(and surroundings in this drama are fictitious.)
(Previously)
I almost had him.
But I blew it.
No. Catching him was impossible from the get-go.
Team Leader Hwang. Don't die just yet.
You're the hand with which I'll torture Oh Hyun Jae.
Oh Hyun Jae. You can never figure me out.
Mr. Bang's case was a private one.
Who would've known about the case?
Someone who he knew...
or worked closely with.
He's hiding amongst us, like a rat.
He's a police officer.
This organization you've been trying to save,
do you think it'll save you?
Take full responsibility for it.
If killing him myself is my only way to live,
then so be it.
Team Leader Hwang.
I think Detective Oh might be planning something dangerous.
Something is off.
I think he shared his intel with the team on purpose.
All right. Tell me.
Tell me who asked you to kill I Su.
(Restricted Area)
You... I'm going to catch you no matter what.
Make sure you catch him.
I see your shape.
But do you think you can find out about me?
Wait. We'll meet very soon.
Oh Hyun Jae. He saw The Guy's face.
Team Leader Hwang. How much do you know?
The Guy. I will get him first.
Kim Yo Han. I knew you'd be here.
I love this place.
Why? Because arresting me as a cop...
and throwing me in prison isn't your goal.
I Su, right?
Han I Su.
You want revenge.
Of course, I recognize her.
She started coming here around the end of November five years ago.
She always bought freesias.
Every year?
Oh Hyun Jae.
You're under arrest for killing Senior Chief Choi Hyung Pil.
Cha Su Young. So that's what you've seen.
Interesting.
Things were looking bad when you came,
but things are still looking bad when you're leaving.
Or perhaps, things were looking bad since you came.
Hwang Ha Young...
doesn't want me to get The Guy.
Hwang Ha Young.
What are you trying to hide?
(Episode 15: Trinity)
(The Trinity or when three are in a group)
Rubbing one's forehead is...
a sign of extreme discomfort.
She's making gestures...
to block out negative memories from her brain.
Ha Young, you're scared right now.
(Investigation Report)
Can I go now?
I might need you to come back,
but let's call it a day today.
Okay.
Bye.
Wait.
Yes?
I'm not sure if you'll remember since it was a long time ago.
5 years ago on November 29, you took a day off.
Do you remember what you did that day?
I can't even remember what I did a month ago.
What was the date?
November 29, 2015.
November 29...
I was with my friend.
We have been friends ever since we were kids.
A friend?
Can you tell me who that friend is?
I think you know him too.
I do?
Yes. He was my friend.
You blew up his head.
Don't you remember him?
Shin Gyeong Su.
Tell me just like that day.
"Spare me. Please spare me."
Spare me.
Please spare me.
Why won't you say it?
You were good at that.
Give me a name.
Don't worry.
I won't kill you today.
Today,
I'll let you live for...
the grand party I prepared for you guys.
No.
That can't be.
Kang Dong Sik...
is The Guy.
I must catch him.
Man Su.
Su Young.
Man Su is very busy right now,
so I'm answering his phone for him.
I'm very busy.
Can you tell me quickly why you called him?
Where are you now? Where are you?
Where are you?!
Do you want to see me that badly? Give me a second.
Are you... Are you harming Man Su?
(Mucheon Metropolitan Police)
I'll make it quick for him.
No. I'll go to you.
I'm going to you.
Where are you? Where are you, you crazy jerk?!
Su Young. Don't get so worked up.
Look up.
Call 911 now!
So this is the invitation I'm sending to you guys.
Team Leader Hwang.
Man Su.
They'll take him to the NFS.
Team Leader Hwang?
(National Forensic Service)
Will you give me a moment?
- Team Leader Hwang. - What?
When was the last time you slept?
Why are you pretending?
- Pretending what? - To be okay.
When you don't look okay.
Don't disappear again like you did...
five years ago.
You know that...
my phone is always on.
Gather round.
Ready? 1, 2, 3.
♫ Memories that have faded ♫
♫ I'm thinking of you ♫
Poor Man Su.
It must've hurt so much.
♫ Suddenly, ♫
♫ You've escaped from my eyes ♫
♫ I'm lost, ♫
♫ Trying to look for you alone ♫
♫ I'm leaving everything behind ♫
(Tell Me What You Saw)
(Miseok Goshiwon)
It was the same since I was a kid. I want to live an ordinary life.
Are you Detective Cha Su Young from the RIU?
Nice.
Hey. However busy you are, call your dad every now and then.
The whole neighborhood's worried about him.
You look after him for me.
Gosh. You're so shameless.
Why do you think I'm here?
- Hey. - What?
- In front of you. - What?
What?
Don't step on the poop.
- Hey, Dong Sik. / - Yes? (3 years ago, Hongwoon Patrol Division)
A rookie's joining today.
- Who? - The only person to come here...
would be Cha Su Young, right?
- Cha Su Young? - You know, the girl...
who kept coming by saying she'd become a cop.
Oh, I think I remember. Who is it?
My goodness.
Salute.
Constable Cha Su Young was sent to Hongwoon Patrol Division.
I hereby report for service. Salute.
I was right. It's Cha Su Young.
Nice to see you. I'm so pleased.
I'm impressed.
You'll get to protect Hongwoon.
I'm reporting for duty.
I'm Cha Su Young. I hope we get along.
Sure. Let's work hard together.
Come here. I got your seat ready.
I set up the computer and wiped the desk.
Say the name.
I Su.
Han I Su.
Why did you do it?
Why?
Why I Su?
If I'd said any other name,
would things have been...
any different right now?
I wanted to live.
The day I said I Su's name,
Hwang Ha Young died.
The moment Man Su died,
Hwang Ha Young the officer died too.
Even when I found out Kang Dong Sik was The Guy,
there was...
nothing...
I could do.
I was afraid.
Now,
there's nothing...
I can do.
Then die.
If there's really nothing you can do,
then it'll all be over.
Ha Young.
The most special person in my life gave me the greatest gift ever.
Thank you.
(Number withheld)
(Speaker)
(Oh Hyun Jae)
Detective Oh? It's me.
What's the matter? Is something wrong?
It's okay. Talk to me.
Who understands you as well as I do?
Hwang Ha Young.
The name you didn't say.
Hwang Ha Young.
The name I wanted to know.
The name...
you wanted to hear for the past five years...
is Hwang Ha Young.
I understand why you sound so down.
What'll you do now?
Hwang Ha Young. Will you kill her?
Or...
did you kill her already?
The fact that I know the name...
also means that you have no more reason to live.
No. That's not true, Detective Oh.
You may think that...
Hwang Ha Young is the final answer,
but she's just the beginning of another question.
Why did I choose Hwang Ha Young?
Why did she name Han I Su?
Aren't you curious?
Is that important?
It was just your game.
Good for you.
But...
that's just an answer worth half the grade.
The Detective Oh I know...
won't be satisfied with that.
Use your brain.
Don't just try to show off.
Find the answer worth full marks.
Are you curious?
Since when were we connected by a red thread?
Find me quick,
Detective Oh.
Don't worry.
I'll be standing behind you...
at the moment you least expect.
Sure.
I'll be waiting.
It's not your fault.
It is my fault.
I saw what I wanted to see.
I believed what I saw.
That guy...
That scumbag was next to me all this while,
and I smiled, talked,
and relied on him.
It's bad to be stupid.
I'm responsible.
Could you have stopped him if you suspected him?
Everyone has a story and a wound.
But we must judge everything based strictly on results.
And this result...
is my fault.
- Team Leader Hwang. - I will catch The Guy.
The Guy. Let's catch him together.
And make him stand trial.
Yes, Team Leader Hwang.
I met Oh Hyun Jae yesterday.
I think he will...
kill The Guy and then kill himself.
He'll leave me to decide what I'll do.
- Team Leader Hwang. - Don't worry.
I thought of something Man Su once said.
If you admit your fear and accept it,
you become a real detective.
I won't do anything to make him ashamed.
I'll save Hyun Jae too.
So will you trust and help me?
But...
you don't have to say all this to me.
Don't you just...
have to give an order like you do?
I don't want to lie to my people anymore.
I trust that,
Team Leader Hwang.
I trust you too.
Cha Su Young.
You'll make a great cop.
Someone unlike us.
A good cop.
(Corporal Kang Dong Sik)
Is this true? Is Kang Dong Sik really Peppermint Candy...
Team Leader Hwang.
Is Kang Dong Sik really Peppermint Candy?
This is great. I don't have to explain.
We're going after Kang Dong Sik.
And we'll make him stand trial.
Yes, we'll do anything.
But the higher-ups won't admit that Dong Sik is...
Peppermint Candy.
Then they'd basically be admitting that they were wrong.
How could you say that?
I'm just saying, we need to think.
One little mistake and they may prevent us from doing anything.
Don't worry, I have a plan to arrest Dong Sik.
Revealing who he is comes next.
You didn't even think to report to me about this beforehand?
What announcement is she making?
We don't know.
On March 11,
Section Chief Bang Sang Sik was murdered.
Two days ago, Senior Chief Choi Hyung Pil...
was murdered at National Forensic Service.
And yesterday, Detective Yang Man Su was murdered.
We have found critical evidence that proves...
that these three have been murdered by the same person.
The suspect, Mr. Kang,
with Section Chief Bang Sang Sik,
received bribery from moneylenders and abused his authority.
In the process of dividing the bribe money,
the two got into an argument that led him to kill Section Chief Bang.
It seems that Senior Chief Choi Hyung Pil...
and Detective Yang Man Su found out,
which led Mr. Kang to murder the two as well.
Section Chief Bang was originally found having committed suicide,
but Senior Chief Choi...
and Detective Yang were murdered using fishing lines.
That's the same way The Guy killed his victims.
Do you think this Mr. Kang may be The Guy himself?
We've been telling you every time,
but the official police response to the question is...
that The Guy died in a car accident five years ago.
Murders committed by fishing lines are merely a coincidence...
and we'll do our best...
to arrest Mr. Kang as soon as possible.
That concludes my announcement.
Checkmate.
That's a checkmate move.
Ha Young officially made...
the RIU her team as a move.
If she tries to assume that Dong Sik is The Guy...
and tries to arrest him based on this idea,
the higher-ups will stop her.
That's why she tied him with Section Chief Bang's bribery...
and then justified killing of the other two to cover up.
Not a bad move.
It's your turn now. What will you do, Yo Han?
Of course, you would've expected this.
But you only have one choice.
That's what you get...
for making this game so big.
What are you going to do?
Excuse me.
What brings you here?
Is this...
(Lawyer Jung Woo Sik)
How is Oh Hyun Jae?
I haven't heard from him.
Team Leader Hwang?
Kang Dong Sik is on the wanted list now.
Search warrants have been issued for Hongwoon Patrol Division...
and his home.
Let's go.
(Mucheon Metropolitan Police)
I'll call you when I arrive.
(Jung Woo Sik)
(Lawyer Jung Woo Sik)
Every little thing can be important, so please search thoroughly.
Yes, ma'am.
He wouldn't have left anything behind.
Most of his dishes and cutleries are disposable products,
meaning that he was prepared to flee...
as soon as the police caught on.
Team Leader Hwang.
(Oh Hyun Jae, Yeongwoon Metropolitan Police)
Yeongwoon is where Hyun Jae was first assigned.
It seems like The Guy has known Hyun Jae...
for much longer than we expected.
Perhaps even before he began murdering people.
Yes, Ji Min.
There's nothing much at Hongwoon Patrol Division.
All right, get going then.
(Mucheon Metropolitan Police)
Now that I think about it,
The Guy has been too obsessed with getting at Oh Hyun Jae.
Isn't it common...
for serial killers to be obsessed...
with getting at the detectives and profilers who are after them?
They see the detectives as their rivals.
But in this case, it's too much to just take it as a rivalry.
Perhaps there's another reason why.
Something between the two...
that we don't know about.
Yes. Something that not even Oh Hyun Jae is aware of.
Look for anything that ties Oh Hyun Jae and Kim Yo Han together.
- Yes, ma'am. - Yes, ma'am.
Ji Min, have you sat here ever since coming back?
No, I came back just now. Why?
Let's go.
The chair is angled differently.
Could it be...
(2020 Case Files)
Su Young.
Excuse me.
- Ji Min. - Yes?
Check your computer access history.
Yes, ma'am.
Detective Oh, where are you?
Did you know all along? The Guy...
About his plan.
What?
I just think,
why Mucheon Metropolitan Police?
Why did The Guy come to Mucheon Metropolitan Police?
Because it's the safest place?
No. It'd be even more of a dangerous place for him.
Because he's also...
on Ha Young's list.
He was going to be busted sooner or later.
He had another reason to do so.
A reason for him to come here.
The reason he's interested in Mucheon Metropolitan Police is...
because I'm there, exposed.
Try to recall what he said.
Su Young. Don't get so worked up.
Look up.
So this is the invitation I'm sending to you guys.
Invitation.
He called it an invitation.
Did he say anything odd?
Today, I'll let you live...
for the grand party I prepared for you guys.
A grand party...
that he prepared for us.
He came here to prepare for that.
Try to recall some more,
Cha Su Young.
(Joo Sa Gang)
Su Young.
Joo Sa Gang.
He was looking at Joo Sa Gang's files.
Team Leader Hwang, it's Joo Sa Gang's files.
Someone printed all of Joo Sa Gang's files.
(Printed)
But why Sa Gang?
Hyun Jae?
Hyun Jae!
It's not just the case files. It's also his mental assessments.
Even he couldn't play this game alone.
He needed an assistant.
Like Shin Gyeong Su and Dominic.
Yes. It would've been difficult for even The Guy...
to pull all this off in such a short period of time.
But Sa Gang is different.
He killed three members of the Sinwol Gang,
including his own father.
Sa Gang...
the left-handed serial killer.
(Mother: Joo Seon Hwa)
Team Leader Hwang! Sa Gang...
He's appearing before the prosecution today.
Contact the detention center and see when he'll be out.
This is Lee Ji Min of Mucheon Metropolitan Police.
When is Sa Gang appearing before the prosecution today?
Thank you.
- He just left. - We have to stop him.
- I'll ask them to stop him. - No.
RIU Team One will be taking the case exclusively.
(Ministry of Justice)
The Guy is after Sa Gang?
- Why? - I don't know.
The Guy and Sa Gang.
Ha Young and Hyun Jae.
If he's after Sa Gang,
Hyun Jae will be there as well.
Just bring Hyun Jae here.
Sorry?
But The Guy is...
We'll do whatever it takes to arrest The Guy...
and shut his mouth.
What's important right now is...
to shut Hyun Jae's mouth.
So, bring Hyun Jae here.
Yes, sir.
(Ministry of Justice)
(5 hours earlier)
I came because I heard that Lawyer Kim was here.
- Who are you? - Hello.
He's busy right now,
so I'm here as his replacement.
I'm Lawyer Jung Woo Sik.
I've said everything I needed to.
I think so as well.
I'll get going now.
It's not you that I want to talk to.
(Haewol-dong Serial Killer Case Report)
I want to talk to the other guy in you.
Hey you, left-handed.
Let's have a talk.
Stop. Don't do this.
Please don't.
Just follow Sa Gang closely until The Guy shows up.
He'll disappear if he sees anything suspicious.
Remember,
this is our last chance to get him.
- Yes, ma'am. - Yes, ma'am.
I'm left-handed
- Please move away. - Please get off the road.
Sorry, my engine isn't working.
- What? - Just get out of the way!
Sir, my work is complete.
Please, just get out of the way.
What?
Did Hyun Jae do this?
Back the cars up, please!
No!
Hyun Jae,
Deputy Park wants to have a talk.
(Ministry of Justice)
Gosh! Hyun Jae!
All right, Hyun Jae.
If I get there before you do, I'll have him waiting alive.
- Then that car was... - I'm sure.
It was Cho Bak Man, Hyun Jae's information source.
Hyun Jae must've...
come to the office while we were gone.
That's when he found out about everything.
Then why did he contact you?
To work with us to arrest The Guy?
No, he probably wanted Team Leader Hwang to come alone.
He knew that I'd tell her right away...
when I find out that his next target is Sa Gang.
But we found out first.
And to get us away from her,
he directed Bok Man to stall time.
Why did he want to get us away from her?
I think he believes...
that the three of them have something to sort out by themselves.
He was using you again. Can't you see?
No.
There must be...
a reason for sure.
I expected you to figure out my plan.
But you came faster than I thought.
What? Did you come here alone?
You think you can catch me alone?
My gosh. How disappointing.
Hwang Ha Young.
You must think I'm an easy target.
The weather is great today.
Perfect timing.
This is getting interesting.
In front of me, there's Hwang Ha Young.
In the back, there's Oh Hyun Jae.
You're a bit late, Detective Oh.
Why didn't you come on time?
You know what? I prepared...
a gift today.
Guess what this is.
Aren't you curious?
Do you see the transport vehicle over there?
I packed a gift in there.
A time bomb.
Won't that be fun?
I wonder how big the explosion will be.
If you stay near the bus, you'll get hurt.
I think you ought to run away.
But I don't think this is the right place...
to throw my last party.
Bye.
What? Are you going to shoot me?
If you do, you'll be in trouble.
Ha Young!
Go!
Hyun Jae.
I Su.
Hyun Jae. Hyun Jae.
I Su!
I Su.
Thank you.
(Domyeong Elementary School)
Domyeong Elementary School.
Hyun Jae, are you all right?
Where are you?
Okay.
Team Leader Hwang is at Domyeong Elementary School now.
"Domyeong Elementary School".
The school already closed down. It's not far from here.
But Domyeong Elementary School...
The Guy attended Domyeong Elementary School.
What is this? Why there of all places?
I doubt that he accidentally went in there on the run.
This might be a trap.
This gives me no choice. We must call for backup.
- Tae Sung. - I'm on it.
This is Detective Jang Tae Sung of RIU Team One.
Dispatch backup to Domyeong Elementary School now.
You're going to the scene? Where?
It's Domyeong Elementary School. It closed down 10 years ago.
RIU Team One...
is pursuing Kang Dong Sik who's a wanted man now.
RIU Team One is pursuing Kang Dong Sik?
Yes, sir.
Don't go to the scene now. Be on standby for now.
I'll send RIU Team Two.
But they requested our unit for backup.
Besides, Kang Dong Sik is...
Yes, sir. I understand.
You fools. Get your heads straight!
Your team outnumbered Oh Hyun Jae. How could you let him get away?
This is it now.
Do whatever it takes to silence those jerks,
Oh Hyun Jae and Kang Dong Sik.
- Do you understand? - Yes, sir.
What do you think about this place?
This is the last place I prepared...
for the party.
- The ambiance is nice here, right? - Kang Dong Sik.
It's over now.
Is it?
Why do you think I drag you guys all the way here?
I wanted to tell you guys...
that the world works in favor of people like me.
In this world,
there are too many people like me.
Just like them.
Do you know who they are?
They want to...
rip Oh Hyun Jae into pieces as much as I do.
So I invited them to my party.
Watch out. Or you'll be beaten to a pulp.
Hey, Kim Yo Han.
I need to sort something out with you.
It's starting once again. Let's see if you can avoid this.
Doesn't this bring back a lot of feelings?
Do you want to hear something entertaining?
A long time ago,
you gave me the wrong name.
But the name you gave me then will be the right answer now.
Tell me.
Name the person...
you want to kill.
The person you want to kill.
Tell me that name.
Now.
There's no one!
I don't want to kill anyone.
And no one will die at your hands. There's no one.
No one will die, Kang Dong Sik.
Even a scumbag like you will face the punishment of the law.
That will happen...
because I'm a cop.
Oh Hyun Jae!
(Tell Me What You Saw)
It's an order from your supervisor!
Starting this moment, you're off this case.
Shoot both of them as soon as you find them.
What is Detective Oh thinking?
Even so, there's no way he'd commit murder.
Detective Oh wants to put an end to this with him.
So no one gets in his way.
Darn it. This is madness!
The pain and despair you made the victims experience.
Before I make you experience that a thousand or a millionfold,
I will never kill you.
