Have some more water. I'll go get my phone.
Hey, hurry.
Come over here.
It must be our housekeeper.
We're good.
Junwoo.
Mom.
Come over here.
So...
...you two are...
So that's why you asked me about my first love last time.
Are you two...
...dating?
Yes, that.
Hello.
I'm Yoo Subin.
Yes, hi.
Of course, I know you.
You're Subin.
I was planning to tell you...
...but it hasn't been that long...
...since we started dating.
Right. And in the meantime, things happened.
Congratulations, you two!
Congratulations, Junwoo.
You two are really dating?
Is that right?
Congratulations. I'm so happy for you.
Let me have a good look at you, Subin.
You're my son's first love.
Thank you for being Junwoo's first love.
My gosh, why am I getting all teary?
I can't believe such an amazing girl like you, is my son's girlfriend.
This makes me so happy.
Thank you.
By the way, Mom.
What happened?
Huh?
Why do they look exactly the same?
Let me see.
At first, I wasn't going to accept the job.
Subin's mom was also against it.
But if you think about it,
it's just work.
It's just a job, you know.
While the restaurant is being renovated, I thought I might as well do something.
But I should have thought about my son's position.
I was too rash,wasn't I?
On top of that, Subin is now your girlfriend...
What should we do, Junwoo? You're uncomfortable with it, right?
I'm fine with it.
I'm just worried that you might have been having a hard time.
No, not at all.
You know I like to drive, cook, and clean.
It fits me perfectly.
Oh no. I should go.
I have to go pick up Subin's mom.
She doesn't know that you two are dating yet, right?
Yes.
Just tell her.
I want you to be able to date freely.
I feel bad that I'm the only one who knows.
We'll tell her.
But...
...not for now.
That's right.
You'll need some time to mentally prepare yourself.
But don't take too long, okay?
Okay.
Bye.
Have a great time at work today.
Drive safely, Mom.
-I will. -Good.
Bye.
Junwoo, congratulations!
My son's first love!
My gosh! My son is in love.
♪ I'm in love...
Bye.
Mom.
You couldn't come with me because my mom showed up.
My mom just left.
Are your hiccups completely gone?
Yes. They're gone.
I can see that.
Subin.
I felt anxious, so I was on my way to see you at work...
...but I bump into you here.
I'm sorry.
I really had no idea.
Why are you sorry?
My mom...
...was just working.
Are you uncomfortable with it?
I'm really okay with it.
No.
If you're okay with it, then I'm okay.
I'm glad that my mom took a liking to you.
Though, I already expected that.
By the way,
your mom is really nice.
She's so young at heart.
Right?
My mom thinks we should tell your mom about us.
She feels bad that she's the only one who knows.
I see...
Let's go.
Thanks for walking me.
Take care.
I will...
...while thinking about you.
Bye.
Okay.
Bye.
All right.
Bye.
-Get home safely. -I will.
Why are you so late?
Where have you been?
I was at the library because of the performance assessment.
You should've given me a call. Then, I would've sent the driver over.
Are you tired?
-Hi. -Hey.
You need to see this.
Someone posted something strange.
(Ma Hwiyoung from Class 3 is suspected of having manipulated his grades.)
What nonsense is this?
Ma Hwiyoung? Is this for real?
No way. Why would he? He's already top of the class.
Maybe that's why he's always been in first place?
Do you think it's true?
I don't think it's a rumor. It seems like a fact.
Oh my god!
Romi.
Kitae, is this true?
We don't know anything for sure yet.
Let's just study.
I'm just curious.
-Yes, ma'am. -Right.
We're looking into it at the moment.
-We're not sure... -Please don't worry.
-Tell her we're looking into it. -We're looking into it now, ma'am.
Don't be too concerned.
Hello, ma'am. Right.
-I see. -We're looking into it now.
-My gosh. -That's right.
Mr. Oh, have you seen this?
Yes, just now. I was in the classroom.
Ms. Bae, what are you waiting for?
Delete the post immediately.
Hold on. I think we shouldn't just delete the post.
As the administrator, we have the rights to remove any false information.
Yes, I'm aware. But I think it's only going to raise the suspicion.
We should first release an official statement to explain the situation.
And then decide if we should delete...
The kids sure are fast.
They already have uploaded it everywhere.
This is crazy.
All my friends know about it too.
It'll die down soon. We had something like this last year.
My grandma said if you hear a rumor, it's most likely true.
What did Hwiyoung say?
I forgot. You guys aren't on good terms now.
What did Kitae say?
I forgot. You too.
What did Ohje say?
I forgot. You too.
What is the matter with all of you?
Kwon Daheen, go home.
Because of you, the mood here is so somber.
My house is swamped right now.
My relatives came.
I want to stay here.
Is my house is some kind of a care home?
(Hwiyoung)
Stop looking at it.
There's no point.
Did something happen?
Something I don't know about.
No.
Nothing happened.
So don't worry yourself about it.
Just study.
You shouldn't worry yourself about it either.
And stop drinking.
I didn't drink.
I had juice.
Study.
Yeonwoo, did you wait long?
Did you bring what I asked you?
Yes.
You saw the post, right?
The mothers are causing a ruckus.
Leave them be.
When Hwiyoung gets first place again,
they'll compliment him like it never happened.
You took off your cast.
I did. That's why I came late.
Well, I guess you won't need me anymore.
Why? We still have some time left on our agreement.
Still, your hands have recovered now.
It's still quite uncomfortable. Why don't you help me a little longer?
So... I think my son has a girlfriend...
-Oh, my gosh! -Is it a rat? Where?
It's not a rat.
How can your son be dating so soon?
He'll be a senior next year. This is a big problem.
I feel so bad for you. Goodness.
I know, it is a big problem.
Did you just finish work?
Yes.
Are you from the cram school?
Yes.
You must be tired.
I'll see you tomorrow.
Okay.
By the way...
You're pretending not to know.
You probably already saw the post.
Do I need to bring it up?
To be honest...
...I can't be nice to you.
See you.
Even though that brat acts all tough,
but he's actually more vulnerable than anyone.
You're a true teacher.
You were so furious because of Hwiyoung's mom,
but you're still worried about him.
Do you realize that that's all you've been talking about this whole time?
Have I?
I'm sorry. You must have been bored.
A little bit.
A little bit?
My mom...
...also forced me to get first place all the time.
Why can't you get a perfect score?
Raise your head.
Raise your head!
You must get a perfect score and be first place.
Didn't I tell you that's the only way for you to survive?
Oh Hankyeol!
To me, she was such a scary and hysterical mother.
But for some reason, she seemed unhappy.
So I tried my best to cheer her up.
But in the end, it didn't turn out that well.
Later on, even going to school was difficult...
...so I dropped out in eighth grade.
Eventually, I didn't make it into the university my mom wanted.
Growing up, I used to resent my mom a lot.
My mom got ill and passed away when I was in university.
After that...
...I was filled with remorse...
...and felt sorry for my mom...
...who devoted her everything to me.
I was also sorry for the Hankyeol back then.
I'm sorry.
I suddenly ruined the mood.
Mr. Oh.
I'm sure your mother will really be happy,
to see you become such an amazing teacher.
Do you think so?
Of course.
"Oh, my. My Hankyeol, I'm so proud of you."
She'll probably say that.
I really...
...hope that's true.
It's probably Hwiyoung's previous homeroom teacher.
We've done so much for him. What more does he want?
Maybe the person who posted that is Mr. Oh Hankyeol.
We should change his homeroom teacher.
How can we do that again?
How can you think of that after all the mess that happened.
What are you talking about?
How have you been behaving at school for something like that to be posted?
Did something happen between you and the previous homeroom teacher?
Then the reason why he was injured...
Don't be silly.
And what is this about Mr. Oh?
-What did you two do? -"What did we do?"
It's all for you, don't you know that?
If only you do well on your own,
I wouldn't have to ask other people for favors!
Honey! Don't.
Honey...
Hwiyoung, let's go upstairs.
Come on.
There's someone else I'm suspicious of.
Who?
The one you really like...
...the beast.
Ma Hwiyoung is probably having a mental breakdown right now.
My mom thinks we should tell your mom about us.
She feels bad that she's the only one who knows.
You know that boy?
No.
You know the son of my temporary driver?
Apparently he has a girlfriend.
Can you believe that?
He's so immature.
His mom is working so hard right now.
I guess he's given up on going to university.
Yoo Subin.
You better study really hard this time.
You have to do well on the final exams.
Remember Hwiyoung's mom...
...took you out of the tutoring class because of your grades.
You shouldn't forget that humiliation,
Okay?
Why?
Do you have something to say?
Something to say?
I'm...
I'm just thirsty.
Go get some water.
If the post about that rat's son is true, it'll be perfect.
I hope it'll crush her.
That sneaky rat.
Subin.
Let's go.
Okay.
Hi, Hwiyoung.
That's the sign of exam coming up.
That's right. The final exams.
"Oh, no, the final exams!"
You're suspicious of me, aren't you?
It wasn't me.
Why would I post something like that?
My dad got a promotion,
I didn't have to transfer,
and I even joined an exclusive tutoring class,
that I've never begin to imagine to be a part of.
Why would I do that to a friend that I'm grateful to?
Jo Sanghoon.
What do you want, Lee Kitae?
Weren't you fired from being Hwiyoung's butler?
Lee Kitae.
Just go on your way.
Wow.
What is this? Is this some sort of broken friendship?
This is an interesting turn of events.
Hwiyoung, I'll be your best friend from now on then.
Why? I'll be nice.
I'll be a good friend, Hwiyoung.
Don't worry.
I ran into Hwiyoung last night on the way home from work.
He said he's not bothered by that.
Let's go.
Are you following what Choi Junwoo did?
This worked for Choi Junwoo.
This is...
Have you given up on Romi?
Is that a fish?
You punk.
I'm serious right now.
You think she'll be jumping with happiness if you give her this?
This drawing is too simple to show that you're serious.
Yoo Pilsang...
...let me see.
Come on.
(Hwang Romi)
You need to draw the outline first.
Like this.
Now, you have the outline.
Then...
Wow. Goodness.
Choi Junwoo. You're good at drawing.
Now, you need to highlight her features.
What's Romi's features like?
Her face is small and she has pretty eyes.
-Like this? -Wow.
Choi Junwoo...
What else?
She has cute eyebags.
-Cute eyebags? -Yes.
Her bangs are similar to mine.
Okay, got it.
Daheen, let's go and eat.
You'll really faint at this rate.
Kwon Daheen...
...are you going to be this pathetic just because of one boy?
You should get back at him by dating a better one.
Yes, I am pathetic!
Do you know what love is?
All you know is how to lie. Do you know what true love is?
-Why are you fighting? I'm hungry. -Who do you think you are?
-Stop it. -Who do you think you are?
Hey, Jung Ohje.
What's your problem?
Romi.
How are you to make Kwon Daheen starve herself?
Who are you to be so cruel to her?!
Hey, Hwang Romi. Why did you hit Ohje?
Talk it out with me. Don't hit Ohje.
Jung Ohje, you saw that, right?
You need to take responsibility.
Give back all the love you've received from her.
Just because it's one sided, it doesn't mean you get to be irresponsible.
That's basically bad manners.
Daheen.
Kwon Daheen clearly still has energy left in her.
She's not dying.
Mr. Oh.
I'd like you to be honest with me.
About what?
About my parents' faults.
Huh?
I'm sorry about the petition for a new homeroom teacher.
It's fine.
The parents did that because they want you guys to get better grades. That's all.
But they withdrew it right away.
You must be bothered by the post. Right?
Are you also doubting of me?
No.
I trust you.
Hwiyoung...
Theoretically speaking...
...even if something unexpected happens...
...I'm sure...
...it's not your fault.
I never cheated in anything.
I know.
I know that.
Hwiyoung, have you eaten?
Do you want to go eat something?
No. I should leave.
Mr. Oh has a meeting, so I'll update you all on a few things.
There isn't anything special.
I've posted all the updates regarding the performance assessment.
Hwiyoung.
The rumors about your grades aren't true, right?
Did another one come up?
What do you guys think?
I'm just curious.
Let's get ready for class.
With the way things are going, it's important for us to suppress the rumor.
I really hope it doesn't get worse.
Shouldn't we release an official statement?
No. Why should we when it's not true at all?
Mr. Oh, please do your best to make sure...
...your homeroom students aren't distracted by the rumors.
The same goes for the rest of you.
Make sure your homeroom students keep quiet.
Please give them a stern warning regarding this.
-Okay? -Yes.
Daheen's recovering from a breakup project.
It begins now!
Hello, everyone. My name is Kwon Daheen.
I just broke up with my boyfriend a few days ago.
How's Daheen?
Is she doing fine?
All my friends are worried about her.
It's been hard.
Let's cheer up.
Take this.
It's red ginseng.
I usually drink this when I study.
I brought one for you.
Thanks.
(Final Exams Study Plan)
This is so packed.
But I must follow this plan.
Even though we're dating, I need to have my grades up,
so that I can brag it to my mom.
I'm going to do really well on this exam.
Don't stress yourself out.
If you set your expectations too high...
...you might get disappointed.
Don't say that.
I have to do well.
We promised your mom...
...that we'll be honest with my mom.
Yes, let's do that.
What is this?
We can't even tell people that we're dating.
We have to hide from everyone.
It's not like this is the Joseon era or something.
It's because we're 18.
What's wrong with being 18?
Is it a sin to be 18?
Is it a crime to like each other?
It might be.
Why?
Because we discovered the best thing...
...at the best time of our lives.
I guess you could call it a sin.
You actually came from the future, didn't you?
Right now...
...you're about a million and twenty-nine years old.
But you realized that this is the best time of your life so you came here, right?
Gosh, I'm in trouble.
Why?
What's wrong?
How did you know?
About my true identity.
Sit down.
Sit.
What should I do with you?
Should we just...
...pluck up our courage?
Let's tell her that we're dating.
Let's stop running away and lying to her.
"We're dating."
"We're dating." Like that.
No, I don't want you be reckless.
And I don't want you to be intimidated.
You're always hiding behind the trees in my neighborhood.
I'm not intimidated.
Hiding is fun.
Still...
I'm sorry.
I feel bad.
I'm happy...
...but it feels weird.
How so?
It makes me sigh.
Same here.
My gosh!
It's my dad.
This is great. You should say hi to my dad.
Right now?
Yes, my dad is different from my mom. He'll be more understanding.
Wait.
Wait, it got disconnected.
I'll call him back.
Hi, Subin. I'm...
Didn't I told you not to call Subin without my permission?
Geez, you control freak.
I don't have time.
What is it you want to talk about? Hurry up.
There you go.
The divorce papers.
I'm not signing that.
Are we done?
Yoon Songhee.
Let go.
We don't love each other.
What did you say?
We don't love each other.
For goodness' sake.
Are you 18?
Why are we sitting here talking about love?
What should we do then? Keep living like this?
Keep living uncomfortably like this?
I'm not. You're the only one who's uncomfortable.
Don't you think you brought that upon yourself?
Songhee.
If we keep this up...
...it will only consume you.
It'll be great if it consumes you too.
Mr. Yoo Jongsu.
Good luck living uncomfortably in the shadows.
And if you file a divorce lawsuit,
you know that it'll only disadvantage you, right?
Since you're the one to blame.
You should have some dignity...
...as Subin's dad.
Bye.
That was quick.
Yes.
They came together.
Do you want me to run them over?
What are you doing?
No. Stop the car!
Are you insane?
Wow, my daughter.
Looks like you're studying hard.
I made a promise with you.
Cookies?
Yes.
My driver told me to give these to you.
Now that your arm is healed,
do you still need a driver?
I wanted to pretend it still hurt to make her stay,
but she quit.
She going back to her job.
You must've grown really close with your driver.
Yes.
I'm comfortable around her.
We've decided to be friends.
Really?
Yes.
Get back to studying.
Okay.
I think our moms have gotten closer.
This is good news for us, right?
You're right.
Mr. Choi Junwoo, all you have to do now is do well on the final exams.
Let's study hard!
Okay.
Don't worry.
(Final Exams Study Plan)
Good.
This is good.
The number you are calling is...
This is weird. Where's Jimin?
I can't reach her all day.
Does she have another test today?
Hwiyoung...
...how are things going?
If you want to discuss anything,
you can call me anytime.
Okay?
Thank you.
Gosh, this emotionless brat.
He should at least use an emoji.
Shinyoung.
What do I do?
I'm afraid.
Yes.
I'm on my way back from work.
What about you, Mom?
Did you arrive safely?
You must have a lot of work to do.
Don't worry, I'll be fine.
Mom.
Are you crying again?
You're not, right?
Don't worry.
I'll be fine on my own.
Okay.
Do you still sleep with the lights on?
Well...
You should practice sleeping with the lights off.
You can fix it.
Then...
...imagine that I'm with you.
With me?
Yes.
Imagine that I'm with you to protect you.
Have you turn the lights off?
Yes.
Do you feel sleepy?
Not that much.
Even when I'm protecting you?
That's what's making it harder.
Why?
Because imagining you here with me...
...makes my heart flutters.
Don't worry. I'll help you fall sleep.
All right.
Close your eyes.
You're feeling sleepy.
It's okay.
You're relaxed.
You're doing great.
That's correct.
My gosh, I'm so proud of you.
I'm touched. Well done.
Sorry.
I got too excited because you solved it.
Why does this...
...remind me of the story about Princess Pyeonggang and the fool, Ondal?
Nonsense.
I'm just so proud that we're studying together and you solved the question.
So you're proud of me because I'm stupid like him?
You know what?
That should be your nickname.
Jundal.
Jundal, instead of Ondal.
I'm Pea,
and you're Jundal.
Jundal. Jundal.
Isn't that cute?
Jundal.
Hey, Jundal.
Jundal.
I love you.
Okay.
That's not fair.
He suddenly called me while I was cleaning.
Then you should've told me earlier.
So that I could prepare myself mentally.
I was worried you'd be too distracted to study because you're preparing yourself.
We were able to study for two hours thanks to that.
You really are like Princess Pyeonggang.
I'll go ahead and meet my dad. I'll text you later.
You can come in then. Okay?
Yes.
Let's go.
Hello, I'm Choi Junwoo.
Subin, how have you been doing?
Good.
Studying must have been hard on you.
Of course. It's harder because of mom.
Oh, dear.
Subin.
Today...
...I have something to tell you.
What is it?
I...
...will be divorcing your mom.
Dad.
I thought it's best to be honest with you.
I'm sure you could already tell...
...that we're not on good terms with each other.
Gosh.
I'm too ashamed to face you.
But you see...
...I don't want to pretend that we get along...
...or put an act in front of everyone anymore.
That's why I've decided to divorce your mom.
But she's against it because she's worried that it'll shock you.
Subin.
From what I can tell...
...you're not a child anymore.
You're 18.
I think you're old enough to understand.
You'll be an adult soon enough.
Right, Subin?
What?
Am I right?
You understand it, right?
It must be...
...so easy for you adults.
What?
Sometimes...
...you tell us...
...that we know nothing because we're too young.
And tell us to just study.
But at other times, you tell us...
...that we've all grown up now.
That we're old enough to understand everything.
You change your words...
...whenever you want.
No. Subin, listen to me.
It's just that ever since you were little, you've always been so mature...
...and more thoughtful compared to kids your age.
No, Dad.
I just...
...pretended to be mature, that's all.
I have to do that...
...to not burden the both of you.
That way, you'd feel less guilty for me.
But you know what?
To tell you the truth...
...that was not what I wanted.
You're back.
Let's go.
My dad said he's a little bit busy today.
You can meet him another time.
Okay. Did you have a good talk?
Yes.
You have work today, right?
Yes...
..but should I skip it today and go have fun with you?
No. You shouldn't.
You have to go to work.
Just for today.
Let's just have fun today.
Junwoo.
Yes?
What is the one thing you regret the most in your life?
I'm not sure.
There's too many.
Pick one.
The one thing that have been bothering you the most.
Not being able to tell him that it was me.
A while ago...
...when I was thinking of transferring again...
...I went to find my dad at his house.
I already knew where his house is...
...but couldn't make myself go there.
But rather than running away...
...I thought I might as well give it a go.
But my dad...
Don't you...
...recognize me?
What?
He didn't recognize me.
That's what I regret the most.
Going to see him?
Not being able to say...
...that I was Choi Junwoo...
...at that moment.
It felt like I was being erased...
...at that moment.
I've been regretting it.
But it felt awkward to go back and tell him.
Let's go back...
...and tell him.
So you won't regret it anymore.
Okay?
Would you like that?
If it's something you regret.
Okay.
Can you take a look at this first?
You even drew something?
Yes, just a little one.
Good job.
Let's go.
I hope all your regrets are gone now.
Are you feeling better?
What?
Since I got to get rid of my regret.
You have something you regret about, so you trying to relieve that...
...through me.
You knew?
You must have been upset...
...after seeing your dad, right?
Did you do that to make me feel better?
I was planning to do it someday anyway.
So it's fine.
Plus, I wanted to make you feel better as well.
Aren't you hungry?
It's been hard for me nowadays because you're not around anymore, Yeonwoo.
I mean it.
You must miss your son.
I have no choice.
We've always lived like this.
I miss Junwoo, and you too, Songhee.
Come visit me then. I'll treat you to something delicious.
Okay. Get back to work.
It's a railroad.
Isn't it beautiful?
It feels like a different world.
It is a different world.
It's the world I live in.
I've been here before.
What?
That time...
...when I didn't trust you.
I wanted to come up here.
It's nice.
Is that your room?
Yes.
I want to see it.
No, wait.
You can see my room next time.
It's in a mess.
Sit down here.
Thanks.
-I'll enjoy this food. -I'll enjoy this food.
The thing I regret most right now...
...is when...
...my mom and dad said they wanted to get a divorce...
...but I stopped them.
Mom, wait!
Mom, don't go.
Don't go. Don't go, Mom.
Mom.
You said you'd understand even if we got divorced.
No. I can't understand. I don't want you to split up.
Don't go, Mom.
Even if we get divorced,
your dad and I will still be friends,
and you'll still be our daughter, whom we love the most in this world.
No. I don't want you to go. Please.
Mom, I'll do better.
I'll study harder and become a better daughter.
I promised Dad too. He promised to change.
Mom, don't go.
Mom, please don't go.
Please stay.
Don't get a divorce.
Don't cry.
I'm sorry. I'm sorry.
I won't get a divorce.
I'm sorry.
Back then...
...I thought I was doing the right thing.
I didn't know they were just living together for my sake.
They pretended to get along.
They put an act as if they're happy.
I found out later.
That I was wrong.
But what can I do now?
I can't turn things back.
It's all my fault.
It's not your fault.
You didn't know back then.
You thought that was the best solution.
Why didn't I know that back then?
I feel bad for mom...
...and Dad is not doing well either.
What are you guys doing?
So the girl you're dating is Subin?
Well...
Mom.
I was going to tell you after the final exams...
Subin.
What is this now?
What's this?
What are you doing?
Let go of her!
What is this?
What on earth is happening?!
What do you think are you doing?
(At Eighteen)
Can I ask you something?
That kind of thing...
...never happened.
I won't meet Subin outside of school again.
Even at school,
I won't talk to her.
In return...
...please let Subin have her freedom back.
I beg you.
This place is not a prison.
I'm not a prison guard.
You suffocate them and meddle with their lives.
You even censor and control their emotions.
Subin...
...let's get through this.
Even if it'll be hard.
At a time like this, we should focus on school.
That's what I'll do.
I hope you'll do the same.
I'm here for you.
I don't think I can get first place.
That being said, I'll need your help again.
I'll count on you and Dad.
Could you please drive a little faster?
Hello, I'm Choi Junwoo.
