Back then, I thought it was a dream.
A dream of seeing myself.
Sin.
It's Mom. Sin. Wake up.
How is Sin doing?
If Mr. Seo were to find out...
Sin must stop him.
He has to go back.
Young Hoon.
I'm right here.
Sin. Go to Seoul,
and protect Sin's rightful place.
I'll do as you say.
So don't be sad.
He'll take my place?
That's ridiculous.
But...
this is a robot?
Even if he looks like me, he'll be caught right away.
Because in the end,
he will be different from me.
Try acting like me all you want.
Once I wake up,
it'll all be over.
(Are You Human?)
The kill switch. I overheard.
To him, that's like death.
If you're really his mom,
please get rid of that horrible device.
- What is it? - Dr. Oh.
Sin's finger moved.
His finger moved? What do you...
Your son, Sin! He's moving now!
(Episode 21)
What are you staring at?
People.
I'm trying to understand them more.
You're surrounded by such terrible people.
Aren't you sick of people?
I want to understand you more.
What?
I need to know more about you, So Bong.
You need to know more about me? What do you mean?
If I watch humans' facial expressions,
I'll be able to read yours better.
But I don't know what your expression earlier means.
What were you thinking?
Just now?
Lies don't work on you anyway.
For a moment,
I wished you weren't a robot.
Why?
I'm a robot.
I know that.
If not a robot, what should I be?
Forget it. Get up. I need to go home.
Sin!
Sin.
Why...
Why... Why isn't he moving?
Look at this.
His finger... His finger really moved.
His pupils are responding, and his gag reflex is back.
He moved his hand voluntarily too.
He'll be able to wake up and express himself soon.
This is real, right?
It isn't a dream, right?
I was so afraid something would happen to you.
Thank you for waking up.
Thank you, Sin.
Thank you for waking up. Thank you.
I still can't believe it.
- I need to go back. - Sit back down.
You weren't the only one who saw it. We all saw it.
Please calm down.
He can't know any of this.
He would be just happy even if he knew.
No, So Bong can't find out.
She returned as his bodyguard.
And she asked me to remove the kill switch.
She knows about the kill switch?
Yes. They seemed closer than I thought.
If she finds out, she'd tell him about the kill switch.
Why?
Can't he know?
He has the right to know that cruel thing is in him.
Didn't you see him decide and act on his own?
What if he finds out and refuses to activate it?
If he remains near the real Sin after he wakes up,
it can get very dangerous.
It didn't even happen yet.
And what? The "real" Sin?
Is he a fake to you then?
Doesn't he matter at all?
There's only one real Sin anyway.
You really...
Sin's recovery is our top priority right now,
so let's not say anything.
We still need them until Sin is fully recovered anyway.
You're all insane.
Sure, this was insanity from the start.
Insane or not, don't tell either of them.
(Champion Gym)
Bye. See you tomorrow.
- Why are you coming in? - I should say hi.
I'm close with your dad.
He even slept on my lap last time.
Don't even think about seeing my dad for a while.
Nothing good will come of it.
Bye.
Why would nothing good come of seeing me?
What did you do wrong?
Why?
- Enjoy. - Thank you.
Don't you want any?
I don't drink much.
Yes, I'm sure.
You wouldn't like coffee in a hick town like this.
Anyway,
I heard you called off the wedding. Is that true?
Yes.
I ran out of the wedding.
My gosh. How do you say that...
like it's no big deal?
My gosh.
I saw So Bong was wearing her suit.
You didn't hire her, did you?
I did. She returned to work today.
She said she'll quit and left. Why...
Did you call her back?
Yes.
I can't trust anyone like I trust So Bong.
So Bong?
Why are you saying her name like that?
- Are you friends or something? - Yes, we're friends.
Very special friends.
You just called off your wedding.
Why are you friends? It's unsettling.
She used being friends as an excuse. See?
Yes. She isn't a woman in his eyes.
That's how he can be friends.
Hey. Why you little...
- Just sip on your drinks. - Okay.
Let me ask you something.
Do you...
not see So Bong as a woman?
Naturally, I see her as a woman.
Her gender is female.
What?
I'll go. So Bong told me not to see you for a while.
- What... - There we have it.
For him, it's friendship. For her, it's love.
She ran right over because he called off the wedding.
Talk about an unrequited love.
I'm craving soju.
So? You met with my dad?
I said you're my guard again, so don't worry.
Yes, sir.
- Hi. - Who was that?
Was it Mr. Nam?
Yes. I'm working for him again.
Purely as his guard.
Why does he need a guard?
He could even save the world alone.
Pardon?
How did you...
I went to the hospital and saw this.
I just couldn't believe it, so I recorded it.
I thought about it for days,
but my limited imagination can't figure it out.
I mean, he wrecked a car with his bare hands,
popped the tires, but his hands were still fine.
Normally, a person's hand would tear and bleed.
What's his deal?
Is he even human?
There's no use.
I knew you'd do this,
so I made a backup file already.
- Ms. Jo. - If you don't tell me,
I'll upload this video online,
and send it to media companies.
Everyone in the world will want to know.
Is that okay?
Fine. I have no choice.
What it is? Tell me.
Well...
Sin.
I thought you didn't go to work today.
I had to stop by somewhere.
What is it?
So Bong is going to be my bodyguard again.
I heard from Dr. Oh.
You went to my mom?
Why?
You missed the human Nam Sin?
Now,
I know what your relationship is with him.
After becoming friends with So Bong,
I can totally understand you.
To you, the human Nam Sin is a friend.
A friend who is always there.
Just like how So Bong wants to protect me as a friend,
you want to protect the human Nam Sin as well.
Right?
Don't you want to be friends with me?
I look exactly like the human Nam Sin.
Just kidding.
Regardless, thank you.
For what?
You brought me here.
Thanks to you, I experienced...
human life and made a friend.
I think I can do better here from now on.
And one day,
I'll become friends with you.
Because you're a good person I want to be friends with.
I guess you don't want to be my friend.
What about my big brother?
That's what the human Nam Sin calls you.
Think it over.
Why did you come here?
Let's go home.
Let's talk at home.
I'm not going.
I'll never go to that house.
Ye Na.
You're a smart kid. Why are you doing this?
The wedding is over.
- It's over with Sin. - Says who?
It isn't over with him. It will never be over.
You're testing my patience.
I don't know what I'll do to him!
You already did.
What do you mean?
Ye Na.
I heard everything.
You tried to kill Sin.
- What? - Don't you care about me?
I love him!
How could you do that?
It was to live!
It was so that you and I could live.
I've done...
all sorts of dirty things for the chairman.
He had his son do the nice things,
but he had me jump into the sewer.
Only because I know his dark secrets,
he's leaving us alone.
You saw before!
That old man will never trust me.
He'd kill me...
before he dies so that I don't get in Sin's way.
Unless I replace him as chairman,
I'm a dead man.
Dad.
Ye Na.
You know something about Sin, don't you?
He isn't normal right now, is he?
Tell me. That's the only way we can live.
I'm begging you.
Please tell me.
You did this to yourself.
Ye Na.
You didn't have to do the dirty acts.
You did it because you wanted something out of it!
You make excuses after trying to kill a person?
Shouldn't you be sorry and ashamed first?
You're disgusting.
Everything in your head is disgusting.
Ye Na definitely knows about Sin.
Follow her.
Is that so precious to you?
Do you want to kill him that quickly?
Stop being unreasonable.
When your son wakes up,
I'll take him with me.
We'll go far away,
and live in hiding like we did in the Czech Republic.
He's already accustomed to living in society.
He won't want to hide.
You insist on activating that?
You spent 20 years with him.
It's much longer than your real son.
Sin!
His... His finger moved.
No, right?
I imagined it, right?
It did move.
He's going to wake up soon.
Is that true?
Are you really waking up?
You can't tell anyone yet.
I won't.
I'll never.
When you wake up, don't forgive me.
Don't forgive my dad either.
I'll take the punishment for him.
I'll die if you tell me to.
She found out something she shouldn't have.
(Champion Gym)
Stop staring at me.
I'm not going anywhere.
I said I won't tell anyone.
It's not like...
anyone would believe me anyway.
Thank you.
It's the story of a lifetime,
but you gave it up.
I'm sure Mr. Nam will be really grateful too.
What? A robot?
To be honest, I still can't believe it.
But...
that's my curiosity as a journalist.
It's a different story with you.
You left the company because Mr. Seo scared you.
He sent you in there...
to find out Mr. Nam's real identity.
If he finds out you knew and kept it from him,
he won't forgive you.
But you went back...
even if you knew all that. Why?
You should be running away.
Why are you endangering yourself for a stupid robot?
He isn't a stupid robot.
What?
He doesn't just look like a person.
He's much better than me, and I'm a person.
He knows to hug someone who's sad...
and to save someone who's in danger.
He doesn't lie and abides by the rules.
He always keeps his promises too.
He's always honest and sincere.
He's warm and smiles a lot.
This is serious.
You're totally a woman in love with a man.
I am not.
Yes, you are.
You're totally blinded by love...
and taking on all this risk.
Friend, I'll be there soon.
Get ready, and come out.
Hear that? Friend.
He and I are friends.
I'm going to wash up.
Can't you give me a heads up before grabbing my hand?
Total sleep, 5 hours and 34 minutes.
REM sleep, 1 hour and 22 minutes.
Why couldn't you sleep?
This is serious.
You're totally a woman in love with a man.
If something is bothering you, tell me. We're friends.
That's right. We're friends.
What?
Why did you lie?
Aren't we friends? You don't want to be my friend?
What do you mean? That was an error on your part.
It was not.
I told Ji Young Hoon to be my friend too.
- What did he say? - He doesn't want to be my friend.
Even though he opened up to me after getting drunk.
He did?
What did he say?
It's a secret. I can't tell you that.
Fine. That's probably your rule.
What's his problem?
He mocked me for confusing you for a person.
Why? Does it hurt?
That's right. You can't feel pain.
Something must be wrong with my FT sensor.
I broke a car for a friend recently, you see.
That friend is too embarrassed to thank you outright.
What about your hand?
It's not serious. I'll ask Mom to take a look.
Hi. Let's go in.
Yes, Mom.
What's up with her? She isn't mad today.
What happens if you have a heart attack while driving?
The car may strike other cars or hit a pedestrian.
A driver's heart attack may cause serious accidents.
You may sit.
- Please continue. - Yes, sir.
As Ms. Oh said, if our M Car was connected...
to the driver's health monitor,
the instant the driver's heart fails, the car...
will drive itself to the nearest hospital.
The car will save people's lives.
We can adjust the oxygen level in the car...
to assist the driver's breathing.
It may detect blood pressure problems as well.
We can detect the driver's biorhythm...
to calculate stress levels too.
When it's low, it can play preferred music or videos.
When it's high, it can prevent the driver from driving.
M Car isn't just a self-driving car.
It cares for the driver's physical and mental health.
M Car can have another meaning. Medical Car.
We can call it Medicar for short.
That is a great approach.
I'll buy it first. Make it right now.
Every old person like me will rush to buy it.
Anyone who's concerned about their health,
regardless of age, will buy it.
Make it quickly.
Pitch it to the shareholders at next week's meeting.
Yes, sir.
It's nice seeing you work hard.
The team members look happy too.
Thank you, Young Hoon.
Thanks to your hard work,
he is finally becoming a decent human being.
Mr. Sin's abilities are showing their potentials now.
Don't loosen up just because he's working.
Keep him tight.
See you later.
Thanks, bro.
It's all thanks to you, bro.
Don't call me that.
I was just kidding. Are you angry?
Is something wrong?
The chairman praised you, but you looked guilty.
Go ahead. I need to discuss business with So Bong.
What is it?
You played a big part in Mr. Sin...
being accepted by the chairman.
I wanted to tell you that.
Are you going somewhere?
What's gotten into you?
I've gotten busy,
so I'll leave you to care for Mr. Sin on your own.
Please continue to be of strength to him.
Why are you suddenly doing this? Just how busy are you?
How did I do today?
You were great.
Chairman Nam seemed very pleased.
Even if I do it my way,
I'll make sure it doesn't hurt the human Nam Sin.
I'll make things better for him when he wakes up,
so don't worry.
Okay. Do everything as you please now.
Do you trust me?
Did you call me here to ask that?
I'll stop by later.
- The FT sensor became dull... - No!
Sorry?
Well...
There's a problem with the lab.
I'll call you when it's fixed. Don't come before then.
Bye.
What did you talk about?
There's a problem with her lab.
She said not to come until it's fixed.
Really?
I'll look into it.
- How? - I have my ways.
This is So Bong. May I ask you something?
Mr. Nam's hand is stiff.
When will the lab repairs be done?
The lab?
Did someone say it's broken?
What?
Dr. Oh said...
You played a big part in Mr. Sin...
being accepted by the chairman.
Please continue to be of strength to him.
The lab is fine, isn't it?
Something happened there, didn't it?
So Bong.
Mr. Ji and Dr. Oh are acting strange.
Why are you keeping us from there?
I'm going to go there right now.
Were you afraid I'd find out?
Did you hide the fact that the real Nam Sin woke up...
in case I'd tell Mr. Sin of that horrible thing?
- So Bong. - Are you afraid he'll run away?
He wouldn't run away because of his mom.
You speak of him as if he were a person.
You made him look like one and treated him like one.
Didn't you?
Don't tell him about the kill switch.
It's too late to turn back,
and it won't do any good if he finds out.
I wouldn't tell him even if you told me to.
I can't tell him something so cruel.
But call him and tell him that Nam Sin is waking up.
- What? - If it weren't for him,
you couldn't have gotten this far.
Don't make him a fool that gets played.
- Tell him yourself. - Hey.
Should I tell him...
about the kill switch?
Should I tell him...
about the kill switch?
Sin, it's Mom.
I need to tell you something.
Something happened yesterday.
You'll be happy to hear it too.
- Hi. - Where are you?
- What? - Why aren't you coming?
I'm in the bathroom.
I'll be right there.
How did you find me?
GPS?
This is the staircase. Why did you lie?
Just.
The human Nam Sin is waking up.
- What? - Mom just told me.
His pupil is responding, and his finger moved.
I see. That's great.
Why do you look like that?
Did something bad happen?
No. I'm fine.
I can read expressions like that.
Don't hide it. Tell me.
I'm not hiding anything.
You're lying.
Why are you lying again?
- So Bong. - Who are you...
to track me and read my mind?
GPS? Lie detector?
Doing that isn't real.
When I want to be alone, let me.
When I don't want to get caught, pretend not to know.
That's what you do if you really know me.
I'll go first.
Sorry.
I didn't mean to tell her...
This wouldn't have happened...
if you didn't pick up her call at all.
I told you to be careful.
How could you do this in just one day?
I never agreed to it.
You guys decided that on your own.
It's because I'm nervous.
Something may happen before Sin wakes up.
David.
You always thought from my position.
Why are you being like this?
Because I always did.
I thought you'd think of my position this time.
So I'm pleading with you one last time.
If you're going to dump him, dump him to me.
It's me, Mr. Chairman.
You need to know something.
I understand, so stop.
He really is my flesh and blood...
since he didn't die...
and is making a miraculous comeback.
Anyway,
about the kill switch.
That can never be activated.
We can't have...
something you and I worked on for decades be destroyed.
Do whatever it takes to stop her.
If not,
you'll be useless to me as well.
The test installation of the chip has been completed.
M Car now has a perfect anti-hacking system.
You closed at the price Mr. Nam requested, correct?
Yes.
It was tough to lowering the price at the last minute.
I heard...
you attended Driverless Car Team's meeting.
Another M Car. Medical Car.
What a great idea.
I never knew Mr. Nam...
was hiding such creativity and drive.
Even I never imagined...
he'd be able to do that much.
You still haven't found Ye Na?
She left her phone off,
so we can't track her.
Please wait a while longer.
(Champion Gym)
Who are you to track me...
and read my mind?
GPS? Lie detector?
Doing that isn't real.
I've lost my mind.
He doesn't know anything.
Maibo.
Why are you doing this too?
I thought you really disappeared.
The human Nam Sin is waking up.
Who cares about this stupid robot?
Sorry about earlier.
I won't track you ever again.
I'm sorry for not understanding.
I'm sorry I'm a robot.
Would it have been better if I were a person?
You said that before.
You wished I wasn't a robot.
What happens to me when the human Nam Sin wakes up?
Where should I be, and what should I do?
I'm a robot, so I need to be useful.
But I'll be useless to Mom then.
Why are you useless?
You're useful enough for me.
That's why I'm thankful.
You understand me.
That's why I want to understand you...
like a real human friend.
Who asked for that?
You're just you. You just have to be there.
I don't need anything. Don't disappear. Just stay here.
Why would I disappear?
I'm right here.
What are you doing?
- I'm not crying. - You want to cry.
I know.
Cry all you want, So Bong.
You're a robot.
But why does my heart hurt so much?
(Champion Gym)
(Are You Human?)
(Mr. Nam)
Are you sleeping already? Why aren't you picking up?
If you don't pick up, I have to track you via GPS.
But I won't...
since you may want to be alone.
She didn't say a word all weekend long.
What's wrong with her?
You shouldn't bother people when they're working out.
Go back in.
She didn't call.
We have to leave now to rehearse the presentation.
Get ready.
What's wrong? Is something wrong?
So Bong cried.
She said her heart hurt because of me.
She won't answer her phone, but I shouldn't track her.
What should I do?
I'm sure she needs time too.
I'm sure she'll call soon.
Exactly how long is "soon" to humans?
24 hours? Or 48 hours?
"Waiting" can't be measured in numbers.
It's until the other person feels better and returns.
Until she returns.
Is the shareholders meeting today, where he's giving...
that important presentation?
Yes. I'll be back soon.
Please look after Sin.
Don't worry.
Why are you drinking wine so early in the morning?
Because nothing is going right.
If Sin gives a great presentation,
it's over for me.
Ms. Seo turned on her phone.
We've located her.
Are you insane?
Do you really want to fight me?
Hey. So Bong.
Let her be.
See you later.
Have you lost your mind too?
If stopping her won't work,
it's best to let her go as far as she can.
That's not what this is about.
- You don't know anything. - I do too.
That crush whom my daughter...
insists that he's a friend.
It's not a friend like that.
Then what? What is it?
I don't know.
(Dad)
Jongno-gu, Cheongwon-dong.
I can find the exact address in no time.
Did you think I wouldn't find you?
Although your car is right there?
Which house is it?
Over there. It's Dr. Oh's house.
She let me stay since I had nowhere to go.
I saw you coming out of this house.
Why are you still lying to me?
What are you hiding in there?
Nothing.
It's just because...
I didn't want you to know where Dr. Oh lives.
Let's go in.
- Dad. - If you stop me now,
I don't know what I'll do to you.
Don't make me become any crueler.
Let go.
What you want isn't in there.
It's at the office.
What do you mean by that?
What is that?
Young Hoon.
Wouldn't the chairman want to see the rehearsal?
I'll bring him.
Wait inside.
My son. It's good to see you.
It's nicer to see you outside.
What brings you here?
Is Nam Sin doing well?
Why are you worrying about that punk?
He's doing overly well, so don't worry.
Why are you annoyed?
Is something wrong?
Well,
there's something you need to know.
Go ahead.
Yes, ma'am.
Please. I'm begging you.
Get rid of the kill switch.
I'll make sure he doesn't hurt you...
or the Mr. Nam in bed.
Don't do this.
I'll tell everyone...
about everything I saw and everything I know.
I'll expose everything.
People will be shocked that a robot replaced a person.
That will...
only speed up activating the kill switch...
since I'll have to prove no such robot exists.
- Dr. Oh. - I'm telling you to stay out of it.
It won't change anything.
Sin will wake up,
and everything will go back to where they belong.
Not everything.
Since he'll be gone from this world.
Is this why you created him?
He disgusted me at first, but even I care for him now.
How could his mom of 20 years be so cold?
Is this why you started this?
Did you plan to dump him after making him comfort you?
That's not a real mom.
That's just a disgustingly self-centered human.
Criticize me all you want...
because I know I can't be a mom to them both.
(Proposed idea)
I haven't seen him that focused...
in a very long time.
You asked me, right?
You asked me what I meant...
by telling you not to disappear.
I'll tell you, so let's go.
You can't be here.
You always do as I say.
If you want to stay by my side, let's go.
I want to do that with you.
I don't want you to disappear.
Why?
Because I like you.
I like you.
I just like you. I like you unconditionally.
So don't stay with these people. Go with me.
I like you.
Let's go!
Mr. Nam!
Are you going somewhere?
We need to talk.
Mr. Nam. You are incredible.
You almost had me fooled.
Your mother...
is Dr. Oh up there, right?
She is your mother,
but she didn't give birth to you.
She built you.
Mr. Seo.
What do you think you're doing?
Stay quiet.
Do you think you can hide this?
I know everything, so you're done with.
We didn't hide anything. Stop this nonsense.
Mr. Park!
You're Korea's top AI researcher.
Even still,
I never expected you to create a monster like this.
If you made a young Sin,
you could've easily made an adult version.
Answer me, doctor.
Is that really a human being?
That monster sitting there isn't real.
It's a robot that looks just like Mr. Nam!
Okay. Now, will you...
still insist you're a human with flesh and blood?
We need to go.
Let's go!
What's wrong?
Blood...
Why are you...
Have you never seen a person bleed before?
You like me?
Who do you think you are?
(Are You Human?)
Did you really consider that thing to be your son?
Bring me that.
You look just like a human.
Don't go anywhere.
You're not my friend anymore because I like you now.
I can feel your heart.
