Joon-suh, that's your baby sister Isn't she pretty?
I'll be right back Don't go anywhere
You can't play in here
Did you drop these?
Yoon Joon-suh, that big jerk...
Yoon Joon-suh... What are you doing here?
Did you throw this letter away?
I'm sorry. I didn't mean to throw it away,
but the sender's name wasn't on it. I couldn't return it to you.
Don't you like me?
There is someone else.
What are you doing here?
Here.
Don't you do this too.
- What happened? - Tell us.
What's this? Is this ours?
What happened? Tell us what happened.
He didn't even open it. That jerk.
How could he do this?
Wait for me.
Joon-suh, I can't ride a bike well.
I did something my brother hates again.
I do regret it.
But it's not entirely my fault.
I can't disobey my seniors. And if he doesn't want to be the target of their affection,
he should get himself a girlfriend.
I'm tired of being the messenger.
No, I'm not.
I just hope you'll give me a break.
You're forgiven.
You should've done that earlier.
By the way, who is she?
Who?
You said there is someone.
Be quiet.
Who is she?
It's a secret.
Don't say anything to Mom and Dad.
That's my prerogative.
Yoon Eun-suh.
It's my prerogative.
Fine, let's play paper, rock, scissors for it.
Fine.
I'm ready.
I lost again.
Why do I always lose?
You always choose rock.
It's raining.
Why doesn't it stop?
It's only a passing shower.
I'm all wet. My skirt is getting heavy.
What are you doing?
It's all right.
There is no one around and I'm wearing a slip.
A slip?
When did you start wearing those?
I'm all grown up now.
What are you looking at?
Your brother has a crush on someone?
He said it's secret.
Isn't there anyone for you?
There is.
Who is he? Is it someone I know?
It's Joon-suh.
Let me see.
When did you get so big?
I don't know.
Maybe I take after you. You brat.
It's your turn.
When you go to college and get a boyfriend, tell me first.
I will.
Mom, you'll be rich.
Why? You have fat earlobes.
Grandmother was the same way.
Really? But mine are thin.
Really?
They used to be fat. When did they get so thin?
I guess I'm not your daughter. I don't look anything like you.
I must be adopted.
What?
My pretty Eun-suh.
I'm full.
I ate too much.
Eat more. So your chest will get bigger.
Mom!
Honey, Eun-suh has already...
Already...
- Already? - Mom.
- Her chest. - Chest?
Let me see.
Mom, stop Joon-suh.
If I'm elected the class president again, I can't promise I'll abolish homework.
But I will work hard for everyone.
How does that sound?
You're thinking I'd say that it sounds pretty good, right?
And you thought, "she'll never be elected," right?
You're thinking "I'll win the election and show him," right?
You were thinking "I hope she loses to Choi Shin-ae," right?
Choi Shin-ae?
She's my rival.
Is she giving you a hard time?
No.
Senior.
- Freshman, are you here to see me? - Yes.
What is it?
I have a favor to ask you.
I really like your painting displayed in the hallway.
So?
I want you to paint a picture for a poem I'm submitting to the poetry contest.
You've never met me before, have you?
No.
Then why should I paint for you?
I'm rather busy. Sorry.
Shin-ae. Choi Shin-ae.
Wait.
Is her name Choi Shin-ae?
Yes.
Then she's in Class Two?
Yoon Eun-suh.
Choi Shin-ae.
Yoon Eun-suh.
Choi Shin-ae.
And this is the last vote.
Yoon Eun-suh.
Yoon Eun-suh has twenty-nine votes and Choi Shin-ae has sixteen votes.
So the class president for the second semester
is Yoon Eun-suh and Shin-ae is the vice-president.
And our class took first place for the first midterm.
And Choi Shin-ae is number one in the class.
Congratulations.
Everyone must know about the illustrated poem exhibition next month.
Yes.
The literature teacher recommended Yoon Eun-suh and Choi Shin-ae.
My opinion is Eun-suh should do it.
Shin-ae participated in the exhibition in the first semester.
And Eun-suh's brother can help her with the illustration.
Shin-ae, you don't mind, do you?
No.
And Eun-suh's mother will send us rice cakes to celebrate our good work this Saturday.
That's so cute.
Really?
I envy you.
Everyone, Eun-suh's mother will bring us rice cakes this Saturday.
Shin-ae is at the top of the class, but why is Eun-suh the class president?
Eun-suh won the election fair and square.
Yi Kang-hee, you stay out of it.
- Are you her maid or something? - What?
Thanks to your brother who is like a prince, you're participating in the poem exhibition.
How lucky.
Yes, I'm lucky.
If my brother is a prince, that makes me a princess.
Thanks for calling me a princess.
Yes, Joon-suh is a prince.
And I'm his princess.
Let's work together.
And if you've something to say, you say it to me. You can talk to me anytime.
Eun-suh, something terrible happened.
Your slip is hanging on a tree.
I'm sure Shin-ae did this. I'll go tell the teacher.
Eun-suh.
Isn't that Eun-suh?
Are you mad? Are you mad at me?
I'm mad, too. You teach her a lesson.
Who did this?
- I don't know. - Her name is Choi Shin-ae
and she's giving Eun-suh a hard time.
Choi Shin-ae?
- No, it's not her. - Of course it's her.
It is her.
I'm sure it's her. He doesn't know who she is.
I think he does.
Joon-suh.
Eun-suh.
Eun-suh!
What happened? Is she badly hurt?
Where is she?
It was my fault.
If I had waited for her...
I left her behind... It's my fault.
She's badly hurt.
She has to get an operation.
How long will the surgery take?
You don't have much to worry about.
She'll have a scar, but other than that, she'll be fine.
She'll need a blood transfusion.
- I'll give her my blood. - I will.
Who has type B?
Pardon?
Your daughter's blood type is B.
That's impossible.
She must be type O. We're both type O.
You're not mistaken?
If not, she can't be type B.
Let's run a blood test.
Why should we take a blood test?
We got the test results back.
You and your wife are both type O.
If we're both type O, our daughter can't be type B...
That's right.
There can't be an exception?
No, it's impossible.
What happened? Did something happen to Eun-suh?
No, don't worry about anything.
Honey.
Let's talk.
I shouldn't have come home.
I should be there when Eun-suh comes to.
I should go back.
You can bring her a change of clothes.
Let's talk.
Talk about what? There is nothing to talk about.
Her blood type...
We're both type O.
What about it?
Didn't you know your blood type?
- Honey, Eun-suh's blood type is B. - What does it matter?
She may not be our daughter.
No!
Eun-suh, seeing you like this,
I'm scared you'll never wake up.
Did it hurt a lot?
I'm sorry I hurt you.
I'm really sorry.
You're forgiven.
Yoon Eun-suh.
You were going to apologize when I was unconscious
and not say a word when I woke up, right?
How did you know?
Mom and Dad must be shocked.
They are. They went to get you a change of clothes.
They'll be here tomorrow morning.
What about you?
I can't leave you here alone.
I meant, were you shocked too?
No.
You're too mean.
My heart almost stopped.
You're forgiven.
- Why... - Ouch.
- Does it hurt? - I'm telling Mom on you.
I'm never playing with you again.
I've been thinking.
If they were switched at the hospital...
Eun-suh is my daughter.
There must be a mistake. Eun-suh is my daughter.
What if she isn't?
If our daughter by blood is out there...
- Honey. - I don't know what's going on.
I don't want to hear anything. I won't hear it.
There were two babies born that day.
The mothers' names are Yi Kyung-ha and Kim Soon-im.
Ms. Yi Kyung-ha's baby's blood type was type O.
And Ms. Kim Soon-im's baby's blood type was B.
It was type O?
Yes, that's what the records show.
If your daughter's blood type is B,
they must've been switched after their first sample was taken...
Please, let go of me.
Calm down.
Can't I do the illustration for your poem?
Why?
Let me do it for you. You like my work.
Did Eun-suh ask you to do it?
Stop harassing Eun-suh from now on.
What do you mean? Do you think I'm a thug?
If you're not, don't harass my sister.
If you do, I won't forgive you.
So I'll do the illustration for you if you promise not to harass her.
Who cares about a stupid illustration?
Shouldn't you be asking me nicely instead of threatening me?
I might consider it if you get down on your knees.
Satisfied?
Don't bother Eun-suh anymore.
You creep... What's the big deal about patting your behind?
I'll never eat here again.
Good riddance.
This behind is not for your ogling.
You creep!
What would you like? We only have stew.
What brings you here?
It doesn't look like you'd eat at a place like this.
We came to discuss your daughter.
My daughter?
Are you her teacher? Is she in trouble?
No.
Is her birthday October the fourth?
How do you know that?
You gave birth at Karam Hospital.
Who are you people?
May we see your daughter?
What's going on?
I don't want to see her. I'll never see her.
You lied to me. You didn't say we'd meet her.
Honey, be reasonable.
What's going on?
- I'm going back to Eun-suh. - What's the matter with you?
No, what's the matter with you?
Didn't you hear me? What's going on?
Why are you doing this at my place?
Stay out of it, you don't know anything.
What?
Our daughters have been switched.
Our daughter and your daughter were switched at birth.
We confirmed it at the hospital.
Let's go to the hospital.
Let's go home first and...
Take me to the hospital. Take me to Eun-suh.
How could you be so cruel?
How could you do this to Eun-suh and me?
Don't get out. I'll go alone.
- Mom. - Eun-suh.
Why did you come? You didn't have to.
It's raining. You're scared of rain.
I have to protect you.
I'm not a baby anymore.
You're not my baby anymore?
I'll protect you.
I'll make sure no one hurts you.
Mom.
Eun-suh, my Eun-suh, my daughter...
I'm going to protect you and see you go to high school.
I'm going to see you meet a nice young man
and pick out your wedding dress when you get married.
I'll hold your hand before you walk down the aisle.
And when you have a baby, I will...
Mom.
Eun-suh, shall we order Chinese noodles?
Really? Yes.
Isn't she pretty?
Don't go anywhere. I'll be right back.
Did I wake you?
- Is Eun-suh all right? - Of course.
- Where is Joon-suh? - I'm going to take a picture of him.
You can't play in here. Did you drop these?
Joon-suh, what were you doing in there?
Let's go.
That jerk died.
You poor thing... Never got to see your father.
Then again, you're better off without a father like him.
Our daughters have been switched.
Their place was a mess.
That woman was a mess, too.
Everything is a mess.
I'm sorry.
I...
I love you and Eun-suh more than my life.
I know.
But when I think about the baby who's been living in that place...
Honey, let's go on the professor exchange program.
Before it's too late, before anything happens...
Let's go to America and put everything behind us.
I'm done.
Brother.
That's strange. You and Mom both.
- Would you like some juice? - It's all right.
What's the matter? Is something wrong?
I'll tell you a secret.
Secret?
- I'll tell you whom I like. - Really?
Who is she?
She's a bit clumsy and stubborn too.
And she's a sloppy eater.
She must be pretty.
No, her hair is about this long and she has round eyes like yours.
And she's about your height too.
But she's really ugly.
And she's really stupid.
I've been giving her a hard time for a long time,
but she keeps following me around.
I'm really sick of her.
She can't even ride her bike well.
That's me.
Are you teasing me?
I'm not teasing you.
Eun-suh, if we weren't siblings, do you think we would still have met?
Of course. We were destined to meet.
Fine, let's play rock, paper, and scissors for it.
If you win, it's destiny, and if I win, it's not.
Fine.
Wait.
That's strange. Why do I always lose?
You always choose rock.
I'm ready.
I won.
See, I'm right. We were destined to meet.
Good work, rock.
Tell the teachers we'll be moving to the States next month.
All right.
I want to leave as soon as possible.
Can you do it?
Don't you want to meet her once?
No.
Are you...
No, I won't see her.
I don't think I can turn away if I see her.
I can't turn my back on Eun-suh. I won't see her.
Joon-suh painted this illustration for the student
who replaced Eun-suh in the exhibition.
I'm very grateful.
- He did what was right. - Thank you.
- Will you excuse me for a minute? - Certainly.
This poem is beautiful.
Choi Shin-ae... Who is she?
You don't have to know.
I told you about her. She's the head of the class.
Where is she?
Is this where the poem exhibition is taking place? / Yes.
- Mom! - Shin-ae.
Are you crazy? What are you doing here?
I came to look at your poem.
- Go home. What if someone sees you? - It's all right.
Where is your work?
