The workers all went home,
so I'll need to do it.
I don't have anyone waiting for me at home...
or have children like you do.
I don't want to get married.
I just don't like people in general.
This job...
makes you hate people.
You know that too.
We get to see how far people can go...
when you work here.
I need to go.
Na Moo, where are you going?
Eat up. It's getting cold.
Eat.
You need to eat and regain your strength.
That way, you'll...
You'll get to see your brother.
And...
you need to get counseling too.
That's the only way...
I have no clue what to do either.
What is it?
I'll be back soon.
What?
(Police Station)
Look at you.
I told you people will point fingers at me if you don't look proper.
Are you looking down on me because I wasn't educated?
What about his meals?
Did you give him food before taking him around?
Why is he so skinny?
I'm sorry? Of course, I gave him food.
Are you really his mother?
He told me his biological mother passed away a long time ago.
He had two stepmoms...
Wait, was it three?
It doesn't matter if I'm 2nd or 3rd.
In any case, I'm his mother, and he's my child.
Na Moo,
are you going to come with me?
What is it?
Don't you want to come?
Are you mad at me?
Are you mad at me...
because we left...
without you?
I'm sorry.
I wronged you.
So please don't be mad.
I know you're a kind person.
All I did was yell at you...
and make you sad.
No matter how much So Jin bothered you,
you were still good to us.
So...
forgive me one more time.
Come with So Jin and me...
to a place far away, and live with us.
Well?
Is So Jin...
doing well?
Of course not.
She's always asking for you. She blames me for leaving you.
She's always crying, so her eyes are swollen.
So please think of So Jin,
and come with me.
Just consider me a stranger who makes food for you.
When you grow up...
and you think you had enough of me,
you can tell me off.
Just spit on me, and go on your way.
When that happens,
I won't say anything.
I promise.
Na Moo. What do you say?
Mother.
I...
can't go anymore.
Neither to So Jin...
nor you.
What?
(With the people...)
So...
you should just go.
Don't ever come back.
I'm...
fine.
There is something...
I promised So Jin.
Please tell her I'm so sorry...
for breaking my promise.
Please send her those words for me.
That's all I need.
Mister.
Please take me to the facilities.
What?
Hurry.
Okay.
No, Na Moo!
Don't go.
I don't care about that.
Do you think...
I wouldn't know what you're thinking?
So just come with me.
From now on,
I'll become your real mother.
I won't ever leave you behind again.
I won't ever let go of your hands.
Your mom...
will protect...
you.
No matter what happens,
I'll protect you forever.
Okay?
I'm so sorry.
I'm sorry, Na Moo.
So please come with me.
Please come with me,
Na Moo.
Mom...
I just don't like people in general.
This job...
makes you hate people.
Thank you for the food.
- Bye. - Thank you.
(Pork Soup)
(Clean and fresh, Cheonghwasu)
Hey, Do Jin. What are you doing?
Why are you working when you're hurt?
You have to work alone. I should help.
Just sit down.
I called you to make you food while you're on your break.
I didn't call you to work.
- I'm fine. - Forget it.
Do Jin.
Are you having a nice break?
Hello, Do Jin's mother.
Senior Inspector Ko.
"Hello"? Do you think you're on a children's show?
Do we look like we want to say, "hello"?
What were you doing when this happened to him?
Why do you let him get hurt all the time?
Mom.
It's not his fault.
I just...
missed him and wanted some pork soup.
Gosh. You're like a pine tree.
I always scold you, but you're always back.
Sit down. I'll give you a bowl.
Hey.
Why does your mother always yell at me?
Please sit down.
This was...
- delivered to Han Jae Yi? - Yes.
Her agent, Pyo Taek, will register the case tomorrow.
She'll request for personal guards.
As your boss, I decided to give this case to Jong Hyun.
Just ignore them when you see them tomorrow.
Got it?
(Actress Han Jae Yi Rushed to the Emergency)
Do Jin.
Give me...
- this case. - What?
- I can't do that. - The bloody hammer...
and the card written to Jae Yi's real name...
are signals targeted to the case 12 years ago.
- Please let me take it. - Forget it.
It could just be a stalker.
She's a famous person.
- Sir. - I already said no.
The one who hurt you is talking nonsense in jail.
We've been finding more weapons related to the recent attacks too.
It has bothered me long after you left.
No way.
Mister.
You told me something.
My dad's legacy.
That violence and hatred...
is not meant for me.
That I'm just related to my dad.
That in this world,
there's no such thing as tainted blood.
(Clean and fresh, Cheonghwasu)
Back then,
I swore to myself.
I swore...
to become strong.
Na Moo.
Now,
I'm no longer that kid.
I will become strong...
and...
protect everyone who protected me...
from the pain and suffering.
Hello. I'll be in charge of your case.
I'm Detective Chae Do Jin.
My beautiful...
paradise.
I know.
Detective Chae Do Jin.
Na Moo.
I can read Korean too.
But...
are you really the ace?
You don't look too fit.
I'm fine.
Forget about that.
Is this...
what you've received?
Yes.
Who sent it...
and why.
I want to know.
Nak Won. Get up.
Get up. Run away, please.
Nak Won.
Will you be okay...
if I take this case?
No.
I'm afraid that...
I'll end up taking you back into...
that nightmare.
Of course.
You're a cop.
We'll analyze the blood...
on the hammer first.
For the box and the card,
we'll check for DNA and fingerprints.
We'll collect and analyze security camera footages...
and contact the scattered crew...
and interview them.
It might take some time,
but we will find out...
who sent it...
and why.
We'll catch them and tell you.
I promise...
to protect you.
You don't have to.
I can protect myself.
So...
I hope...
you take care of yourself too.
Jae Yi, I think we should go.
The reporters posted photos of you too.
We released a statement refuting any relationships,
so you needn't worry about anything.
I'm not worried. It's an honor.
That day...
when I suddenly barged in,
were you very surprised?
You seemed more surprised than I was.
That day at least.
You spoke without a dialect.
You're speaking with one now.
I'll wait for your call.
This way.
Those people, really...
(Violent Crimes 1, 2)
What brought you here?
- Is something wrong? - No.
(Corridor security camera footage)
Han Jae Yi's past.
She's related to the victims of...
serial killer Yoon Hui Jae who was arrested in 2006.
The card mentions her name at the time, "Gil Nak Won",
and in the box was a hammer...
with which her parents were killed.
It was covered in blood.
The perpetrator is either someone who...
idolized the serial killings or a stalker.
We should provide police protection...
to prevent any secondary damages.
I agree with that.
Even if it's just a stalker,
the actions are beyond the scope of...
what we'd call normal.
Report back as soon as the NFS analyzes the blood.
- Yes, sir. - Hand out the smart watches.
- Yes, sir. - The guy in the cell.
He still won't talk as if he's still drugged.
I'll make him talk.
You have seven records,
and this time, you hid a criminal and inflicted grievous bodily harm.
According to Article 60 of the Narcotics Control Act,
unless you tell us who put you up to this,
you could get a longer sentence. Do you understand that?
No.
I don't however many times you tell me.
Park Sung Woo.
Don't you remember me?
"You're crazier than I heard."
You said that to me.
You lunatic.
You're crazier than I heard.
You mentioned a hammer...
and pretended to have carried out the random attacks.
The real attacker must've said...
he used a hammer.
Did you think I'd only use hammers?
What are you saying?
Do you think...
I look normal?
I live in a haze all day. I'm not myself.
May I lift that haze for you a bit?
I don't have...
much time to spare.
May I clear your head right now?
Darn you.
What cop acts like a thug?
Is this being taped? Is it, or is it not?
Why can't you blow his cover?
Who's the one...
who made you like this?
You made it, so why won't you use it?
Do drugs give you the courage?
Here.
I'll aim for you, so don't miss this time.
Do it properly.
You stabbed a cop already. Why are you hesitating?
Look into my eyes. Do you want to see it go in?
What?
You can't do it?
Do you need help?
Darn it.
Yes.
I know now.
I thought I had seen you somewhere,
and now, I know.
Yes.
Your smile looks...
exactly the same as his.
What?
If you get caught, you'll be the one to die.
- Do you understand? - I won't get caught.
There aren't any security cameras there.
And don't go after the crazy scum I told you about.
He's mine. Just take care of the rest...
so that I can watch him suffer.
Yes, that's right.
I can clearly...
see it now.
- Gosh. - Be careful.
- Oh, my. - What was that?
Gosh.
- Hello. - Hello.
Here.
- Look at this. - Okay.
Yoon Hyun Moo was released on parole at the end of last month.
He was probably a roommate at the prison.
He probably heard that I do anything for money.
I was just released,
so he must have heard it from the prison.
He wanted...
to hurt everyone around you.
Do Jin.
The second victim, Park Soo Chan, doesn't remember anything.
But the first victim, Lee Yoon Hee,
said that she remembers his shoes after we sent her the pictures.
These white sneakers.
(Additional Potential Suspects)
Act up one more time, and I'll really kill you.
These look like blood stains.
Were you in a fight again? Are you hurt?
No.
(Jong Hyun)
(Come out now.)
We can only guess as of now,
but the attack in the residential area,
the attack on Nam Gil,
and even on Han Jae Yi...
were probably his work.
He'd be using a burner phone, so I want you to find where he is.
All right.
(Family Members: Yoon Hui Jae, Chae Do Jin)
(Father: Yoon Hui Jae, Brother: Chae Do Jin)
It's my older brother.
When will the NFS give us the results?
It will...
come out tonight at best.
All right.
Be careful...
just in case.
Don't worry.
I was taught by the best.
I'm sorry.
(Gangnam Police Station)
Are you sure?
It's likely.
I'll visit you as soon as I get things organized.
You don't need to. Just send me the files.
And don't be so sure of yourself.
Investigate properly first.
Be careful, Do Jin.
(Han Jae Yi)
(Who Is the Man Han Jae Yi Met at the Hospital?)
So the victim, Cho Yeon Kyung, was screaming loudly,
so you killed her by accident while trying to quiet her with a pillow?
Yes, by mistake. I'm sorry.
Five years ago,
you raped and hurt a woman after making her lose consciousness...
by shoving a pillow on her face.
The situation was exactly the same.
There's a term in physics...
called "inertia". Have you heard of it?
- Sorry? - When something is not being...
affected by outside forces, it tends to maintain its status quo.
To put it plainly,
things that aren't moving tend to stay motionless,
and things that are moving...
try to keep moving.
It's the same with humans. If nobody is there to stop them,
they won't change easily.
What?
The victim has had...
thyroid operation a month ago...
and damaged her laryngeal nerve. This is the diagnosis...
from the hospital and the testimony saying she had lost her voice.
Your statement about how she was screaming so loudly...
- doesn't make any sense. - No.
She was screaming her lungs out.
You can save the excuses for court.
Sir.
Gosh, you scum.
(Han Jae Yi)
(Han Jae Yi Visits Police Station. Was She Threatened by a Stalker?)
- Well done. - Well done.
It's all done now.
Thank you.
(About PTSD Caused by Violent Crimes)
Someone must be getting married.
It's so easy nowadays.
She's desperate for attention.
She doesn't give up when she takes a bait.
Moo Won is going to press charges.
It can be seen as defamation.
Just wait a little.
It's fine.
Jae Yi.
The detective at Gangnam Police Station...
is the same person...
who stopped the reporters at the Police Academy,
isn't he?
He must have been closer to you before that.
Am I right?
Sir.
Whatever it is,
if something bad or difficult happens, tell me.
You know...
that is why I'm here, right?
Look.
You know that I'm this good, right?
I'm sorry...
for everything.
If I hadn't met Nak Won or Moo Won,
I'd never have become this person.
I'm sorry, and I'm grateful too.
That was a little strange.
I went to Gyeonggi Province to retrieve the product.
Gyeonggi Province?
Do you know where exactly?
Let me see.
It was Gowon-si.
It did feel a little strange while I was delivering it.
It was on some kind of a hill,
and the money was in an envelope.
Was it...
in Boyeon-dong, Yangin-gu, Gowon-si?
Yes, I think so.
Here's the address.
(The hill on 7th street, Boyeon-dong, Yangin-gu, Gowon-si)
