Hey, Bong Yi.
I just sent you a photo.
Can you check if he's the doctor?
Ba Reum, it's him. He's the guy who did your surgery.
How did Han Seo Joon get to operate on my brain?
And why?

What's this?
(Episode 9)
(Photo)
"F" means female, "M" means male.
The numbers after the letter are...
the age of the victims.
Could the rest indicate the order in which they died?
The order of death.
(6: Joo Mi Hye, 7: Kim Hyun Sik)
Kim Hyun Sik was abducted before Joo Mi Hye though.
"Sex"?
What could that mean?
A punctured little finger.
A dot?
It's between S and E, X.
Could it be an abbreviation?
(Moojin Police Station)
"Serial numbering for animal testing."
"A system to identify tested animals."
"Mice that have been tested on..."
"are left with marks that involve the puncture of ears."
Ear tags or ear punches.
Experiments.
Test subjects.
(Test subjects)
"Subject of experiment"?
"S" as in subject and "EX" as in experiment.
They were test subjects.
Song Soo Jung, female, 25 years old,
and the 17th test subject.
They're test subjects.
Was the finger punctured instead of the ear then?
To people?
What did he experiment on humans?
It's impossible for brain damage...
to make you more sensitive to smell.
Although, there is one way that could happen.
If the olfactory bulb in the frontal lobe is replaced.
A frontal lobe...
- can be replaced? - What on earth...
did he do to the mouse's head?
If you let it live, you'll end up like that rat snake.
Is that what you want?
A nasty brain has been placed in this mouse.
"A nasty brain"?
You seem different. Compared to before, I mean.
Did you spend some time in a psychopath's brain?
What is this feeling?
That's why I've been remembering...
Sung Yo Han's memories.
Don't tell me...
you implanted Sung Yo Han's brain inside me.
Is that what you did?
You figured it out faster than expected...
which reduces the fun.
"Head Hunter."
About that nickname people gave me.
I actually quite like it.
So you took their heads after killing them to...
I even cut open the heads when they were still alive.
Everything was perfect.
Both the killings and my experiments.
I was on the verge of a major breakthrough...
until that young boy...
Die!
Wait. What's going on?
He was arrested for the murder of Woo Jae Pil.
The murder of Woo Jae Pil?
Hey. How could you end up doing this?
You moron. Why?
- You just threw your life away! - Calm down.
- Moo Chi! - Detective...
Hey!
Detective Kang!
Moo Chi...
My life came to this because of that boy.
Don't look at me like that.
I only took...
a few human heads to benefit mankind.
Every achievement requires minor sacrifices.
- Don't you agree? - "Minor sacrifices"?
That's what human life means to you?
Thanks to them,
you were able to survive your injury.
No, it's a lie!
What's going on? Detective Ko killed Woo Jae Pil?
We should talk outside.
He killed Woo Jae Pil to get to Han Seo Joon?
To be incarcerated in the same prison?
The possibility always worried me, but he eventually crossed the line.
That's why...
he kept pushing you away.
He was going to kill Han Seo Joon and become a murderer himself,
so he knew he couldn't...
Actually, he was determined to keep you out of it.
He made the decision...
on the day he was actually going to ask you out.
Your eyes will be bleeding at this rate.
Don't work yourself too hard.
Hey, your nose is bleeding.
You're like a student studying for his exam.
It's been three nights already.
I'll keep watch, so get some shut-eye.
Those sisters were raped and killed with a hammer.
Can you sleep when you think about their parents?
I will catch that louse and lock him up.
Hey. What is this?
What's your problem? Don't go through my things.
You plan to ask Ms. Choi out, don't you?
- No. - Whatever.
Anyone can see it in your eyes when you look at her.
Darn it. Is it obvious?
Very, very much.
When do you plan to do it?
Tomorrow. She's buying me dinner for helping her...
with her research.
I figure this is my chance.
But what if she says no?
To be honest, I'm crazy nervous.
Feel my heart.
Even murderers don't scare the mighty Moo Chi.
Wow. Love is powerful, isn't it?
Isn't her program on today?
No. We're on a stakeout.
Then you don't have to watch it.
(Death row inmate Han Seo Joon)
I have...
found peace in my heart.
I don't have nightmares anymore.
After confessing to the Lord and receiving forgiveness,
I feel completely at peace.
- I sleep well now too. - Hey.
Come... Come to think of it,
this will be recorded by the dash cam.
We'll be disciplined for slacking off.
Right. It's the anniversary of his mother's passing,
so he'll come.
He may be in the area,
so I'll make a lap.
Now,
I pray every day so that the families of my victims...
- can find peace... - "Peace"?
from the pain I've caused.
You sleep well now?
Although...
I'm still living in endless torment...
- He was a world-renown murderer. - and have nightmares every night.
- The Head Hunter... - You low life.
After confessing and asking for forgiveness,
- he has found peace... - Why are you still alive?
- Why won't they execute you? - How will the victim's families...
- be feeling about it? - Darn it.
Did the victims' families find peace as well?
We requested interviews from the victims' families, but...
If the nation won't do it, I will.
- We met Father Ko Moo Won, - I'll kill you myself.
and discovered...
- I'll kill you. - something unexpected.
Father Ko Moo Won, who studied theology at a later age...
submitted a petition requesting Han Seo Joon not be executed.
Forgiveness saved his life.
I'll let you go.
Go.
What?
Run away.
Don't do it. Don't kill him.
- Are you insane? - Let go.
Snap out of it. Get it together!
If you get in my way again, I'll kill you first.
You should've fired him.
Why did you take him to the Evidence Managing Team?
Why did you take him to a division that gets issued firearms?
You took him on purpose, right?
You knew he'd be like that,
and you used the poor kid, didn't you?
You wanted him to take revenge...
for your daughter, didn't you?
You freak. Stop it.
Don't take it out on him.
Darn it.
I'm sorry. He never drinks...
But he's upset about Moo Chi...
That poor kid.
(Visitation Questions)
Hello? I think he is in shock.
(30 plus years ago)
Well, it's CP. And the location of the hemorrhage must've been tricky.
But you did great work.
And the patient's current condition is good as well.
I understand she's a patient of Dr. Gary's?
Precisely. And 15 years ago, when she was 5 years old,
she was diagnosed with CP by Dr. Gary.
Well, you're in good hands now. We'll take very good care of you.
If you need anything, anything at all, don't hesitate to ask.
Are you the one reading this book?
Levodopa.
This is a dopamine deficiency supplement.
Who gave you this?
That's strange. Where did you get that?
There was only a man cleaning the rubbish bin.
A cleaner?
I agree, Dr. Planks.
It's extremely excessive and...
Do you know why the professor asked me to do the surgery...
that you were supposed to do?
Your patient Emma.
Nobody thinks she died by medical accident.
You killed her, didn't you?
What do you mean?
Dr. Gary is investigating.
It's not long before the mask you're wearing comes off.
You've noticed.
Was I too careless?
Should I give a real performance then?
You must not want to believe it.
Then why don't you go in person...
and see for yourself?
As you know, this patient was diagnosed...
as cerebral palsy by Dr. Gary at the age of five...
and has lived relying on a wheelchair.
From now on, I will show you a miraculous magic...
of this lady getting up.
Impossible.
This patient considered herself...
to have cerebral palsy for 15 years.
Wait.
Are you implying that I misdiagnosed?
That's right.
Misdiagnosis.
This patient is a rare disease patient...
with a lack of dopamine in the body...
due to GCH-1,
the mutation located in chromosome 14.
It's called "Segawa Syndrome".
"Segawa Syndrome"?
I saw a book in the patient's room.
The congenital CP patients also have...
intellectual disabilities.
But it wasn't shown from this patient.
The symptoms of CP had features that worsened...
in the afternoon.
Accordingly, I made the patient...
take levodopa pills three times a day...
to replenish the dopamine deficiency.
The results are as you can see.
Thank you, Seo Joon.
You gave me a new chance at life.
You're my savior.
I'm not the one you should be thankful to.
But him.
Daniel is in charge of that ward. He just got off.
Daniel.
- Daniel. - Jennifer.
What are you doing outside?
Daniel, I walked 400 steps today all by myself.
Gosh, great job.
The medicine is working nicely.
- Let's go and take your medicine. - Oh, by the way,
what happened to that patient?
The patient who's suffering from the same illness as me.
I've been secretly giving her this medicine.
I can't believe the doctors diagnosed her with cerebral palsy.
- Let's go inside. Careful. - Why don't you just tell them?
He's the one who identified...
that this patient had Segawa syndrome.
If it wasn't for him,
she would've been in a wheelchair...
for a lifetime.
Thanks to him, Gary, who was suspicious of me,
ended up leaving the hospital.
And after that, no one suspected me...
for the death of the patients.
Excuse me.
This is for you.
I don't have the ability to do anything else for you.
But there are tons of mice in my neighborhood.
Why are you giving me this?
I got a call from school.
They asked me if I'd like to study genetics there.
They're also going to let me get a degree there too.
It's all thanks to you.
Thank you.
I'm the one to thank you.
You were the best work of art that helped me...
hide my identity.
I have my own lab.
No one knows about it yet.
The moment you open that door, you'll be opening Pandora's box.
What kind of experiment are you doing with mice?
I'm doing brain implants.
- Really? - The brain...
is connected with a complicated neural circuit.
So it's impossible to access it.
And I'm trying to connect that complicated neural circuit.
I'm also looking for a way to prevent rejection...
once the transplant is complete.
But why are you doing this?
The brain only weighs 1.4kg.
But it contains the entire life of one human being.
It's interesting.
That means I have the power to control someone's life.
That's what you call a deity.
There's nothing special about being a deity.
"A deity"?
What about you? What's your dream?
Me? My dream...
is to find good genes.
I want to find good-natured genes...
so I can create a world without wars or crimes.
One of our researchers is Korean,
and he also wishes to create a utopia like that.
Why not just find bad genes?
If you find those who have genes with criminal instincts...
and prevent them from committing crimes,
you'll eventually be able to create a world with no crimes.
You're right.
Then I'll try to find a way to find bad genes.
Great. I hope we both get to achieve our dreams.
He said it was somewhere near here.
Are you ready?
Are you ready to face the truth?
After I killed Jennifer, I came back to Korea...
and became the best neurosurgeon.
I was enjoying my fame as a prestigious doctor,
and because of that, I had forgotten about my dream.
("Daniel Lee Successfully Detects Psychopathic Genes")
Daniel.
At least until that guy suddenly shook the entire world.
I only said it half-heartedly.
I couldn't believe he was trying to invade my realm of the divine.
This isn't good enough. It's not enough.
You haven't eaten, have you?
Would you like to eat some meat?
Meat? Sure.
Let's have grilled meat.
Let's go.
I needed brains.
Human brains.
You may enter now.
I wonder if something happened.
- Detective Ko! - Detective Ko!
How could you really commit murder?
- Please tell us! - What really happened?
- Tell us what happened! - Tell us!
- Detective Ko? - Tell us the truth!
(Execute the Head Hunter!)
(The house of a monster! The house of a murderer!)
Everything was perfect.
I was very close to perfecting the brain transplantation.
And I was also about to have...
a child of my own.
But one day, Daniel called and told me...
he'll be coming to Korea.
Wasn't it hard to adjust in the States?
It was very difficult to adjust.
He was nothing but a prop for my act.
I couldn't let someone so inferior...
take over the realm of the divine I've been dreaming to achieve.
I suddenly felt rushed.
I urgently needed to find a prey.
- Just one last experiment. - Do you know the way?
2, 3...
Three brains.
That was more than enough to carry out...
my last experiment.
Here we go.
How's the speed?
- Faster! - Where's the mineral spring?
See that over there? It's that way.
Please don't kill me.
Run! Get out of here!
Darn you!
Everything was perfect.
I killed nearly 20 people in the course of a year...
and made no mistakes whatsoever.
I thought the killings were perfect.
Mommy...
Just you wait, Han Seo Joon.
Detective Ko killed the suspect of the tie-knot case.
Fancy that.
You actually did it, kid.
I guess I should be waiting with a cleanly scrubbed neck.
I must talk to her.
I have something to say to her.
I must tell her something.
We said you can't.
How could you have operated on me though?
You're in prison.
The day after you were injured,
someone visited me.
I'm Officer Jung Ba Reum.
A very special someone.
I'm sure you remember me.
Of course, Officer Jung.
I was briefed on your reinstatement.
I'm glad to see you back at good health.
What brings you by here?
You must have something to say to me.
Join me.
This was your brain after the incident...
and this was Sung Yo Han's.
Your frontal lobe was severely damaged,
so Sung Yo Han's was harvested and then planted into yours.
How did you know that Han Seo Joon could transplant brains?
The day after you were injured,
I received a video tape by someone unknown.
Film in this direction and keep the camera still.
This video.
Where did you get it?
I'll ask you point-blank.
Were you successful?
Your son bashed another young man's brain.
The doctors say that the damage is beyond repair.
If the brain transplant can be done...
Then what?
I plan to gamble on it.
I never took you for someone this dangerous.
Why would you trust me to do the surgery?
It's not like you don't know who I am.
He'll die anyway if no measures are taken.
What do I get in return?
For doing the surgery...
No, for bringing him back to life.
What do I get in return?
Name your price.
Freedom.
Being locked up here for 30 years...
has made me stiff all over.
Truth be told,
letting a talented man like me rot behind bars...
can be considered as a waste of resources.
Don't you agree?
Fine, I'll bring him back to life.
Were strong security measures taken?
This ward has been closed off and can't be accessed...
by those without clearance.
It'll be over for us if word gets out.
Don't worry, ma'am.
A minimum number of staff members prepared the surgery,
but they weren't told what it was for.
You agreed to pardon him in exchange for saving my life?
No.
No? Why not?
I hear no president rejects your proposal.
I'm only the Chief Presidential Secretary.
Even if I had the authority to pardon you,
I wouldn't give in to your demand.
Fine.
We're done here.
Please.
Please...
Saving the honorable life of a young man...
is the only way you can atone for your sins.
The whole world is praying for him.
Please save Mr. Jung's life.
Atone for my sins?
An atonement?
Did you really believe saving me would do that for him?
Why did it have to be Sung Yo Han's brain though?
Transportation issues prevented us...
from using the brain we had prepared.
Just then,
we were told that Sung Yo Han died of respiratory arrest.
So with the consent of his father Han Seo Joon...
A criminal as a next-of-kin?
What you did is a crime!
I know it's an excuse,
but we couldn't turn our backs on the people's hopes.
No, you used me to stay in power.
If I die, it'll hurt your chances...
at the upcoming presidential election.
How you take this is up to you,
but I sincerely believed that...
I'd be letting the people down if we lost a young man like you.
If it weren't for her,
you would not be alive right now.
She got down on her knees...
and begged Han Seo Joon to do the surgery.
Can we let him leave like this?
- If he chooses to talk... - He won't be able to.
How could he tell the world...
that a piece of a killer's brain was planted in his head?
I'm curious about Han Seo Joon though.
Why do you think he suddenly changed his mind?
What do I need to atone for?
What's so wrong about a lion taking the lives of a few mice?
That's what he said.
But why did he change his mind about the surgery?
Where did you get this video?
It was sent to me by someone unknown.
I see you're still alive.
I noticed that his interview was edited out...
from the documentary.
I'm just really curious.
What could he have wanted to confirm?
Could it be...
No, there's no way he'd know.
I should've killed him back then.
Right then.
(Korea Correctional Service)
You will only get 10 minutes for your interview.
(Korea Correctional Service)
Yes.
It was her.
Park Hyun Soo.
So...
the reason she made that documentary...
was to kill me. Was that it?
How amusing.
Thanks to her documentary,
Ko Moo Won was murdered.
Ba Reum!
- Bong Yi. - What happened?
Sorry, something came up...
Did Mr. Moo Chi really kill that murder?
What do you mean? Detective Ko killed whom?
- Hey. - Ms. Choi.
What is this about Detective Ko killing Woo Jae Pil?
He turned himself in.
The officers at the scene gave consistent statements...
and he was holding the murder weapon when they arrived.
But something is suspicious.
What?
He had a gun, so why didn't he shoot?
Why did he use a scalpel?
Where's Woo Jae Pil's body?
There are no defense wounds.
You're bound to resist if someone attacks you.
So why did he not resist?
I sense rage in this wound.
If Detective Ko killed him, his motive would've been...
to go into the prison where Han Seo Joon is,
not rage toward Woo Jae Pil.
The neck wound is the deepest.
So he stabbed with the intent to kill.
It was overkill.
He kept wounding him even after he died.
The extreme rage made him lose self-control.
Detective Ko would've gone straight for the kill.
- Please sign here. - Okay.
The police took everything Detective Ko was in.
We want to see a different part.
What's this thing sparkling here?
Let's zoom in.
How... The hospital...
I can't make out the shape.
Hold on. It must've been caught by another camera.
I think I know who killed him. I need to go. Bye.
I'm going to go see my baby.
We're going to see our baby.
- Let's go see our baby. - Honey.
Hold on.
- Okay. - Well...
We're on our way to turn her in.
She'll be scared if you arrest her here.
I was selfish.
I wanted Moo Chi to kill the jerk who did that to my children.
I won't ask you to understand.
Where's your daughter's grave?
Goodness. What are you doing? Come out.
- What do you mean? - Shut it and come out.
If it weren't for Officer Jung...
Officer Jung?
That's right. He went to Inspector Park to catch the killer.
What? How did he know?
- What? - How did he know...
that Inspector Park's wife killed him?
She killed him?
Jung Man Ho!
Why are you crying at my daughter's grave?
This isn't your daughter.
What do you mean?
This girl buried here...
What do you mean?
She's my daughter.
My daughter.
My Soo Jin...
This man... Why is Jung Man Ho...
Two of the same hair ties...
that Park Hyun Soo was wearing when she was abducted...
by Han Seo Joon were found.
They ran a DNA test on the hair found on the hair tie...
which matched Park Hyun Soo's.
But as soon as Woo Jae Pil admitted to killing Park Hyun Soo,
Jung Man Ho, who was like a brother to him,
stabbed and killed him with extreme rage.
Why?
Why did Jung Man Ho...
kill Woo Jae Pil?
Why did he kill him?
I was reminded of my daughter.
You don't have a daughter.
What if he didn't lie and really had a daughter?
1994. Guryeong City.
There was a missing girl.
Hold on.
Here.
(Jung Soo Jin)
What are her parents' names?
She only had a dad. His name is Jung Man Ho.
My Soo Jin...
Soo Jin!
What are you doing?
So... Jae Pil is...
a murderer?
Soo Jin!
Daddy!
Why is that...
We have an emergency.
There's an armed assailant in the lobby of Moojin Hospital.
No, right?
My Soo Jin... It's not her, right?
Right?
Then...
why did the knife that they found in your house...
- have Soo Jin's necklace on it? - Daddy!
Why was that there?
Tell me.
Why are you closing your eyes? Open them.
Open your eyes and tell me.
Back then...
Please help me find my daughter.
- You helped me look for her. No. - Please help me find my daughter.
You were more desperate than I was to find her.
Here you go.
The police are searching for her, so we'll be able to find her soon.
I'll go hand these out over there.
Okay. Thanks.
You were more desperate than I was to find her.
So tell me.
Please tell me she's not my daughter.
Please. Please!
I'm sorry, Man Ho.
What?
Why are you sorry?
I felt guilty all my life.
Please believe me.
What?
What did you say, you jerk?
Die! Die!
Die!
Soo Jin!
(Moojin Bukbu Police Station)
- Sir, about your daughter... - Yes.
They're going to do a DNA test.
The results will tell me...
whether the girl in the grave is my daughter...
or Man Ho's.
Anyway, thank you.
No problem.
- By the way, - Yes?
how did you know Man Ho was the culprit?
Oh, well...
I found out by watching the CCTV footage.
Oh, I see.
- I'll see you. - Goodbye.
(Moojin Bukbu Police Station)
If I tell him I found this there,
then he might find out that I have Sung Yo Han's brain inside me.
(Main building)
Officer Jung.
Ms. Choi.
Thank you for finding the culprit.
But why are you thanking me?
Is it because Detective Ko got released?
I bet he resents me a lot right now.
I'll be off now.
Gosh, you look like a totally different person in a suit.
I tried to clean up nicely.
I'm having dinner tonight with my parents-in-law.
You're already calling them that when you're not even married yet?
You must be really happy.
By the way, about Mr. Kim...
I heard he didn't deserve to come to prison.
Everyone thinks that,
but there's nothing he can do.
The Supreme Court already reached a verdict.
There's a fight going on in building 3H28C.
- One of the inmates is... - 3H28C?
possessing a sharp weapon.
Patrol Team, please report to the area immediately.
Come here.
I told you not to take his side.
He's a jerk who killed 10 women. Why would you take his side?
Put that down. Put it down right now.
Calm... Calm down.
- Back away! - Hey!
Everyone in this prison knows...
that he didn't do it.
So stop bullying him!
You punk!
Get off me!
Let go of me!
- Get off me! - Stay still!
Thank you for finding the culprit.
I wonder if he really...
had feelings for her.
Gosh, that startled me.
Hey, Ba Reum.
You reek of alcohol.
I'm also as righteous as you are.
I'm a good guy.
Why did you drink so much?
Did you fight with your fiancee again?
What happened? Did you get hurt?
You know the gangster...
I told you about?
Oh, that guy who keeps bullying Mr. Kim?
That gangster bullied Mr. Kim again,
and he ended up hurting another inmate who tried to stop him.
- Is it that person's blood? - Yes.
He got locked up for assault, but he's a good guy.
He was only trying to catch the guy who raped his daughter.
My gosh. Did he get badly hurt?
Thankfully, no.
But you see, despite his old age, Mr. Kim suddenly got up...
and attacked that gangster who was wielding a knife.
Do you know what I was doing?
I just stood still.
I was so scared.
I was sacred I might get hurt.
You're also human. It's natural...
Chi Kook wouldn't have been a coward like me.
Chi Kook.
Gosh, I'm late.
Why didn't you wake me up?
I'll see you.
Already? Okay.
Bye.
Gosh.
With the consent of the victim's family,
the police will collect the DNA directly from the grave...
and request the NFS for a DNA test.
Many people are eager to find out...
whether or not the buried corpse is really Victim A.
He was going to kill Han Seo Joon and become a murderer himself,
so he knew he couldn't...
Actually, he was determined to keep you out of it.
He made the decision...
on the day he was actually going to ask you out.
I'm sorry.
Why did you pretend like you didn't know anything...
when I asked you to help me find Han Seo Joon's son?
Were you worried I might harm your boyfriend?
If you cared about me even the slightest bit,
you never would've dated that murderer.
I'm sorry, Moo Chi.
Why did it have to be Sung Yo Han?
There are tons of other guys in this world.
But why him of all people?
What made you fall for him so much?
I saw a similarity.
A similarity? With whom?
We were very similar.
That's why I was attracted to him.
How exactly are you two similar?
Did you also kill someone like him?
Is that why you think you're similar?
Get lost. You're ruining my mood.
Don't touch me!
Don't you dare touch me!
(Dried pollack)
The culprit who killed Victim A,
who was also a suspect for the tie-knot murders,
turned out to be A's best friend.
The police are assuming that A was the one...
who murdered the culprit's daughter 26 years ago.
However, the police will investigate the exact motive for his murder...
and file for an arrest warrant.
You almost killed the guy.
Why would you do that to a friend?
"Friend"?
Why am I friends with the Head Hunter's son?
Whose son?
(Patient Name: Sung Yo Han)
No, don't.
- Let go. Let go of me! - Hey!
Do you have it worse than those people?
The bereaved families of your father's victims.
Even they endure the pain.
So live to prove them wrong.
Tell them that you're different from your father.
Hurry!
- Careful. - Gently.
We were running from a cult when its dog bit her.
Gosh, you're relentless.
- That hurts. - But not enough to kill you.
As if. People die from being bitten by dogs.
Wait, you look familiar.
Don't you remember me?
How can you not when I saved your life?
I'm Choi Hong Ju, the producer at OBN.
Thank you.
The culprit who killed Victim A,
a suspect for the tie knot murders, turned out to be A's friend...
- and not a police detective. - Hello.
Goodness. A job well done by the officer of the nation.
I heard you caught the killer.
Well, it wasn't exactly me, but...
Gosh, let me do that.
Don't be ridiculous.
This should be done by me, not the nation's son.
No, let me do that.
Excuse me.
The man living in the unit above us...
followed us home while swearing at my sister.
What if he actually made it into our house?
We already checked out your neighbor once,
but he insisted that he was at home.
Are you saying that I'm making this up?
No, of course not.
There are decent door cameras out these days.
How about you install a security camera?
We barely make do, so with what money?
We'll make sure to patrol the block more often.
Got it, Officer Jung?
Yes, we'll do our best...
to keep you safe.
Officer Jung, are you all right? What is it?
Please excuse me.
(Here's what you asked for. A photo of you in kindergarten.)
A photo of you in kindergarten.
Like I suspected, it wasn't me.
They aren't my memories,
but Sung Yo Han's.
(Pyeongan Precinct)
- Hello. - Hi.
Is Officer Jung Ba Reum here?
He didn't seem well,
so the boss told him to head home.
- Oh, I see. Thank you. - No problem.
A nasty brain has been placed in this mouse.
It might kill you too if you let it live.
"A nasty brain?"
Sung Yo Han's brain that's in my head...
Quiet.
Shut it!
Detective Ko, what are you doing here at this hour?
Darn you.
Who do you think you are?
Come on. How dare you?
- I see you got wasted. - Darn you.
You...
Who told you to catch the real killer?
You darn idiot.
Darn. When will the whining stop?
You childish fool.
What?
As if you know anything.
Have you seen your family die?
Have you seen your family die before your eyes?
This is all your fault,
Ko Moo Chi.
(Mouse)
The father's necklace...
and Bong Yi's grandmother's brooch were here.
But they were gone when I came back with Officer Nam.
Officer Jung, aren't you too lost in the theory...
that another was responsible for Sung Yo Han's killings?
The bones' congestion indicate that the victim was strangled.
Since when did you study medicine?
Darn jerk. I can't believe you forgot my wedding.
Darn. Why did I miss this?
It's extremely stable.
It's the work of an expert.
Someone else was behind it all along.
