And you believed this?
More than you believe me?
I see.
I did it for you.
I can explain everything.
Choi Junwoo.
Why did you do it?
You already know that the truth will be revealed eventually.
Didn't you think of what Subin would think of you?
Why do you think she got confused over a simple text message?
It's because she can't trust you.
The fact that you're a troublemaker who was forced to transfer...
...is always on her mind.
Know your place, Choi Junwoo.
Subin isn't someone you can freely like.
Don't you feel...
...guilty to Subin?
You hurt someone that you like.
Wasn't Subin...
...the only person you can truly open up to?
How could you do that to her?
Shut up.
Shut your mouth, Choi Junwoo.
What do you know?
What do you know?!
You fool.
You should've trusted him.
Ohje.
Do you know where Junwoo's house is?
What if...
What if he asks why I'm here?
No.
-Choi Jun... -Junwoo.
What are you doing up there?
Yes, Mom.
-Give that to me. -Here.
Why did you buy so much?
I need to make some side dishes for tomorrow.
For the restaurant?
Why do you have to make side dishes yourself?
I'm learning some cooking secrets these days.
The chef gave me a homework to do.
I should study hard while the restaurant is getting remodeled.
Junwoo.
Is something wrong?
What's with the sad face?
It's nothing.
Don't lie.
It's written all over your face.
"I'm having a terrible day."
"Don't bother me."
No. I'm not.
Let's go inside.
Are you at Chanyeol's house?
Do you know what time it is?
Hurry home.
Choi Junwoo...
...I'm sorry for not trusting you.
It's my fault.
For not being someone you can trust.
No.
I should've asked you about it,
but I didn't.
Because...
No matter how much I think about it...
...I don't think I deserve...
...to date you.
(I don't think I deserve to date you)
Are you okay?
What about you?
I think I'll need some time.
You understand that, right?
Don't take too long.
I'm sorry.
The mechanical energy of a moving object remains constant,
according to the law of conservation of energy.
You all like roller coasters, right?
-Yes. -Yes.
The roller coaster demonstrates this law the best,
in regards to the conversion between kinetic and potential energy.
Even though a roller coaster does not have an engine,
it can move up and down the track.
-This shows how energy is converted, -What's wrong with them?
-from one form to another. -No idea.
As a roller coaster moves from high place to a lower place...
...its potential energy decreases while its kinetic energy increases.
Let's see.
"A 10kg stationary object on the ground is vertically..."
Subin.
Why aren't you mad at me?
You know...
...that I lied to you.
Getting angry at you now doesn't change anything.
Right now...
...I'm trying my best to understand.
By putting myself...
...in my old friend, Ma Hwiyoung kiddo's, position.
"He probably has his reasons."
That's what I'm telling myself.
Subin.
Hwiyoung.
For once...
...I want you to carefully think about...
...how you really feel about me.
Your true feelings.
Are you doing this because you like me?
Or is it because of some other reason?
I thought I was going to suffocate to death.
What's up with you guys?
Exactly.
What's going on?
We just...
...decided to go back to being friends.
Really?
That's understandable.
It's not easy to get away from your mom's watchful eyes.
It might be a good idea to stay away for now, for Choi Junwoo's own good.
Soye, haven't you made up with Kitae yet?
How could she forgive him?
That Lee Kitae chose friendship over love.
What love? What friendship?
He's just devoted to his duty.
His duty as Ma Hwiyoung's butler.
What's wrong with you guys?
Are you openly ousting me?
Did you just realize that?
We looked for you, but we didn't see you.
It's over between you and Junwoo, right?
I guess it is.
Geez. We should really get rid of her.
This is so tasty.
Ma Hwiyoung did that?
Yes.
Isn't it unbelievable?
He's not even a child anymore.
Well...
...it is truly unbelievable and childish...
...but I guess it is understandable.
He probably lost control for a second...
Jung Ohje.
I'm just saying it's a possibility.
Just go talk things out with Subin.
Why are you complicating and over-analyzing things...
Yoo Pilsang!
Yoo Pilsang, seriously?
Didn't I tell you to stop?
Pilsang,
Junwoo has a sixth sense.
You should stop, okay?
Pilsang.
Instead of doing this to me,
go talk to Romi.
Go confess your feelings to her.
You think I'm crazy?
She'd kill me.
Would you rather die or go out with her?
Be more courageous. Even if it kills you.
Romi.
I like you.
I know. Don't like me.
I want to go out with you.
-No. -Don't just straight out say no.
Please think it over for a few days about letting me be your boyfriend.
Please.
Tell me your answer before the end of the school trip.
Gosh, Pilsang is pretty impressive.
What happened to him?
Choi Junwoo, good job.
"Be more courageous."
"Even if it kills you."
I thought it was a scene from a drama.
You're exaggerating.
I can't believe myself.
Who am I to give advice?
When I can't do that myself.
So?
So you've been calling him to find out about these things?
What were you trying to dig up?
The number you have dialed does not exist.
Please check the number and try again.
Mr. Oh, someone is looking for you.
Me?
Hi.
Oh, okay.
I would have returned it sooner, but I had a job interview.
Thank you for coming here when you must be busy.
I'm not busy.
I see.
The interview must have gone well. You look happy.
I failed it.
I'm sorry.
Then.
Have a nice day.
-Wait, Jimin. -Yes?
The other day
Yes, I got you a taxi the other day and brought your bag today.
If you want to treat me to a meal,
I'll decline that offer.
Then what about...
"Then, I'd like to buy you a cup of tea instead." No, thanks.
I'm a little busy.
Have a nice day.
That's not what I was going to say.
Food, drinks, tea... None of that.
"Actually, I'm interested in you."
"I'd like to ask you out."
If that's what you want to say, my answer is an even bigger no.
That's not it either.
The other day, you seemed to be having a hard time.
I just want to tell you to keep your chin up.
Everything will be all right.
Thank you for returning my bag. Bye.
It doesn't have to be today.
Gosh, dragonflies.
Alright.
I have some good news.
Our assistant monitor, Choi Junwoo's idea...
...has been chosen as the main event of the 11th-grade school trip.
Give him a round of applause.
Why is he so excited?
I know right.
Well...
While we're at it, let's enthusiastically prepare for it...
...win the games and aim for overall first place.
The first prize is an air purifier.
Let's do this, guys!
He must really want the air purifier.
He startled me.
I knew it.
Dad's clothes...
...are all gone.
Why would I keep old clothes? I've thrown them all away.
I still need them.
Then buy one.
How can I buy clothes that have your memories.
My goodness.
Let me take a look when I get home.
I wish you're this passionate when it comes to studying.
Hello?
She hung up on me. Unbelievable.
-Is it the outfit for the school trip? -Yes.
-That idea was suggested by my... -Geez.
I wonder who came up with it.
I'm sure it's a kid who doesn't care about studying.
You didn't have to trouble yourself. I could've just bought something to eat.
You eat out all the time.
Since you can't use your hand...
Thank you.
I'm sure you were popular with boys when you were younger.
Nonsense.
I had only one boyfriend.
It was Junwoo's dad. He was my first love.
I see. Really?
Didn't you date anyone else after you broke up?
Well, I did date a few men, but I didn't like any of them.
No one came close to Junwoo's dad.
-Thank you for the food. -Sure.
What will your son do about the school trip outfit?
He has his dad's clothes.
I kept one as a memento.
As a memento?
It's what your dad wore on our first date.
He looked so cool that day.
Nonetheless, they must have loved each other, right?
Back then.
At that moment.
Mom, can I come in?
Give me a second.
What is it, son?
What?
You're bothering yourself with that right now?
Subin is in charge, isn't she?
So you're trying to help her, aren't you?
No.
I'm the class monitor, so I should at least help them with some preparations.
Go up and study.
I'll figure out something for you.
What if your father finds out?
Hi, Mr. Park.
It's me, Park Geumja.
Can you make a suit for Hwiyoung?
Hurry. Go to your room.
Yes, sounds good. Something retro.
-I can't wait. -I'm so excited.
Right?
Kwon Daheen, are you going on your honeymoon?
Of course.
Seriously, don't overdo it.
Romi, you look pretty today.
What's this now?
Seriously. What's with everyone?
Hey, good morning everyone.
Is everyone here?
Hwiyoung, Junwoo, please do a headcount.
Okay.
You look great, Mr. Oh.
Hey, isn't that Jo Sanghoon?
You're right.
Didn't he go to Singapore?
Hi guys.
Sanghoon...
-...what are you doing here? -Hello, Mr. Oh.
I wanted to go on the school trip too,
so I hopped on a paddle boat and rushed over from Singapore.
What? What's going on?
I'll tell you later.
-Hey. -Hi guys!
-Jo Sanghoon. -Hey!
Okay. Let's get on the bus.
Don't get on the wrong bus.
Okay. Where should I sit?
I'll sit here.
Go.
Pilsang.
Just sit anywhere. Don't be picky.
Let's go.
Junwoo...
...sit here.
Look at that fox.
I'll sit in the back.
What's this?
Have you lost all sense of fear?
Let's keep moving.
Hurry it up, punk.
I'm going.
-When are we leaving? -Soon, I guess.
Look at this. Jo Sanghoon never did transfer.
He never submit the documents.
-Really? -Yes.
You're right.
So excited. So excited. So excited.
-Yes. -Let's go!
Be more excited.
-Yes. -I'm so hungry.
I'm so excited.
Let's go!
I'm sorry.
I'm hungry.
I skipped breakfast.
I have food.
You do? Let me have some.
It's so pretty.
Oh my gosh. I can't eat this.
What is that?
What is that? What is that?
Junwoo, what is that? I want one too.
Okay. Here.
Romi, take one.
I want one too.
Why do they look exactly the same?
Let me see.
They're the same.
What's this?
They really are.
Here, take this.
-What is it? -My part-time driver made them.
Thanks.
Share these with your friends. I made them last night.
I haven't had your rice balls in a while.
Thanks.
Hwiyoung and Junwoo, take care of your classmates.
-You can take care of it, right? -Yes.
There. Over there.
What?
So is this where Romi and I will be staying tonight?
Take your bags.
You came.
Don't get too excited.
I didn't come because of what you said.
Don't smile. Punk.
The view is really great.
Look at this.
What's the big fuss?
When do you plan to wear all of that?
I can wear them all.
How many is that?
Just make up.
Kitae is being very careful around you.
Look who's talking.
We didn't fight.
Neither did we.
Cheonbong High School students, please come to the main hall.
(Cheonbong High School - School Trip) Start!
♪ Dance merrily...
♪ ...and then stop.
Five people!
-Five people! -Five people!
Here! Come here!
Yes, we made it.
Okay, you guys are out.
Separate. Again.
Ready?
Start!
♪ Dance merrily...
♪ ...and then stop.
Two people!
Those who are left alone, please step out.
Those who are left alone, you're out of the game.
All right, great job.
Who's left?
Hi.
Daheen.
Here you were. I was looking all over for you.
Jung Ohje.
Can I keep this hat?
This is totally my style.
Hey.
How could you flirt with every single boy here?
What?
Daheen.
Give me that.
Did you just hit me?
No, I was just trying to take off the hat...
Hey, Hwang Romi.
You witch!
-Guys! -Let go of me!
What's wrong? What's the matter?
-Hey! -Let go!
-Romi! -Let me go!
Stop it!
Out of my way!
Hey, cut it out.
-Hey! -Stop it!
Hold on. Time out!
-Come over here! -Hit me instead.
Hey, stop it.
-Please, stop it! -Hey!
Get lost!
Guys...
...let's go get dinner.
No, thanks.
Daheen, open the door.
It's Ohje.
Don't open it.
Daheen.
I know you're in there.
What if Ohje gets caught for being at the girls' dormitory?
Daheen.
Ohje, move a bit.
Soye.
Subin.
Shall we go get dinner?
-I'll take it from here. -Okay.
You don't have to come tomorrow. I'm going to Japan for a business trip.
Okay, have a nice trip.
Songhee.
Why are you here?
I know Subin went on a school trip.
How can someone be so cold and indifferent?
She's so different from her daughter.
Oh, this.
-Hello, Ms. Yoon. -Hello.
I'm not getting a divorce. I won't get a divorce.
How many times do I have to tell you?
You know how important this period is for Subin. Are you crazy?
Subin will understand.
In order for me to move to the US next year,
I need to sort out the documents now.
Why? So that you can get married to that wench?
Songhee.
Let's stop with all this act.
Pretending to be happy parents in front of Subin,
and pretending to be a loving couple in front of everyone else.
I also hate doing this. You think I want to do this?
But I won't get divorced.
I will never get divorced until Subin gets into university.
Stop using Subin as an excuse.
Why don't you just beg for us not to split?
What?
You act like you're so much better than others...
...as if you're so cool.
I'm sick and tired of it.
Beg who? Do you think I still like you?
You did your doctorate with the money I earned.
And now you're living comfortably.
It's you who should be... Gosh, seriously...
You're the one who should be more honest.
I guess living with a woman,
who's less smart and competent than me, is perfect for your lifestyle.
Why can't you be honest and tell me that's the reason you're leaving?
Why are you asking if you already know?
Make your decision by next week.
If you don't, I'll file a divorce suit.
Seriously... Why?
Darn it!
What are you doing here?
You should go inside, Mrs. Yoon.
No, I'm fine.
Kwon Daheen.
It's a misunderstanding.
I'm not interested in Romi.
Then why did you stare at her?
I didn't stare at her.
About the hat earlier.
Romi just took it from me.
She always do whatever she wants.
I'm serious.
I'm not interested in any girl.
You're the only one I'm close with.
Really?
Then do you like me the most?
-What? -Do you like me?
It's the PE teacher.
That was close.
Daheen.
You're so cute.
I love you, Ohje.
I know how pathetic I am.
All I do is follow Hwiyoung around...
...and keep things in his favor.
I was delusional for thinking that I could become someone like him.
Kitae.
I know I'm a loser.
I'm such a loser, and I don't have the right to like you.
But I like you nonetheless.
I really like you.
I really like you, Soye.
But when you treat me so coldly like this...
...I can't stand it, Soye.
Get up.
I said get up.
I'll change from now on, Soye.
Make sure to take the snacks and drinks for your class.
-Class One. Over here. -Take one box each.
Ma Hwiyoung.
You're disappointed that I came back, right?
I don't care.
I know you do.
You must be really scared.
What?
I'm just kidding.
I'm so thankful to your dad.
He gave my dad a promotion...
...and let me continue to stay here.
What an angel.
How could I repay his kindness?
Let's have fun, my friend.
I'm looking forward to it.
Let's go.
Are you happy?
Are you satisfied now?
Would you be if you were me?
Subin is still having a hard time.
Hwiyoung.
Let me help you.
You should've called me earlier.
It's fine.
Hurry up.
We're here.
Hurry up and grill the meat.
We have a summer home in Santa Monica.
Santa Monica? Amazing!
This reminds me of the barbecue party we held in our garden.
Did you also just chatter away while you were there?
Without lifting a finger?
Hey, Hwang Romi.
You're such a big fat liar.
Didn't you say your dad is the director of Jaeyoung Hospital?
Hey.
Come with me.
Your dad is the director's driver.
How dare you tell such a lie?
You almost fooled all the mothers as well.
I knew it.
You always made excuses saying your mom couldn't come.
Your mom being a professor is also a lie, isn't it?
Pilsang, this is your chance. Go over there.
Why?
He doesn't want to embarrass Romi.
Seojin, what are you doing here? You're not even in our class.
-Talk to her some other time. -Let go of me.
Isn't it ridiculous? Her dad is not even a doctor.
Hey!
-Her dad is a doctor. -What?
Last time when my mom got sick, she was treated by Romi's dad.
How dare you make a scene after hearing some baseless rumors.
Kwon Daheen.
I don't need your help.
That' right. My dad is not a hospital director.
I lied a little.
What's the big deal?
Who was the one who said that I'm pretty and smart like my hospital director dad,
and said they were very jealous of me? Tell me.
Wasn't it you?
You shouldn't have lied.
You shouldn't have been fooled.
Blame yourself for falling for my lie.
Hwang Romi!
Don't follow me.
You're still awake.
Have some porridge.
Please just leave it there. I'll eat it later.
-Okay. -Thanks.
Then, I'll take my leave.
Okay.
Yeonwoo.
Well...
You don't have to work for me anymore after today.
But your arm hasn't healed yet.
I'll help you out a few more days after you get back from the business trip.
I can take a taxi.
I'd be too embarrassed to see you.
What are you talking about?
Let's just do that.
All right. Our next activity is...
...a truth hearing.
Let's begin!
Well...
Let me see.
Lee Kitae!
Kitae!
Come sit here.
Come on.
Guys, ask him anything you want, okay?
Well, you disappeared for a moment right before dinner.
Where were you?
I had a talk with Soye.
What did you two talk about?
I made a big mistake.
Hey, hey, hey.
What are you doing here?
Come join us.
I'm okay.
Call me when you need me.
I can help.
Are you sure?
Yes.
I actually need you right now.
It's so boring without you.
Put this away.
Let's go. Let's go.
Come join our truth hearing. Okay?
The most embarrassing moment of my life was...
...back when I was in elementary school.
I peed my pants in class once.
-What grade? -What grade?
I was in fifth grade.
-Fifth grade? -Really?
Unbelievable.
Do you have someone you're in love with right now?
-Gosh. -Seriously.
Hold on. It doesn't count.
The answer is already decided. It doesn't count.
Next question. Hurry.
Are you in love with someone who you shouldn't love?
Let's move on, guys.
Why? Let's hear his answer.
Forget it. Let's move on.
I wonder who it is.
What's wrong?
Hwang Romi!
I'll do it instead.
Why would you? Go back to your seat.
-Why do you care? -What are you doing?
-Fine. -I'll do it.
You do it.
Pilsang, sit down.
Go back to your seat.
You all saw it earlier, right?
Me admitting that I'm a big liar.
I don't deserve to participate in this truth game.
So I refuse.
-Daheen. -I'll pick the next one.
-Gosh. -What happened?
Yoo Subin.
Subin!
Yoo Subin!
Do you still like Choi Junwoo?
That was straightforward. So interesting.
Do you like him?
Please hurry up and tell us.
All right then.
There's no exception.
Five...
-Four! -Four!
-Three! -Three!
-Two! -Two!
-One! -One!
Ouch!
I ate too much today.
She's a real sociopath.
After being humiliated like that...
Moon Chanyeol.
I can hear you.
I'll never try to defend her again.
Who told you to?
Don't you try to defend me again.
Gosh, are you serious?
Don't do it. Don't.
Leg exercise.
She's so annoying. I don't want to do this anymore.
My stomach hurts.
(Choi Junwoo)
Subin...
...goodnight.
-Gosh. -Gosh.
Pilsang, don't do that.
-It's not me. -Don't do that.
Who is it?
Bring it on.
-Bring it on! -Let's just sleep.
It wasn't me!
Can you guys sleep?
Why are you still up?
Maybe it's because I'm away from home.
I can't sleep either.
It's driving me crazy.
Romi, are you crying?
Cry your heart out.
I take back for calling you a sociopath.
So you do have a conscience.
That Moon Seojin or Eun Saejin or whatever her name is.
(Cheonbong High School - School Trip)
All right!
Hello, I'm the MC of tonight's event.
The good looking guy of Cheonbong.
Cheonbong's crazy hot, nuclear handsome guy.
Come on.
I'm Oh Hankyeol. Hello, everyone.
Okay. Hwiyoung and Junwoo, hand out the light sticks to the others.
Okay. The first performance for the night.
Please welcome S-Light to the stage!
Applause!
Come to the front.
It's more fun if you come closer.
Who's next?
I think Godong will be singing next.
What? Godong can sing?
He sings well.
He used to be a trainee idol.
For real?
Godong, you're next. Get ready.
Okay.
Thank you.
Let's send Nam Seongwoo off with a big round of applause.
Okay. Next up is from Class 3.
Here's the outsider, Yoo Pilsang.
-Applause! -Is Godong not coming out?
Did he join at the last minute?
Hello. I'm the most desired guy in Cheonbong High, Yoo Pilsang.
You're handsome!
I'll be doing some impersonation tonight.
First, I'll imitate the vice-principal.
Godong, let's go.
Okay.
Are you nervous?
No, that's not it.
-I think I'm going to have diarrhea. -Now, I'm going to sing a song.
Diarrhea?
What do we do? You're up next.
Godong, hold it in.
You can do it.
-You can do it. -I can do it.
I can do it.
I can do it. I can't. I can't.
I don't think I can. I can't do it.
It'll come out while I'm singing.
You can sing a little, right?
You're good, right? I hope you're good.
Good luck.
Godong. Godong. Godong.
Godong!
Okay. The next performance...
...is by Godong.
He will take the stage.
-Please give him a big hand! -Come out, Godong!
Come out!
-Come out! -Come out!
-Hurry up! -Godong!
Godong!
-Godong, are you not ready? -Why aren't you coming out?
Godong is coming...
Why is Choi Junwoo coming out?
-It's Choi Junwoo. -That's not Godong.
-Is that you, Junwoo? -It's Junwoo.
-What? -Choi Junwoo?
In Godong's place,
Choi Junwoo will take the stage.
-Okay. Give him a round of applause! -Clap! Clap!
Choi Junwoo!
Why am I the one who's nervous?
Dance for us!
Nice!
Excuse me! You in the checkered shirt...
Are you all right?
Don't you feel wronged...
...living while not having a sense of presence?
I like you...
...too.
(Dancing In The Retro Night)
Yoo Pilsang...
...come with me.
If you haven't decided yet,
you can tell me later.
No, I'll tell you now.
Yoo Pilsang.
You're not my type.
Absolutely not my type.
So stop dreaming.
What must I do...
What must I do to make you like me?
I'll put in the effort. I'll do anything.
Don't.
You can try for 10, 20, 100 years...
No, even if we meet again in another lifetime,
you'll never be my boyfriend.
Find someone else.
Kitae.
Let's end things here.
What?
Let's break up.
What do you mean?
You...
...won't change.
And I'll keep hating that.
Hwiyoung.
For once, I want you to carefully think about...
...how you really feel about me.
Your true feelings.
Are you doing this because you like me?
Or is it because of some other reason?
I don't care about what I feel for you.
What's important is...
...I won't let anything be taken away from me.
Not by Choi Junwoo.
Junwoo.
I'm sorry...
...for not trusting you.
I'm sorry...
...for making you not trust me.
Stay by my side.
(At Eighteen)
You all had a good time, right? It's time to go home!
Shall we go?
I miss you every day.
I keep wanting to know more about you.
Don't worry about Junwoo.
He's doing fine.
I'll take good care of him.
I'm doing fine now.
I'm happy.
What has changed for you since we've started going out?
I keep looking in the mirror.
My reflection looks so excited.
Pat, pat.
I think we should take Subin out of the private lesson team.
-Mrs. Park. -Mrs. Yoon, what are you doing?
Did you do something to offend Hwiyoung?
I asked to have you be taken out.
Seeing you around is just too hard for me.
You're here.
