Sin.
Are you okay?
Let's go home.
I won't go with you, so don't come back.
If you do, I will just die too.
It was the first time I ever lied.
Sin.
I did as I promised.
You won't do anything to my mommy, right?
I won't.
It was okay because it was for Mom.
I'm scared, Mommy.
Mommy.
No matter how scary it is, I can take it.
- Grandpa. - That's right.
I hit someone who is 100 times better than you...
because of you.
I'll keep doing that too.
Like you did today,
if you can't hold your temper and get into fights...
or gamble and do drugs...
like other people's crazy kids,
you won't pay for it.
Young Hoon will.
Good going.
He's just angry.
I'm fine, Sin.
I grew up well, Mom.
Move.
Let him do as he wants.
Regardless,
thank you for everything.
You're the one who broke your promise.
I said your mom would be safe...
in exchange for you being here.
Even if you finally find her and go to her,
your mom won't be there anymore...
since I'll find her before you do.
Go on. Do as you please.
My home...
is here.
At least until you die.
That's good.
I'm fine without you now, Mom.
(Episode 27)
- That's enough. Leave. - What?
I'm not interested in you, so leave.
What a jerk.
Life is pretty fun.
I think it'll cost more to silence the nurse.
Why did she have to recognize my face?
She knows for sure that Jung Woo didn't commit suicide.
Shut it.
Sin is in this house.
I'm sorry.
I was careless.
It's time to stop lying.
Just wait.
Something very amusing will happen soon.
I'll meet Mom and find out the truth.
Oh Laura. Don't you understand?
Laura Oh, in your format.
You said you knew this region. Why can't you find her?
To be honest,
I've been wanting to find you too, Mom.
But did you...
leave me and make that robot?
Without knowing anything...
about how I've lived?
No!
Sin.
Why are you turning around?
I'm the real Nam Sin.
I'm the real Sin!
A robot...
that looks like Sin?
I know exactly where Sin's mom was and what she did.
When I found out that she made a robot...
that looked just like Sin,
I created a foundation...
and sponsored her work.
HR Foundation, which sponsored the upgrades...
is me.
And Sin's mom has no idea.
Mr. Chairman. I'm sorry.
Everything is my fault.
I brought that robot to replace Sin after his accident.
Sin had nothing to do with it.
He didn't know anything.
It's okay, Young Hoon.
As you said,
I was always afraid someone would pass me.
If I can turn a robot that looks like a human...
into a product that I can market,
I thought...
that no company could catch up to PK.
But once I saw that robot,
I started having a strange thought.
What do you mean?
Who is appropriate to succeed me.
Sir.
How could you say that?
Sin woke up.
He's fully recovered.
How could you compare Sin and that robot?
Haven't you ever thought...
that the robot was better than humans?
Don't cry.
I'm fine.
Sin.
What? Do I scare you because of what I did?
No.
Nothing you do can scare me.
You must've been so stressed to have done that.
It breaks my heart.
Don't look at me like some wet puppy. Give me my phone.
Hi, Young Hoon.
Hi, Sin.
I can't stand him anymore.
I'm going back. I don't care if you get mad.
Let's do that.
- What? - Return to work tomorrow.
But we can't swap completely.
You're not fully recovered yet,
so let's have you take turns.
I'll pick you up tomorrow.
What did Mr. Ji say?
Did he let you go to work?
It's perfect.
I can't tell at all.
Mom fixed me well.
You took this, right?
Shall we give this stupid car to Nam Sin,
and walk?
Okay.
Why are you looking at me like that?
Are you upset that I broke your son?
Break him more...
if it makes you feel better.
I created him because I missed you.
You have every right to be offended.
I'll do anything to make you feel better.
Drop the act.
I know you're doing this for him.
Sin.
What must I do to get closer to you?
You show up after 20 years and say you're my mom.
Did you think I'd be happy?
Sin.
Please...
You'll do anything for me?
If you want to make me feel better,
wait another 20 years.
Just like I did for you.
Ye Na!
(Are You Human?)
The human Nam Sin must hate that I'm Nam Sin.
Would it be better if my name was different?
Why should you lose your name because of that jerk?
Your mom may have made you to replace that jerk,
but you were Nam Sin since day one,
and you still are.
What about your face?
Will you change your face too?
Even if you have the same face and name,
you're nothing like that jerk.
So don't be discouraged. Be confident.
Live with your name.
Nam Sin.
Okay.
Nam Sin. Confidently.
That's right. You have different names. I forgot.
You're just Nam Sin. He is "the jerk, Nam Sin."
I'll go now. Goodnight.
Okay. See you tomorrow.
(Champion Gym)
What? The chairman knows?
How did he...
Were we caught?
He knew everything...
but pretended not to.
It won't hurt him, so don't worry.
But why are you telling me this?
Because something is bugging me.
I can't tell what the chairman is thinking,
but even if Sin comes back,
I don't think he'll let that kid go.
That's absurd.
I agree.
We must get Sin to return to work as soon as possible.
I'll have them take turns until he adjusts.
Then...
I'll need your help.
Even if Sin comes,
please stay with him as you do now.
Why should I?
I detest that jerk.
You and I have the same objective.
I must protect Sin,
and you must protect that kid.
If you help me,
I'll help you all the way as well.
Are we going in together today?
No. Sin is going to the office today.
Sin?
The human Nam Sin?
He is returning for good?
I'm going to have him switch in and out to adjust.
The human Nam Sin hates me.
What if he hates what I did in his place?
That's for him to deal with.
We got this far thanks to you.
It'll be harder for a while,
but thank you.
Very much.
I'm so glad it ended up how you wanted.
Congratulations.
Stay at So Bong's gym today.
See you later.
That's right.
Good morning, Grandpa.
Did your mom send you?
No. I just came on my own today.
- Why? - Because I think I should...
come and greet you even if I'm scared.
What's wrong, Grandpa?
Did you cry again because you missed Mommy?
What?
Sin! How long will you cry for Mommy?
I told you not to be weak!
Why won't you listen to Grandpa?
Grandpa! I'm not Sin!
I'm Hee Dong! Hee Dong!
What's wrong? Was Grandpa being scary again?
He called me "Sin"...
and got mad at me.
You must've been surprised.
I brought you a gift, so cheer up.
A gift?
Go to my room this afternoon.
It'll protect you whenever you're scared.
Why did you come here?
Did you pretend to have dementia again?
Why did you call Hee Dong that?
That's right. I was pretending.
I pretended to have dementia again.
You're lying.
You really showed signs of dementia?
Let go.
What do you know?
Get out right now!
If you go around saying anything stupid,
I'll make you pay!
You need to calm down.
- Your blood pressure and pulse are high... - Let go!
If you don't want to get caught, be quiet.
I understand you're shocked,
but getting upset is bad for your health,
so take big breaths slowly.
I won't tell anyone, so don't worry.
But you must make a promise too.
Even if you're scared and don't want to admit it,
go to the hospital.
I'll take care of it,
so get out.
Hello, Mr. Nam.
- Why is she here? - I told you.
You'll have to take turns for the time being.
We need her to be with you to avoid suspicion.
Now, they'll both act arrogant about helping me.
She likes money, so use money to silence her...
so she doesn't complain later.
So Bong.
Thank you.
I'm at the gym, but you're not here.
I'm at the office.
Mr. Ji asked me to guard the human Nam Sin.
That jerk needs to adjust quickly for you to be free.
I told Dad, so make yourself comfortable.
I'll be home soon.
You don't have...
your usual super luxurious look today.
I heard the real heir showed up.
Yes. I had nowhere else to go.
Sin.
What are you looking at? Get out.
I'll come when it's time for the meeting.
What are you doing?
The blinds are closed. Are you looking for something?
I just wanted to be alone.
Here's the update on the M-Car.
Study it before the meeting.
Okay. You may go.
Where is it?
Did Mr. Kang's warm ups look this luxurious?
Even if you wear something like this,
you totally look like...
a sportswear model.
That's because he isn't human.
- What? - What?
I mean...
Gosh.
It's because he has long legs. That's why.
I see.
Anyway, he isn't an heir anymore as of today.
So you need to earn your keep.
What do you mean? He isn't an heir anymore?
Were you pushed out by a brother?
That's bad. You're the highest class person I know.
Start with this, okay?
Get that corner and that corner.
Clean up all the dust here...
and on the ceiling. Everything.
Darn it. You stupid...
Darn it.
I was wrong about you.
- You were all about money. - Right?
Now that he's no longer an heir,
- he's being mean to him. - I know, right?
- Shut it. - That's not right.
How could someone like him clean?
We may not complain,
but our backs hurt like crazy after cleaning there.
Go out later, and help him a little.
I'm done.
I'm done cleaning.
This is insane.
Did you call a cleaning crew behind our backs?
- At least you won't starve. - I don't need to eat.
I can do anything. Just say the word.
I can cook, do the dishes, and even do laundry.
My gosh. Then our boss...
will get arrested for violating human rights laws.
For abusing you like a slave.
Human rights?
- Give me a break. - It is human rights.
You're not treating him like a person...
just because he's no longer an heir.
It's robot rights.
- Mr. Kang! - Mr. Kang!
Gosh. Go pick up the pot.
Clean up in there too!
- Hello? - Hello, Mr. Nam. It's Dr. Lee.
I need to talk to you about the chairman.
Here.
Stop eating, will you?
Aren't we going to start?
I'm sorry. The Medical Car is going well.
The shareholders are favorable to it,
and the industry is very interested as well.
Seeing how competitors are dying to hurt it,
it'll be a big hit.
Once we get confirmation that it's safe,
we'll get a temporary permit.
What about the hacking problem?
Won't it be rejected if there's a security problem?
If the cyberattack prevention protocol passes,
we shouldn't have any problems.
It was of huge help because you analyzed...
the M-Car hacking situation.
- I did that? - Yes.
You'll put the documents together again, right?
With the abstracts and translations again too.
Thank you.
Let's get lunch together.
A new restaurant opened downstairs.
Gosh, it's so fancy-looking.
We'll never get to try it without his company card.
Are you here to play?
Put what together? Company card, what?
What do you take me for?
He switched characters again.
Mr. Nam.
- Do you have a split-personality? - What?
- Mr. Nam. Are you okay? - Let go.
I don't need your help.
(Episode 28)
The number you have dialed is not in service.
What's your problem?
Like it or not,
I'm your bodyguard right now.
Once you've calmed down,
I'll bring you to Dr. Oh's place.
Not there. I want to go home.
You can't go home like this.
You're my bodyguard.
You need to listen to your client.
I'll call Mr. Ji.
What are you doing?
You must be here for a reason.
You wouldn't be helping me for nothing.
If you want something, do your job.
Your job now is to put me back in my place.
You're sweating.
You're the real Mr. Nam.
Welcome back to the company.
As expected,
there's no fooling you.
You aren't even well. Why did you rush your return?
Is it...
because of what I said the other day?
Yes. I wanted to see if that thing is better than I am.
I had exaggerated on purpose when I said that.
Please don't be upset.
I was a bit extreme as well,
so don't mind me.
I'll see you again.
Do you think he'll really do something to you?
I threw bait, so I knew he'd come to bite.
He's just as emotional as his dad.
He hasn't changed at all.
Did you predict all of this?
He'll continue to act as I predicted.
The chairman is waiting.
He called for me?
He said you knew everything.
We'll have to see the blood test and MRI results,
but there's a high chance that it's dementia.
He's very traumatized,
so he's resting.
It's nice because you don't try to comfort me.
This is what I get for messing with my life...
for all these years.
I didn't tell anyone.
I know.
Because you keep your word.
How did you know I knew you had dementia?
That hand.
- My hand? - You can tell if someone is lying.
Do you...
know about me?
If you blink,
that means it's a lie.
Did Mom tell you?
Your mom doesn't know that I know.
Then it must've been David.
If you knew I had replaced the human Nam Sin,
then you must also know that he was in a coma.
Then why didn't you go see him?
I'm more interested in you...
rather than humans.
The human Nam Sin would be hurt to hear that.
Talk about yourself, not Sin.
How was it being here?
Don't you want to remain here?
Why do you ask?
This is the human Nam Sin's place.
So Bong is here, and so is your mom.
If that is what you decide,
you can have the company, the car, the people,
and everything you want.
You know I'm a robot.
Robots have no ambition.
Especially if it's taking from others.
What are you doing?
The blinds are closed. Are you looking for something?
I just wanted to be alone.
(Daekuk Long-term Care Hospital)
A long-term care hospital?
It's huge.
Sin gave this to you?
Yes.
Mommy, I think I understand why adults say they die.
I think...
I'm so happy that I could die.
What?
What are you doing?
Sin! Thank you for the gift.
I love it so much!
- Hey. - Sin.
What's wrong with you now?
You bought that for him, but you're still unhappy?
I bought him that hideous thing?
I must've lost my mind for a moment.
If you like it, take it, and get lost. I'm tired.
What? Get lost?
He isn't feeling well.
I think it would be best if you go for now.
Fine.
People die if they change too drastically.
Let's go, Hee Dong.
I don't mean to get involved,
but must you go this far?
If you're too different...
You want me to act like that thing?
I'll go now.
The human Nam Sin can't see me here.
Don't ever tell anyone...
that I have dementia.
Can't I even tell the human Nam Sin?
Of course not.
I'll keep my promise...
since that's the rule.
This is why...
I like you.
You are close to the perfect human...
that I've always imagined.
Don't deceive the human Nam Sin for too long.
It's unfair for me to know if he doesn't.
Why are you here?
Don't you feel sorry towards Hee Dong?
Do I need to?
You freak.
- No. - Move!
I'm going to see Dad.
You're always like that.
If anything doesn't go your way, you cry to Grandpa.
I had forgotten...
what a jerk you were.
Come out after a few minutes.
I told you to stay somewhere else.
Why were you in that room?
I can't tell you. Sorry.
You're not doing this on purpose, are you?
Listen.
I detest this house, but I hate seeing you here more.
I was your substitute, but this was my home too.
- What? - And don't be mean to Hee Dong.
He's still a kid.
I don't care about this family.
So Bong, whom you cherish the most, is by my side.
She's here? So Bong is here?
That's right. Next to me. In my room.
People should be with people. Don't you agree?
You can't say anything at the mention of So Bong.
Should I pretend to be you and mess with her?
Should I hold her hand and kiss her?
When did you get back?
Give me a break.
Why did you come here?
I can't tell you. I promised Grandpa.
Okay. That's your charm.
I'll try to hold back even if I want to know.
It's nice seeing you. I didn't think I'd get to.
Go home first. I'll be right there.
Can't you go with me?
Let's go together now.
I'd like to as well,
but that jerk needs to adjust quickly for your sake.
Don't worry.
I can handle anything that jerk dishes out.
Do you want to go on a date tomorrow?
Like average people.
Sounds good. A date.
Like average people.
I checked, but nobody here uses that number.
Then can I get the numbers of your former employees?
The person in charge left for the day.
I understand.
If you find out, please give me a call.
PK again?
Someone from there came by before.
Was it...
- this person? - That's right.
That young punk was such a jerk.
You scared me!
You're telling the truth this time.
- What are you doing? - Hold on.
Don't lose it again.
Your mom will be sad.
You're really the best slave ever.
You're the best master ever.
Thanks to you, we got this far without getting caught.
Given that silly grin, you must be thinking about him.
Why don't you get confused?
Everyone else gets confused, but not you.
You recognize him right away even when we're together.
I can tell just by looking.
The power of love.
Do you like him that much?
Why do you hate him so much?
He doesn't hate you.
He acknowledges your existence...
and thinks of you before himself.
But you keep harassing him.
You even did that to his face.
Would you like it?
If something that looks exactly like you showed up,
wore your clothes, acted like you, and took your dad.
And people say she's better than you.
How would you feel?
I'm throwing out all the clothes that he wore.
I'm childish, aren't I?
- What are you doing? - I'll do it.
You should rest. I'll tell them...
to bring in new clothes and watches tomorrow.
I suddenly feel like crud.
Why? Do you pity me?
I only thought about doing the best I can for you.
I didn't have time to think...
about how you'd feel once you woke up.
Everything you're feeling toward that robot...
is all because of me.
I'm sorry.
What's this? Why is this empty?
That's where the batteries were.
Doesn't he have a weakness?
What exactly is that manual mode?
How can I control him?
What's wrong with you?
Did something happen?
Just.
I'm just curious.
Sin.
People think you're thoughtless,
but I know.
You're not thoughtless.
You think way too much.
Please don't try to bear it all alone.
I know I'm lacking, but you still have me.
You must be tired. Get some rest.
I'll tell them to take these away.
Yes, sir.
I'll tell Sin.
Apparently, Dr. Oh is very ill.
You should go to her after work.
Thank you again.
- You can wait outside. - Pardon?
A mere bodyguard doesn't belong here.
Are you that clueless?
Yes, Mr. Nam.
I will wait outside.
What? Can't we work without So Bong?
No, sir.
What happened with the safety test?
(Safety Test Results)
The self-driving aspect and...
the communication protection aspect passed easily.
The core feature is automatically switching...
to auto-drive when the driver's health fails.
Luckily, those safety features passed as well,
so we should get an official test drive permit soon.
As expected,
you're the best, my son.
I told that punk to visit his sick mom,
but he didn't show up.
Sin.
Wake up, Dr. Oh.
Which Sin are you asking for?
The Sin who cares for you is here.
Let's talk, David.
Don't make that face.
It's human beings' contemptible look.
Who told you that?
The chairman?
Yes.
He said he has known that I was a robot.
- My son. - What's your relationship with him?
Why did you deceive Mom?
We needed money to make you.
We couldn't give up.
You know scientists can't continue without funding.
I'll explain everything to her later.
Please give me a chance.
I thought Mom would be okay without me...
because she had you.
But you lied to Mom and me for money.
Don't say you gave birth to me with your heart anymore.
I don't need a dad who lies to his family.
Grandpa...
Hey!
Who are you? We've never met before.
Fine. Forget it.
I'll go have fun by myself.
Just kidding. Let's go.
(Fortune Teller)
You don't have a living person's fortune.
You're full of metallic energy.
Are you a hunk of metal?
She's good.
She's really good.
How could she see that right away?
Can you play the piano?
No.
That's so cool.
(Video of pianists)
Protecting Kang So Bong...
is top priority from now on.
My first friend, Kang So Bong.
Thanks for being my friend.
I want to watch a movie.
Okay.
Here's your popcorn.
Thank you.
Can you taste it?
How does it taste?
Sweet?
Because you're with me?
What?
(Moonlight Blade)
This is just an ad.
Why are you staring so hard?
It's my first time in a theater.
It's all so new to me.
This movie is supposed to be super sad.
It's starting.
It's because the movie is sad.
I know...
I don't need to hug you.
The tears are sparkling...
as they fall.
I'll get you some napkins.
Where are the napkins?
That way.
Thank you.
Thanks.
I heard.
I had so much to say.
But now that I see you,
I can't think of them.
It's so darn sad.
You said...
you'd never confuse us.
(Are You Human?)
M City.
Only you can make my dream a reality.
I'll show Grandpa...
what's real and what's fake.
Don't hurt people. If you do,
I'm gone.
Imitate him all you want. You can never be like him.
- How dare you... - What are you doing?
Switch to manual mode.
