(Episode 10. Though Memories Fade, feat. How to Forget Bad Memories)
Okay, then.
Think of the appearance...
of the culprit who walked past smelling of a swimming pool.
On the back of his hand.
There's blood.
And...
There's a scar.
The smell of a pool.
The scar on the back of the hand.
The killer's the younger brother...
Kim Ho Young.
Hello?
Hello, is this Ho Young?
I am Geum Myung Se, the detective in charge of your mother's case.
We discovered a new clue regarding your mother's case.
Okay, what is it?
Well...
We should talk in person.
Where are you now?
At the swimming pool.
My gosh, it's getting late. You're still training?
When will you be done? I'll come and pick you up.
No, that's...
Goodness. High schoolers these days are such brats.
Hey, I'm a police detective.
How could you lie to me?
I'm sorry.
It just felt like a hassle.
Right, I get it.
It must feel like such a nuisance.
Oh, right. Have you eaten yet?
I know you have no one looking after you now,
but make sure you eat well. You're still growing, you know?
That way, your mother up above won't worry so much.
Let's go.
Let's have a bowl of noodles. It'll warm you up.
We'll eat first, then talk.
Can I go inside quickly and get changed?
Let's just go. I'm a busy man.
Then let me just drop off my bag.
Why?
Is there something important inside?
I guess there is.
There's something.
Hey, Kim Ho Young!
Kim Ho Young! Stop!
Hey, stop!
Kim Ho Young! Stop right there!
Hey, Kim Ho Young!
Hey...
That punk. Why is he so fast?
Hey.
Are you all right? Hey.
Ye Jun!
Ye Jun, no!
Thank you.
It's all good. Please calm down.
Thank you so much, seriously.
Please calm down.
Thank you so much.
No problem. Gosh, it must've given you such a scare.
Where did this punk go?
Shoot.
Darn it.
I've confirmed that he went this way.
We're analyzing the security footage to figure out where he went.
You're incompetent.
We would've caught him had I tagged along.
I lost him because I had to help the lady with the stroller.
You should've caught him before that.
You're a cop, yet you can't even run.
Look, Dr. Brain. You didn't see him run.
Don't even get me started.
He can run as fast as Usain Bolt.
I thought he was a swimmer, not a sprinter.
Either way, he is an athlete!
An energetic teenager at that!
I would've caught him, no matter how energetic or fast he was.
That's enough.
Drop it, you two.
Dr. Brain, you have the perfect mindset to be a competent cop.
What do you say? How about you quit your brain research...
and join the force?
No, thanks.
I thought your enthusiasm was what was keeping you here.
Oh, right. Let me make this one thing clear.
I'm helping out with this case as a consultant...
on the condition that Detective Geum donates his brain...
We got a call from the credit card company.
A transaction was made using Choi Jung Yoon's credit card.
I'm certain that her son, Kim Ho Young, is using her card.
Nice.
I've confirmed that he bought cup noodles, two giant sausages,
and a beverage here. He also took out a cash advance.
I thought Captain Seul had already verified that.
Keep listening.
That part-timer saw where he went.
Let's go to Motel Rose.
Last night, a young guy came in, wearing his hood like this.
He checked in alone.
Is he still here?
Well...
Yes.
What? She said she didn't see him leaving.
Is it not this room?
It is this room.
The cup noodles and the giant sausages.
Exactly what Kim Ho Young bought at the convenience store.
I think he stepped out for a moment.
I guess we're going on another stakeout.
I thought you were asleep.
Why are you so quiet? This is very unlike you.
Gosh, my chest feels heavy.
My traumatic memories are coming back again.
Trauma?
That does not suit you.
What is it?
Forget it.
Talking about it will only make me more depressed.
I could teach you how to erase painful memories.
Does such a thing exist?
Right. You do seem like someone who'd know of a way.
Then, tell me.
I can't tell you for free.
Forget it, then.
What the... Fine, it'll be on the house.
Only three people know about this incident.
It was about 10 years ago. A rapist with 13 convictions...
struck again...
right after being released from prison.
We found out that he was hiding at a motel,
and we were waiting for him in the parking lot.
(10 years ago)
When was the last time you went home?
Your wife must be worried.
That's the life of a detective's wife.
I told her to go to her parents' place.
Darn it. We need to catch him already.
This is exhausting,
and I miss my daughter like crazy.
How old is she now?
She's six.
I call her a pie. Sweetie-pie.
- Do you want to see a photo? - Sure.
What is it?
- What's wrong? - Maybe next time.
- Why? - I'll get going.
- Go where? - I'm not feeling it today.
- Hold on. - What the... What is it?
Stay like this for a little while.
What's going on?
It's nothing, so just stay in that position.
Why you...
Darn it. What do you think you're doing?
I want to get going.
When we're already here?
I'm tired, that's all.
Let's talk inside.
Detective Geum.
Detective Geum!
There's nothing wrong...
- What is it? - Honey.
Honey?
Why you...
Detective Geum.
- Please hold back. - Let go.
- Who are you, you punk? - Detective Geum!
- No, don't. - Let go of me!
Please don't.
My memories are a little fuzzy after that,
but I saw red...
and crushed his car.
Good for you.
A compliment from you is a first.
I'm one to compliment those who deserve it.
I would've been prouder of you had you crushed the jerk as well.
What happened to him?
They were discussing whether to go inside the motel.
Nothing happened, so he claimed that it wasn't an affair.
He had the audacity to say...
that I should pay for the damage to his car.
Don't tell me you gave in to his request.
Not even the biggest pushover would give in to that.
I said he should sue me...
and that I'd rather go to prison for what I did.
That intimidated him, and he backed off.
Ever since then, motel neon signs...
have been making me sick in the stomach.
Of course. I can see why.
Do you perhaps have an equally nauseating memory?
- I don't. - I see.
Your life must've been full of rainbows and butterflies.
As if.
I lost both my parents at the age of six.
Right. Sorry.
I just control myself in a way...
so that I'm not impacted by negative memories.
It's foolish to let past memories hold you back.
No way. Is such a thing possible?
I'm impressed. You truly are impressive.
What's your secret?
Wait. You said you'd teach me how to erase painful memories.
Is it a memory you actually wish to erase?
Of course.
I'd let you open my skull if it were possible to erase it.
We have an emergency. The suspect, Kim Ho Young,
is attempting suicide on the roof of the motel.
- What's going on? - What is this?
He should come back down.
He should think of his parents.
- My gosh. - What if he jumps?
(Hotel)
- This is too dangerous. - What if he jumps?
- Oh, no. - I feel terrible for him.
What could be going on?
(Hotel Cafe)
Kim Ho Young!
Kim Ho Young.
Don't come near me. If you do, I'll jump!
Okay, fine. I hear you,
so let's stick to talking.
Cut the nonsense and get lost.
You little brat. That's no way to talk to a grownup.
Okay, fine. You do the talking if you don't want to listen.
I'm sure you have something to say. Don't you?
Get back down here.
Come down from there so we can hear you out.
Won't you feel wronged to leave this earth...
without speaking your mind?
I'm sure you had a good reason.
What about your brother? His name should at least be cleared.
Do you know what he first does...
after his memory resets every 30 minutes?
He always asks how you're doing.
Don't you feel bad for him when he still cares for you...
after everything that has happened?
Don't talk about that jerk!
Dr. Brain, no!
You might not be high enough.
I'll ask you this question only once,
so think carefully before you answer.
Do you really want to die?
I do.
Can you handle what you just said?
If you can,
I'll make your wish come true.
Dr. Brain!
Consider that you just died and go live your life again.
- Are you all right? - I'm fine.
Please treat the kid.
What on earth was that? Are you all right? Were you injured?
- Must you be excessive? - Speak for yourself!
Are you out of your mind? Why did you do that?
Do you have many lives to spare?
I did it knowing I wouldn't die.
I'm not as reckless as you, you know.
Even with the inflatable mattress, it was still risky!
Why are you yelling at me when you weren't the one taking the risk?
Anyway, keep it down and help clean this up.
What the...
That darn jerk. Who does he think he is?
(Seobu Police Station)
(Interrogation Room 1)
This way, please.
Joon Young.
Ho Young.
Why are you here?
Joon Young...
Ho Young.
Why is my brother here?
Your brother was arrested as your mother's murder suspect.
What?
What is she saying?
It was really you?
Let's go.
We should go too.
Come along.
Ho Young.
Ho Young!
(Interrogation Room 2)
Calm down, Mr. Kim.
Let go of me!
My brother didn't do it. Ho Young!
We must go.
Ho Young!
Mr. Kim!
(Interrogation Room 1)
Relax.
Let's go.
Why did you do it?
Why did you kill your mom?
I didn't mean to hurt Mom.
I meant to kill myself.
I wanted to...
escape her.
She was a monster.
Mom knew that...
Joon Young kept forgetting.
When Dad or someone else was around,
she'd pretend to be a good mom.
She actually abused Joon Young.
He was so sweet.
His last memory.
Him being scolded for not swimming, that was my fault.
I whined about not wanting to go.
That's why we skipped practice.
Joon Young said he'd talked me into skipping...
and got scolded instead.
You're older. You should act your age.
If he wanted to skip,
you should've talked him into going.
Instead, you talked him into...
skipping a lesson?
If you want to quit swimming, quit yourself.
Don't talk Ho Young into slacking off too!
How dare you?
Move your hands.
You dare disobey?
After that,
Joon Young said he had a headache.
Then he started acting weird.
Mom knew.
She didn't get him any help?
She feared he'd regain his memory.
If he remembered what happened,
her abuse would come to light.
It started off as typical child abuse.
He stayed in his room...
because the headaches got bad.
Then he turned weird...
and became a reclusive loner.
What about your dad?
Did he not know?
Dad...
believed Mom.
That Joon Young was a reclusive loner and game addict.
He was always busy and rarely at home.
It's possible...
he was like me.
He knew and turned a blind eye.
I don't know.
I never talked about it with him.
Did the abuse get worse...
after your father died?
That's when...
Mom started to act weird.
She mixed...
cleaning solution into Joon Young's food.
I should've told her not to.
But I couldn't stop her.
All I could do...
Don't ever eat the food Mom gives you.
You'll die if you keep eating this.
- Why? - Just don't eat it!
Do as I say.
Eat only this.
Only what I give you.
Okay?
Do you understand?
He kept forgetting,
so I had to tell him every day,
but he seemed to remember what I'd said, which was odd.
That memory...
made him refuse the short rib soup.
You don't have much of an appetite?
No.
That's it.
Your brother liked bread and milk.
His memories were gone,
but his emotions remained.
I was worried about him.
When I got home,
Mom was screaming at him, telling him to eat.
I'd had enough.
I plucked up the courage to yell.
Will you stop it? You'll end up paying for this!
I'll pay?
How could you say that to your mom?
Who do you think I'm doing this for?
Why do you think I'm doing this?
I'm doing it for you.
If you're to have everything, he needs to go.
What?
Why do you think I married his dad...
and put up with the man so far?
It was for you.
So you could have it all.
I'm doing this for you.
If not for you,
I could go on pretending to be a good mom.
Don't use me as an excuse.
I spent the night...
at an internet cafe.
You're moving into a dorm tomorrow.
I don't want to.
Why not?
So you can feed your brother bread?
Mom.
You dare do this behind my back?
Think of the years I spent groveling for you.
My life wouldn't have...
become a mess if I hadn't gotten pregnant with you!
I wouldn't have had to turn so nasty!
That's when I thought...
I should die.
What?
You want to stab me?
No.
I'll kill myself.
You always blame me.
You said I made you unhappy...
and I was the reason you became a monster!
It'll be fine if I disappear.
You're just as immature as your father.
Fine.
Do it.
But...
if you want to kill yourself,
kill me first.
Let go!
- Let go! - Kill me!
Kill me first!
Let go!
The blood scared me,
and I ran off.
If she was cut in a skirmish,
it's not murder.
It's manslaughter.
One thing doesn't make sense.
If you wanted to die to escape your monstrous mom,
why did you frame your brother?
I didn't.
It wasn't me.
Are you saying Joon Young...
volunteered to take the fall for it?
Yes.
Ho Young, what happened?
Did you get into a fight with someone?
I killed that woman.
You don't remember anything.
Good for you.
In a few minutes, you'll forget everything you heard.
I wish...
I could forget everything too, like you.
I keep...
I keep thinking about what happened.
Ho Young.
Take this off and wash up.
Go wash up.
I'll take care of everything.
Ho Young.
[Kocowa Ver] KBS2 E10 'Brain Works' "Though Memories Fade, feat. How to Forget Bad Memories" -♥ Ruo Xi ♥-
I just...
lied down, tried not to think about it, and fell asleep.
Then cops showed up at our house.
I thought they'd arrest me,
but they said Joon Young turned himself in.
That was when I found out that he turned himself in...
to take the fall for what I did.
Hello, what is your emergency?
Police, right?
I killed that woman.
I'm the one who killed her.
When I heard that my brother had turned himself in,
I thought I might be able to get away with it.
So without even realizing it,
I pretended to know nothing.
I didn't frame him intentionally.
I really didn't know he'd turn himself in to take the fall for me.
Why did he do such a thing?
I don't get it.
Because of his memories.
When we were questioning him,
we asked him...
what his happiest memory was.
I was an only child.
My mom was ill, so I was always lonely.
Shortly after my mom passed away,
I met my stepmother and brother.
My stepmother was scary,
but I really adored my little brother.
He always listened to me.
We were like friends despite the age gap.
For the first time in my life,
I felt like I finally had someone on my side.
We took swimming lessons together.
One, two, three!
I felt the happiest when we were in the water together.
I didn't have to hear my stepmother's angry voice.
It felt like we were the only ones left in the world.
It was such a happy moment.
I think of that moment whenever I'm stressed out.
I feel at ease when I think of my brother.
Your brother volunteered to take the fall...
to protect the person who is so dear to him.
I'm relieved to know that...
he doesn't remember what happened.
No.
I'm sure he remembers.
You see, the human brain...
is wired to remember bad memories more easily.
Experiences accompanied by emotions...
such as intense anger or sadness...
are stored in the limbic system with special marks on them...
so that we could avoid such events if they were to occur again.
Your brother may not remember the actual incident,
but the traces of the horror, shock,
and sadness he felt at that moment are all stored in his brain.
And you were the one who left such traces on him.
Joon Young...
Joon Young.
(Restricted Area)
(Hopeful Corrections for a Better Tomorrow)
Mr. Kim Joon Young.
Who are you?
Police.
Until you get a designated guardian,
you will be under police protection.
Come with me.
Why do I have to be under police protection?
Mr. Kim, you have an amnestic disorder.
We are here to help you.
I have an amnestic disorder?
You'll find it helpful.
"I suffer from an amnestic disorder."
"I'm undergoing treatment at the moment."
"My brother will be here soon."
You're kind.
What's wrong?
Nothing.
"You're handsome. You're smart."
I've heard that many times,
but I've never had anyone tell me that I was kind.
You seem like a kind person.
Do you remember this guy?
No, it's just the feeling I get from him.
We have...
met before, right?
Yes.
(Patient Interview)
(What are your favorite things?)
All right. This is the last question.
What is your happiest memory?
Swimming underwater...
in the swimming pool with my little brother.
What's wrong?
No idea. I don't know.
Ho Young...
Where is my brother?
Don't you resent your brother?
Your stepmother abused you because of him.
No.
He suffered more than I did.
He always had to watch me suffer.
I envy you, Joon Young.
She's not your real mom.
My brother...
Where's Ho Young?
(Seobu Police Station)
You just sighed.
Why?
Are you depressed by how memories...
can make us powerless?
No.
I'm touched, that's all.
Reset Man.
Without his memories, he lives in a world of chaos.
But he still desperately tries to protect his brother.
It was like witnessing true love.
He's admirable.
I mean, humans are admirable.
I've made up my mind...
to give Yi Na many positive memories.
She'll know that I loved her dearly.
I may not be able to buy her a fancy house,
but I'll enrich her life with positive memories.
That is very ideal,
but you should think about making good memories with her too.
What?
Captain Seul.
Detective Geum has something to say.
This is so childish.
Excuse me, then.
People can see us here, so let's talk at the office.
Sure.
Just kill me already.
You want more time to think?
I can't believe you thought that was an appropriate answer.
I'm sorry.
This isn't something you should apologize for.
The atmosphere suggested that I apologize.
I'm sorry.
If you're not interested, just say so.
No, it's not like that.
My situation right now is a little complicated,
and I have a lot to consider.
Is it because you think I won't be a good stepmom?
To be honest, that is a thing I must consider.
Don't you worry.
As you know, I'm a little crazy in the head.
I can easily subdue self-centered brats.
You'll subdue her?
With love.
I can embrace her rebellious tendencies with love.
I'm saying that I can raise her with love.
Gosh, I'm not sure about this.
She's quite a handful.
Let me meet her, then.
I'm not sure about that.
Daughter, dinner's ready.
What the...
My gosh.
You could've tripped and fallen.
What is it? Is something up?
Why are the curtains drawn on your face?
What are you even looking at?
Is something wrong? If so, tell me about it.
Aren't you in the mood to lock eyes with me?
Daughter, can't you at least answer my questions?
Hey, are you even listening to me?
- I am. - What did I say? Repeat it back.
You talked.
No way.
They should never meet.
(Establish Law and Order That Put People First)
A patient with anterograde amnesia?
You witnessed a human being...
who stood powerless against his fading memories.
You seem like a kind person.
It was like witnessing true love.
He's admirable.
I mean, humans are admirable.
Actually,
I saw a man...
protecting a loved one despite his memory loss.
I was in awe...
of the capacity of the unstable but remarkable human brain.
Young man,
you are more sentimental than I gave you credit for.
You can call it my compassionate side.
Right, the compassionate Dr. Shin.
What could be...
the most intense memory you harbor?
Seeing a human brain for the first time.
I only felt one thing at the time.
I was entranced.
Then,
what could be...
your worst memory?
I'm not sure.
I read a news article...
about you losing your parents at a tender age.
That's right.
A car accident took them from me when I was six.
A car accident?
Yes.
Oh, dear.
How did it happen?
Were you also in the vehicle?
Yes, I was the sole survivor.
Then that must be your worst memory.
It's not.
I actually don't remember it.
All I remember is someone pounding on the door...
in order to rescue me.
It's the only memory I have.
Nothing else?
What happened right before the accident?
I don't remember that either.
How odd. A memory that intense...
usually traumatizes the brain.
The trauma must've led me to forget.
Don't you want to remember what happened?
No.
I believe in my own brain.
My brain must've erased that memory...
because it was more beneficial to my survival.
There's no reason for me to dig up that memory.
You will come across a reason to dig it up.
Hey, kid.
Kid!
What the...
Darn it.
"Hey, kid."
It isn't like you...
to mess up like that.
Tell me about it.
My mind jumped back to the car accident,
and I lost my concentration.
The car accident?
Yes, from when I was trapped in the car.
Why did you suddenly think of that?
Well...
I talked about it with someone today.
It must've stimulated my hippocampus and amygdala.
Speaking of...
The day of the accident.
Was it Director Park who got me out?
Could my memory have been distorted?
Why would you suddenly ask?
I remembered him calling out to me. "Kid."
That's what he said.
But there's no way Director Park would call me that.
He'd have said, "Ha Ru."
I'm not sure.
Could that be the distorted memory?
(Brain Hub Director Park Chi Gook)
Why did he suddenly remember that?
He said he talked about it with someone during the day.
You don't know whom he met?
I don't. I couldn't grill him.
He'd catch on.
Could it be...
Dr. Hwang?
It's not him. He promised never to meet.
I'll look into it, though.
Bye.
Hey, there. Gosh. Dr. Brain.
Goodness.
I told you to come early. What took you so long?
Why should I do as you say?
Can you not be like that?
You promised to tell me...
how to forget bad memories.
Oh, the motel incident?
Yes. Please get that out of my head.
(Hotel)
I asked you to erase it for me,
not remind me of it.
The first step to erasing a bad memory.
It's to get used to it through exposure.
Exposure makes it possible for a med student...
who fainted at his first autopsy...
to be able to eat intestine soup next to a corpse.
Now summon the bad memory.
- What's wrong? - I want to get going.
When we're already here?
Detective Geum.
The next step is what's important.
Activate the frontocortical.
Activating the frontocortical...
means viewing the memory as a third person,
objectively and rationally, minus the emotions.
View the memory in that manner.
You're witnessing a woman have an affair.
I'm tired, that's all.
- Let's talk inside. - No. I'm tired.
- We're already here. - Bye.
What do you think about the husband...
who didn't see this coming?
"What a moron."
"The pathetic fool."
That fool met his wife outside the motel.
As a spectator, what does this make you think?
"Seriously, he must be so angry."
- And? - "Darn angry."
I told you to be objective and rational and exclude emotions.
Oh, okay.
"He must be furious."
"But it's for the better."
Why is that?
If he hadn't seen what he did,
he'd have been led on for much longer.
The betrayal would be greater.
It was bound to come out one day.
What was bound to come out came out.
Whose loss is it if he keeps tormenting himself over it?
It's his loss.
The woman betrayed the man.
If he lets this trauma stop him from finding love,
whose loss is it?
It's his loss.
What you saw that day shook you,
but someone else asked you out.
Is that a good thing or a bad thing?
I don't know. Is it good?
It is. It's good.
What just happened? I think it helped.
Each time you remember that day,
if you think of it rationally,
the negative feeling will subside.
Turn bad memories into...
a valuable experience that aids your survival.
Turn bad memories into a valuable experience.
That sounds helpful.
Now, to turn the feeling of betrayal into a valuable experience,
what must you do?
"Are you free today?" No.
"Are you free this evening?"
No, darn it.
What am I doing? I'm not a teenager, but I'm like one.
Jeez.
(Neuroscientific Investigation Team)
What were you doing?
I was about to go inside.
- Are you going home? - Yes.
- See you tomorrow. - Yes.
Betrayal into a valuable experience.
Captain Seul!
How about dinner together?
Do that for me.
Laugh.
You have a weird laugh.
What? Oh, that?
I can't...
laugh like that out of the blue in this setting.
But if you want me to, I shall.
I think the food's finally going down.
Doing something I'm not used to doing...
is giving me indigestion.
Did I sound too old-fashioned?
Don't try too hard. We know each other's situation.
Right.
I said we should have soju at our regular place.
I can't take you there on our first date.
Have you...
decided to activate your love system?
No.
I don't need to make a huge decision out of it.
My love system was already activated.
A long time ago.
As a man who suffered a failed marriage,
I tried so hard...
to hide it because I didn't deserve you.
But I kept noticing you...
and wanting you.
Thank you so much...
for seeing that and making the first move.
Show yourself.
I don't think you took anything.
If you leave quietly, I'll let you off.
If you so much as swing that,
it'll get worse, and that would be no fun.
Dr. Brain?
He taught you that too?
Yes.
For me, love used to be a bad memory.
But he let me create a new memory over that.
Dr. Brain's a pretty nice guy.
Since Dr. Brain helped you create a new memory,
how about we create a thrilling memory?
What...
Oh, my.
What is this, all of a sudden?
Goodness. Isn't this too sudden?
Gosh, I'm sorry.
