look exhausted.

You still have some energy, right?

Hit me.

Do you really want to die?

- Dong Sik! Dong Sik! - Stay out of this.

Stop!

Dong Sik!

I think we should ask for backup.

Bo Kyung!

I'm sorry, guys!

Will you please stop? Dong Sik!

My instincts of a psychopath are starting to make...

my blood boil.

They probably have no idea...

that I'm trying hard to suppress that.

Why is he laughing? It's making me feel uneasy.

Do you think he hurt his head?

What if something bad happens?

I don't care. Keep beating him up.

What are you doing? Finish him.

I think we've done enough.

- Forget it. - Hey, stop.

- Ask for backup right now. - What?

Okay.

- Who is she? - What does she want?

Hey, you little punks!

- Don't move. - My gosh.

- Don't move. - Officer.

- Are you here alone? - There are other officers.

No, I'm not here alone.

- Don't come near me. - What do you want?

You brave little jerks!

- You guys are dead! - Over here!

- We're here for you guys! - Over here! I'm a constable!

We need your help!

- Come over here. - Let me go!

Sir!

Sir.

Why did you let them beat you up?

I don't mess with weak people.

My gosh, I can't believe you're still bluffing.

- That hurts! - Did you call me a weakling?

Let's take you to the hospital.

We want to talk to the captain.

Captain! Where's the captain?

- We want him here right now! - Where is he?

- Will you please calm down? - What did you say?

- Please calm down. - They're just kids.

How could you treat them like they're criminals?

They are criminals, sir.

They beat someone up in a group.

- It's considered special violence. - The other person was an adult.

Are you sure he didn't hit them back?

My kid got injured as well!

Just shut up, will you?

- What? - What?

What did you just say?

"Was he cut up?"

She was only asking if he was hurt too.

Right, Bo Kyung?

Are you kidding me?

Do you know who my husband is?

Does that change anything?

The victim didn't throw any punches or even grab anyone by force.

At least seven boys assaulted him as a gang...

and that was witnessed by two police officers including me.

If...

kids aren't taught...

the consequences of their actions...

or what is it that they did wrong,

they become monsters in adulthood.

You as parents don't seem to want to do the job,

so I will give them a detailed lesson instead.

You're all done.

Just stay in bed.

I'm fine.

There aren't any broken bones.

Seriously?

Serves you right for trying to be cool.

I thought you were going to die.

Why did you take it that far?

I'm not worth it.

I don't call you my brother,

I belittle you, and say nasty things in your face.

I have amnesia, you know.

I don't remember any of that.

Enough with the tough guy act.

Also, stop mimicking what you see in movies.

You look like a loser.

Why you little jerk...

You brat.

Unbelievable.

Dong Sik? Dong Sik!

My gosh, what happened to you?

- Gosh, it hurts! - What? I'm sorry.

- Oh, no. - I'm sorry.

Still, the issue was solved thanks to Dong Sik.

Dong Sik, thank you so much.

It was nothing.

Well, you look fine to me.

Goodness.

Here's my report.

I watched him all day,

but tailing him again will only be a waste of time.

Could he have known that you were watching him?

He sniffed me out?

Him?

I was a detective for 20 years...

Okay, fine.

Could there be some kind of misunderstanding?

I said, I got it.

Hey, over here.

You really are a police officer.

Look at that uniform.

I'm not wearing it for your pleasure,

so cut the commentaries.

What will you have? The same one?

I'm sorry to have you tell you this,

but we get reported by people for neglect of duty...

even if we have ramyeon on duty.

Just cut right to the chase.

That psychopath from the other night.

If I had known he was saying lines from a movie,

I would've punched his face in.

Because of that incident, I developed a sleeping disorder.

So all I could do is stare at the TV.

Darn it.

Then came on a movie...

with lines that were identical to the ones he said.

You can say I was lost for words.

What happened to Seo Ji Hoon is a lie too.

He picked up on the hallucination of the druggie...

and made it seem like he did it.

Is that why you asked me here to tell me?

Not exactly.

I consulted with a lawyer...

to figure out a way to ruin the jerk,

but reporting him for threatening me...

didn't seem gratifying at all.

See if he has any skeletons in his closet.

Someone as educated as you...

should know the difference between cops and PIs.

I put in a generous amount.

At least count the money and then decline my offer.

Call me again...

and I'll drive this into your brain.

Report me for threatening you too.

I'll return the favor by turning you in for bribery.

See you.

Gosh.

Officer Shim, what brings you by?

I figured you'd have trouble swallowing solid food.

I'm always putting you out, aren't I?

- I'm sorry. - Gosh, don't say that.

It's not true.

To be honest,

I'm the one who had misconceptions...

Excuse me for a second.

Who is it?

What...

Boss.

What?

I'll serve you as my boss...

from now on.

Stop it!

You seem drunk, so...

Yes, I had a drink.

You can ignore me all you want.

It's all good.

I'm not that young, but I've done nothing to be proud of.

So I understand how I can seem useless.

But I, Jang Chil Sung,

have survived this world...

with nothing but my genuine...

- loyalty. - Stop it already!

It's what got me this far.

Your chic ways and personality...

have made room for you in my heart.

So please remember...

that my loyalty for you is real.

Yes, I will remember that, so...

Unless you agree...

to let me serve you,

I will not move an inch...

from this spot.

I'll die. Just kill me right here.

That's your specialty, isn't it?

Just kill me!

Stop it already!

Just kill me.

Is something wrong?

It's nothing. My neighbor's here...

but he's fully intoxicated.

I won't be long.

Boss!

Gosh. Okay, fine.

Boss, you're so warm.

No wonder...

he was able to recite those movie lines.

"Memoir of a Murderer."

("Angels and Demons")

[VIU Ver] tvN E05 'Psychopath Diary' "He's Not Who He Seems" -♥ Ruo Xi ♥-

("Memories of Murder")

"Memories of Murder."

Do you remember the final shot of that movie?

I'm not sure.

The old retired cop, Park Doo Man,

goes to the spot where the incident occurred a long time ago...

and glares right into the camera.

As if he was looking for the perp...

among the viewers in the audience.

Apparently, the director said...

the Hwaseong serial killer...

will definitely go watch the movie.

So, the person the main character looked at in the end...

was the real killer's face.

Do you think he really watched it?

I bet he watched it several times, not just once,

reflecting back on those moments...

and feeling pleased that he didn't get caught.

You totally seemed like a profiler just now.

Come on.

I'm just a fan of thrillers.

Then you must be interested in criminals' psyche...

and things like that.

Well, sure. I am.

Why?

Is there a case you're investigating or something...

that I can help with?

What?

Is it a murderer?

- Well... - A serial killer?

No, forget it.

Tell me. Who knows? I may be able to help.

Next time.

I promise to let you know if I need help.

What? Okay.

I took too much of your time.

I'll let you rest.

- Good night. - Yes, thank you.

I think I've found the answer.

A way to resolve my dangerous urges in this world...

filled with weak losers.

If I must kill someone, I can just find someone...

stronger and more evil than I am, and kill him.

The serial killer that Officer Shim is chasing.

I wonder what he's like?

I'm excited.

How's Ji Hoon doing?

He isn't himself.

He stays locked up in his room.

Maybe we should send him abroad for a short while.

Then the chief director position...

In Woo will have to fill the spot...

until Ji Hoon comes back.

Do you plan to bring him back?

If he were going to crumble that easily,

I wouldn't have even thought of having him succeed me.

- Don't you agree? - Of course.

He's tough.

Ji Hoon?

Do you really think that?

If not, he'll keep getting stronger.

If there's someone who acts like a close brother...

but can stab him in the back at any moment...

is always by his side.

Do you still suspect me?

I always suspect people...

since that's how I survived.

- Take it. - It's okay.

There's no call that a businessman doesn't need to take. Ever.

What's gotten into you, inviting me over like this?

What did you need to tell me...

about Yook Dong Sik?

I don't like...

that jerk.

Fire him.

- Why? - Why else?

You saw...

that a nobody came at me.

I can't fire someone just for that.

Even for me?

What if I refuse? What will you do?

I'd probably go to your brother-in-law.

What will happen if I tell him everything you did until now...

was to take down Ji Hoon?

Would your chairman sit still?

I can expose you for embezzling company funds and hiding it...

in real estate abroad.

You'll go that far to protect Yook Dong Sik.

My, my. I'm so curious, I can't stand it.

Does he have something on you or something?

Do you want to know?

I'll tell you...

what I'm hiding.

Right?

You rat.

You're nothing.

How dare you threaten me?

Do you take me for a joke?

Don't mess with me!

(Energy drink)

(Delete)

(We Will Deliver Only the Truth)

What...

(Shinsung Securities' Joo Yeong Min's...)

(Suspected Embezzlement)

What...

An executive at Shinsung Securities,

a leading stock firm in the country,

allegedly embezzled tens of millions of dollars from the firm.

The police urgently searched his office and home...

only to find out that the suspect had already run away.

Thus, there seem to be difficulties with the investigation.

- Yes. - Dad, we're here to eat...

Uncle.

Bo Kyung, look who's here. It's Jae Joon.

Jae Joon's here.

Sir, it's an honor to meet you. I'm your biggest fan.

- Thank you for your work. - Thank you, sir.

Uncle, what brings you here?

I had an appointment nearby, so I figured I'd drop by.

It's been a while since I've seen your dad.

We're very glad that he came.

You're going to eat with us, right?

No, I need to get going.

Where are you going? You should stay a bit longer.

You should visit more often. As you can see, he really likes you.

Okay, I'll come by again.

- I'll see you. - Okay.

Bo Kyung, can we talk for a moment?

How are things going with the investigation?

I thought I was onto something, but I was completely wrong.

I'm not sure if this will help.

But how about you focus on the dates of his murder?

I also thought about that.

But I only have three cases to compare from.

I know that's not enough to estimate a specific cycle.

But according to your information,

he's moving in a certain pattern.

He has his own set of rules,

and he specifically picks out his own target and method.

I'm sure he has his own principles...

on deciding when to commit a murder.

March...

fourth.

(Suicide incidents)

(Search)

Bo Kyung, aren't you going to go home?

March 4.

April 22 to 28.

September 18.

Does anything pop into your head?

What?

- What? - Oh, right.

When did we find the broken toilet tank lid?

I think that was September...

September...

It was on the 13th.

Yes, that's right. Kim Myeong Guk died on the 18th.

But his first attempt to murder him was on the 13th.

If the culprit has some kind of a pattern,

we should focus on the 13th rather than the 18th.

Yes, that's right.

(September 18)

(September 13)

March 4.

April 22 to 28.

September 13.

(Yook Dong Sik)

Mr. Yook?

Are you busy?

No, not really.

Why do you sound so down?

I'm just a little stuck with an investigation.

My gosh, really?

But don't you think it'd be better to let go of it for a while...

instead of just holding onto it?

I also felt a little frustrated today.

So I'm planning to go to that place. Would you like to join?

"That place?"

The numbers we got as a clue...

have some kind of a pattern.

That means the passcode is...

Nice!

Did you see that? I got it right on my first try.

Here's the key.

What? You got the key?

You're good.

You're really out of it today.

I'm sorry.

I thought this might cheer me up.

But I can't get rid of the thoughts in my head.

Is something troubling you?

Are you having trouble...

with the investigation you talked about last time?

But why are you so interested...

in my case?

I couldn't really sleep at night.

So I kept watching the movies I have at home,

hoping I might be able to retrieve my memory.

And that's when I got reminded...

of what you said to me back when I was struggling...

because my colleagues at work were treating me like an outsider.

"Do what your subconscious mind tells you to do."

You think that's going to help me...

catch the kind of murderers you see in movies?

March 4.

April 22 to 28.

September 13.

Does that remind you of anything?

That's not enough information.

I guess you're right.

You found three murder cases.

And as for one of them,

the estimated time of the victim's death...

is within the course of a week.

So that means the victim was found at least 3 to 4 months later.

Yes.

Keep talking.

Let's see.

March 4.

April 22 to 28.

September 13.

I wonder what happened?

Remember when I told you about "Memories of Murder?"

- Did you watch that movie? - Yes.

In that movie, it suddenly starts to rain.

And someone sends...

a song request to a radio channel asking them to play...

Yu Jae Ha's "Gloomy Letter." That's the day the murder occurs.

So I'm sure these dates...

Wait a minute. These dates...

somehow sound familiar.

What is it? Is there anything that comes to your mind?

These dates...

This is called KOSPI 300 Inverse Futures.

So in other words...

this is the stuff that makes a profit...

when the KOSPI goes down.

Okay, let me explain.

The lines you see on this chart...

are called trend lines.

The green lines are the five-day moving average.

The red lines are the 20-day moving average.

But why are you showing me this?

Take a look at when the green lines break through the red lines.

Look.

March 4.

April 24.

September 13.

I knew it. There was a pattern behind the murder dates.

That's not all. If this is the actual pattern,

that means there's one more.

(July 8, 2019)

There might be a case you haven't found out about.

"July 8?"

Thank you.

Can you please open the door?

Thank you, Mr. Yook. Thank you.

Officer Shim, wait for me.

Aren't you guys going home?

My goodness.

Then let's have a meeting. You can show me your proposals.

Go ahead and get ready.

(Asset Management Team Three)

- Sit back down. - Okay.

I liked the place we went to last time.

It seemed like your partner had fun.

Mr. Yook, when do you plan to get off work?

There's something I need to check. Would you like to come with me?

A serial killer who committed a minimum of four murders.

I don't know who he is.

But he's just the right prey to satisfy my desire to kill.

We should get together and have some fun.

- Goodbye, everyone. - Goodbye, sir.

Get ready for the meeting.

You probably expected it,

but to be honest, I'm chasing a serial killer.

- Who is he? - Well...

I'll tell you the details later.

Okay. That's right.

You can't disclose information regarding an ongoing investigation.

That too,

but it's because I'm not confident yet.

- Sorry. - No, no. Not at all.

But thanks to you finding a pattern to the specific dates,

I found a very strong case.

It's a missing persons' case...

You think the person was murdered.

Yes.

If I'm right, this case may be...

a very important turning point.

If I fail to see something and miss it,

please let me know.

Of course. Leave it to me.

- Hello. May I ask you something? - Sorry.

Okay.

- Hello. May I ask you something? - Sorry.

Hello. May I ask you something?

I'm from Naksan Police Station.

(Shim Bo Kyung)

I don't speak Korean well.

Who are you people?

Why are you loitering by my factory?

- Is this your factory? - That's right.

Are you guys reporters?

No, I'm...

My gosh. Sir.

Hello.

Well...

I'm...

an analyst at Daehan Securities.

The name's Yook Dong Sik.

(Yook Dong Sik)

Didn't you get the call?

Gosh. I said I'd be here to check out the site.

I guess you didn't get the message.

Darn it. Ms. Kim, why that...

What's her problem?

But this lady is...

Hey, Bo Kyung.

Did you forget your business card again?

Seriously.

She's still an intern.

We don't have a separate IR point person, so talk to me.

As you know, we possess 12 different patented technologies.

We plan to double production starting the second half.

Double.

That's awesome.

But where did that lady go?

Well... I got a call from HQ,

so I sent her to do something.

These are our company's financial reports for this year.

Would you like to see them?

Sure.

There's a delivery truck coming tonight, so check it well.

Okay?

Yes, sir. I'll move this into the warehouse.

Okay. Thanks.

You speak Korean pretty well.

Are you an illegal alien?

Don't worry. That's not why I'm here.

I'm not an illegal alien.

Then why are you so afraid of me?

I'm not afraid of you.

You're in my way.

Are you afraid of the owner?

Are you being treated unfairly or something like that?

No. The owner is nice.

I'll get out of your way if you answer a few questions.

How long have you been working here?

It's been one year.

Then you must know Hong Jin Goo,

right?

What was that?

Did you hear something?

I'm not sure.

What?

I didn't hear anything.

- Sir... - I'm back!

Where were you until now?

Why didn't you tell me Daehan Securities was coming?

What? What do you mean?

People don't do their jobs anymore.

There must have been a mistake.

Who are you people?

You know him, right?

No.

Then why can't you look me in the eye?

If you worked here for a year, you were at the factory...

when he went missing.

- I don't know. - Excuse me.

What's your name?

Alagh.

Alagh?

Tell me. If you know anything, no matter how small...

What are you doing over there?

Sir, so... Daehan Securities...

has an incredible program that I didn't tell you about yet.

So... Well...

You people are reporters, aren't you?

Get out. Get out right now!

Did you find out anything from that guy?

No.

I think the factory owner is suspicious.

He definitely seems to be hiding something.

Maybe it's because of the owner, but he won't talk.

My animal instincts tell me...

that it's the owner. He's the culprit.

It's not like I can get a warrant.

Hold on.

Hey.

Really?

Okay, be right there.

Let's head back for today.

Oh no!

I think I left my phone in the office.

Darn it.

- Your phone? - Yes.

You seem to be in a rush. Why don't you go ahead?

Do you mind? I'm really sorry.

It'll be a pain if my captain finds out.

It's okay. Go on.

Sorry.

- Bye. - Bye.

A predator needs no warrant.

Okay. Shall I figure out the truth...

about the factory owner?

You punk. Why don't you understand?

Hey. I'll tell you one last time,

so listen carefully.

That jerk went missing.

No one saw him since that day. Got that?

- Still... - Why you...

Look. I'm not the only one who will go down if things go wrong.

It'll be over for you too.

Think about your family back home.

Hey. Listen to me.

Why should we ruin our lives...

because of a jerk who killed himself?

Hong Jin Goo didn't kill himself.

- You are so... - Hong Jin Goo.

I've heard that name before.

(July 8, 2019)

(Hong Jin Goo, 42, male)

It's the man I killed. Why was that name mentioned?

Come on. You saw it too.

He died after writing the petition.

If not a suicide, then what is it?

Darn it.

You're wrong. Jin Goo didn't kill himself.

Why you...

To be honest, I'm chasing a serial killer.

March 4.

April 22 to 28.

September 13.

Don't kill me!

Does that remind you of anything?

I was digging my own grave.

The killer that Officer Shim is after...

It's me.

It's me.

(Boring Day)

Hello, I'm calling from...

the Seoul Department of Employment and Labor.

Is this Goseong Chemical?

I apologize for the late hour,

but could I speak to...

an employee of yours by the name of Alagh?

Who?

Nobody by that name works here.

It's Alagh. Alagh.

There's no one by that name.

There must be some mistake.

Out of your Mongolian employees...

Oh, we only have one Mongolian employee.

Is it Nergui you want?

Nergui?

Why do you want to talk to him at this hour?

Are you really a government employee?

I'll call back after I check the documents.

Nergui?

Alagh?

Alaghu.

Araghu.

(Crazy person...)

Aragh.

(Meanwhile...)

Alagh.

(Murder...)

(Hong Jin Goo, 42, male)

(Officer Shim)

The person you have called is unavailable right now.

Please leave a message...

Has he still not found his phone?

Going up.

(Psychopath Diary)

(We thank Yoon Ji On for his special appearance.)

After obtaining my journal,

Yook Dong Sik has been working with the police to solve my cases.

That means,

he doesn't know that the journal is mine yet.

Who on earth are you?

I am a predator that is on a completely different level.

A body has been found!

The suspect is a male in his 30s who is highly educated.

We suspect that he works in the financial world.

I must stop Officer Shim's investigation at all costs.
