These stars were painted...
by Vincent van Gogh in 1889.
Although it's been 100 years,
they still inspire us to this day,
and they will continue to do so forever.
The artist may have lived a finite life,
but he painted a picture that will last forever.
Bestowing creativity and imagination to artificial intelligence...
is our goal.
Like Georg Cantor who established the infinite set theory,
solved many dilemmas...
and helped math advance in leaps and bounds,
we can dream infinitely...
and freely expand our realm of thoughts.
Infinity...
isn't in the far future.
Right now,
it is within us all.
(Cantor's Set Theory)
Thank you.
That was so touching.
I'm so proud of him.
It needs to be more than just touching.
His presentation was very different compared to those of others.
Baek Seung Yoo gave us the last speech for today,
and the Youth Mathematics Speech Competition has now come to an end.
Soon, we will announce the results and give out the awards.
(Episode 5)
Baek Seung Yoo. I liked his speech.
Would it be safe to call him a dark horse?
Nonsense.
I care for him very much.
That means Asung High School needs him.
I'll be off.
Long time no see.
Do you remember me? It's Noh Yeon Woo.
Oh, right.
Have you been well?
Did you instruct Baek Seung Yoo, the kid who just gave the speech?
- Yes. - I was impressed.
- Hello. - Oh, hello.
You need to look good for your photos.
Forget it. They haven't announced the results yet.
Are you kidding? You obviously won.
I mean, Seung Yoo's speech was utter nonsense.
It wasn't even good enough for the competition.
Good job.
Do you feel okay?
Well...
Yes.
Ye Rin, you did great.
I had no idea you were going to do your speech in English.
You had me startled.
It must've been hard.
We're going to announce the results. Please take your seats.
They're here.
We will now announce the results...
of the 2017 Youth Mathematics Speech Competition...
and give out the awards to the winners.
Don't be nervous.
You did great.
But what if I don't win an award?
Please come out as you are called.
Jung Won Min from Yeoil High School.
Ahn Jin Hui from Siah High School.
Me?
And...
please come out to the stage. Sung Ye Rin from Asung High School.
Congratulations.
We have one last contestant.
Honey.
Baek Seung Yoo from Asung High School.
- Please come out to the stage. - Oh, my goodness! Gosh!
Why is Baek Seung Yoo getting an award?
Two winners. I'm impressed.
Thank you.
The Minister of Education will be giving out the awards.
The nominee for the Prime Minister's Award...
goes to Jung Won Bin from Yeongyeon High School.
(2017 Youth Mathematics Speech Competition)
Now, it's time to announce...
the winner of the Presidential Award.
Minister, please go ahead.
The winner of the Presidential Award...
of the Youth Mathematics Speech Competition...
in the 2017 International Olympic of Mathematicians is...
from Asung High School.
Sung Ye Rin.
(2017 Youth Mathematics Speech Competition)
Congratulations.
We also have one more winner.
What's going on? There are two winners?
That's absurd. Only one person gets the Presidential Award.
As you all know,
only three people were supposed to win an award.
But the judges added an additional award.
Baek Seung Yoo from Asung High School?
Wasn't his speech more closely related to humanities?
Steve Jobs. He once said,
"Technology alone is not enough."
"What makes our hearts beat..."
"is technology combined with humanities."
I don't know about you, but when I heard Baek Seung Yoo's speech,
my heart was really pounding.
- He has a point. - I agree.
It's a special award given by the judges,
and the winner is Baek Seung Yoo from Asung High School.
(2017 Youth Mathematics Speech Competition)
One, two, three.
Ye Rin's the prettiest.
One, two, three.
The officials can go now.
This one's for students only.
Stay where you are.
Are you ready?
- One, two... - Stay there.
- Congratulations. - Thank you.
Mom's over here.
Over here.
Hello.
Well done.
One, two, three.
We're done.
Ye Rin, come over here.
Seung Yoo. Well done, son.
- Let's see the certificate. - Let's take a photo.
Sorry, Mom. Can I have some free time?
- Free time? - Yes.
Where is he going?
Honey, let me see.
Gosh. That was hectic.
Congratulations, Ms. Ji.
Thank you.
You did well. Two of your students won.
Good job.
I'm surprised. I didn't expect it.
After they're done here,
are you up for a meal with the minister and vice-minister?
- A meal? - Excuse me.
Hello, Vice-minister. Sure.
I'll call you.
Yes.
- Ms. Ji. - Seung Yoo.
Can we talk?
Hello, I'm in my second year at Asung High School,
and my name is Sung Ye Rin.
I'm so honored and moved to be given an award.
Earlier on, I couldn't breathe.
I was able to breathe after I saw these numbers.
I felt dizzy and I couldn't see well,
but I clearly saw the symmetric sequence.
My ears felt weird and I couldn't hear,
but then I heard your voice.
That's how I was able to solve this.
Seung Yoo.
Why you couldn't breathe,
or see or hear properly.
Can you tell me?
That will be fine.
Where did he go?
Honey, try calling him.
Jin Ho was...
my only friend.
In a place where I didn't speak the language,
he was the only person to reach out to me.
(At MIT, 8 years ago)
It's a gift.
I'm Yu Jin Ho. I'm Korean too.
You solved it this way?
You really are...
special.
Help me out again.
I thought he meant it.
That was stupid of me.
So, we can calculate the image of d2 like this,
and therefore, we can get this.
So, you're saying that the cohomology class...
of the central extensions T-sharp is zero?
What about the edge map of the spectral sequence?
The edge map...
Let's see. The spectral sequence of the edge map is...
I had no idea that...
my solution from that day...
ruined the years of work he had put into his thesis.
Jin Ho!
No.
Jin Ho!
Jin Ho.
The call will be transferred to...
You're exhausted, aren't you?
There's nothing we can do. You still have to go to class.
Okay.
You did well. You know that, right?
I'll pick you up later.
Manager?
It was an arduous day for both of you.
This isn't much.
My gosh, what a precious gift.
I must put it on a pedestal at home.
Not at all.
- Shall we get the party started? - Sure.
- Did you send her off? - Yes.
Ms. Noh, have a drink.
I saw you talk to the Educational TV people.
The specialized school judging is coming up.
We're working on a program for Asung's Advanced Math class.
Gosh, that's great!
How about a toast?
- Well done, everyone. - Well done.
Good job.
While working on his thesis, Jin Ho...
must have fought terribly.
Against numbers, against time, and against himself.
It's a desperate fight that is...
solely one's own.
No one can help...
or get in the way.
I don't think...
Jin Ho resented you.
He just fell in love...
with that problem.
With all his heart.
What are you doing here?
- Why didn't you answer your phone? - My phone?
- I didn't hear it. - What were you doing?
As you see, I was talking to my student.
Are you done?
Congratulations, kid.
Can she go now?
Sung Jae.
You should go, Ms. Ji.
I put you through a lot today.
Goodbye.
I made up an excuse and turned down the dinner.
I thought you'd be uncomfortable.
Sorry about earlier.
I was overly sensitive.
But do you really not know?
- What? - That he likes you.
It's possible. It's common at that age.
First love, puppy love, things like that.
Don't say that.
You don't know him.
Do I have to?
You know,
I may not know him, but I do know you.
How could you not care about a student who's gifted in math?
I know. However...
You can't hide how you feel.
Everyone can see it.
You should be careful. Especially after what happened.
If a rumor gets repeated, it becomes the truth.
If a coincidence repeats itself,
it becomes intentional.
I understand.
I'll be careful.
- Here's your food. - Thank you.
(Award of Excellence)
- Have a nice day. - Have a nice day.
How many did you get?
I bet I got a lot.
Ye Rin, you can't go home until you solve what you got wrong.
Okay?
You can't solve it like that.
I'm using the formula.
Not the formula.
Look at the shape of the clock.
Since n appears less,
you should solve for n.
So this is the equation that you get.
(Move to Secure Folder)
(Secure Folder, Enter your PIN.)
(Moving to Secure Folder)
Calculus.
Yes. A pebble.
This little stone is also the source of a spring.
If you get nervous, hold that tight.
You can't hide how you feel.
Everyone can see it.
(Delete)
Come early tomorrow.
Educational TV is coming to do a story.
Asung High School produced two winners...
at the Youth Mathematics Speech Competition!
And who are they? They are...
They are...
none other than Sung Ye Rin and Baek Seung Yoo!
Applause!
He's here!
- Baek Seung Yoo! - Go!
Applause!
Aren't you Ms. Ji Yoon Su?
Congratulations. I heard two students from Asung High...
won at yesterday's Mathematician Olympics.
You were their teacher, right?
Are you doing a story?
No, it's nothing that big.
I was curious.
I heard you taught students who won the Olympiads...
at an ordinary school before. You did, right?
You really are amazing.
What's your secret?
I'm sorry, but I have to go.
Don't be like that. Tell me.
If you'd share a brief summary of the guidance you gave them...
I'm sorry. I have nothing to say.
You produced a winner of the Presidential Award.
In Asung's math club, Calculus,
we add humanities and artistic sensitivity...
to provide a collaborative method of teaching...
the students math.
The result of that is the speech that Baek Seung Yoo gave,
which won the judges' special award.
Can you tell me what the picture is?
What is that picture?
This is one of Ms. Ji Yoon Su's special class for the club.
They solve the students' everyday problems...
using mathematical methods.
Let's have Ms. Ji explain it in detail.
Thank you.
Please send us a preview tomorrow.
I will. I'll be in touch.
- Thank you for coming. - Goodbye.
- Goodbye. - Goodbye.
(Assemblyman Sung Min Jun)
- Hello? - We're in trouble.
What is it?
I got a call from the chairman of the Math Society.
He said a reporter came by this morning.
From where?
From MBS Local News.
They asked for the details...
regarding why they suddenly created a youth competition.
It's airing today. What should we do?
I'll find out if they went to see Professor Cha as well.
Check the Ministry of Education.
Yes.
You didn't tell anyone that Ye Rin was taught...
by Professor Cha, did you?
Of course, not. Why would I? I'm not an idiot.
(Suspicion of special treatment for Assemblyman Sung Min Jun's daughter)
Everything began with this one photograph.
The student in this photograph received the Presidential Award...
at the Youth Mathematics Speech Competition...
of the International Mathematician Olympics.
She's the daughter of Assemblyman Sung Min Jun.
Was there a problem with her win?
She participated in a symposium immediately before the competition.
It turned out to be related to the research...
by artificial intelligence researcher Professor Cha.
("Was there special treatment during preparation?")
As you can see, the content of her speech...
is nearly identical...
to the application of the AI face-recognition program...
being developed by Professor Cha's team.
What's more shocking is this.
That Professor Cha was a judge at the competition.
So there was preferential treatment in preparation and judging.
It is definitely suspicious.
The student must have known this would become an issue...
and stated that she prepared for the competition...
at the school under the guidance of her math teacher.
However, based on my investigation, it was not true.
Whatever. How could you know that?
If you'd share a brief summary of the guidance you gave them...
I'm sorry. I have nothing to say.
Didn't you teach the winner of the Presidential Award?
("Didn't you teach the winner of the Presidential Award?")
The teacher refused to talk about it.
As an assemblyman with a child in high school...
When did Ms. Ji give an interview like that?
That idiot.
You didn't know it was an interview?
No.
I think you should give an interview to clarify your position.
What do you mean?
Are you telling me to say I was in fact her adviser?
You have to.
- I'll talk to Assemblyman Sung... - No, don't.
Do you think lying is the best thing for Ye Rin?
She's hurt more than anyone right now.
I need to think about what's the best thing to do...
for Ye Rin's sake.
- Is the TV show about Ye Rin true? - Her dad pulls strings?
Wow. Talk about an assemblyman's flex.
Will she lose the award?
I knew it.
Hye Mi is a conniving witch.
Like husband, like wife. I knew she was shady...
ever since I saw her being arrogant because he was an assemblyman.
If that's true,
they should cancel the Presidential Award.
Wouldn't that mean Seung Yoo will get it instead?
Hold on. Where's the award certificate?
(Cancel the award!)
(Dig deeper for more corruption.)
(Want a Presidential Award? Have an assemblyman dad.)
(Did you watch the program?)
Did you watch the program?
I was worried.
Seung Yoo, will you do me a favor?
(Seung Yoo, will you do me a favor?)
This won't do.
Let's skip school today.
No. I have a performance assessment today.
Then should I go in with you?
Don't you realize you always make things worse?
That brat...
Sung Ye Rin is here!
- Ye Rin! - You're Sung Ye Rin, right?
How did you end up doing volunteer work for IAIT?
Are you sure you prepared for the Olympics at school?
Did Professor Cha help...
- Wait! - Stop!
Ms. Ji wants to talk to you.
I was aware of the help you received for the competition,
and I didn't think it was fair or right.
I didn't do that interview on purpose,
but I didn't lie either.
So what's your point?
There are many ways to live life.
Sometimes, you can take shortcuts...
and go faster than others.
But if you cross the line and drive on the shoulder,
you could hurt others.
Most importantly, you will hurt yourself.
Are you trying to scare me?
I'm warning you not to take the wrong path.
Ye Rin.
You're capable of doing well, and you're a smart kid.
But if you still feel anxious, let's try to solve that together.
I'll help.
What did I do wrong?
I don't understand...
what it was that I did wrong.
You think the preparations for the competition were unfair...
because the others didn't get the same opportunity as I did?
How is that my fault?
Are you okay?
I don't feel bad at all.
You're more privileged than I am thanks to your talent.
(Director of School Affairs Noh Jung Ah)
(The reports at MBS have noticed...)
(Assemblyman Sung Min Jun Denies All Allegations Regarding His Daughter)
(Assemblyman Sung Min Jun)
- Did you read it? - This will do.
Avoid the press or any other kinds of formal events for now.
(Assemblyman Sung Min Jun)
What are you going to do about Ms. Ji?
I'll warn her and make sure this doesn't happen again.
Did you look into the reporter?
Yes, I did.
But I couldn't find any specific connections between us.
- Okay, let's hang up. - Wait.
The midterms are coming up.
And?
You're going to help, right?
Help with what?
I mean, the usual stuff.
The list of expected questions for all the major subjects.
Assemblyman Sung.
Yes?
I've been cutting you a lot of slack.
Yes, I know.
I have something to tell you.
- Ye Rin, are the rumors true? - Hey, Ye Rin. Daddy's girl.
Ye Rin, it must feel great to have a father who's an assemblyman.
Ye Rin, you looked great in the photos.
- Look at her. - Hey, that's Ye Rin.
Make way for Ye Rin.
You'd like to talk to her parents?
Yes, I'd like to have a talk with Ye Rin's parents.
Is there a problem with Ye Rin?
She asked me what it was that she did wrong.
I think that's the problem.
Ms. Ji, are you trying to make a big deal out of this?
I want to set things straight...
before things get completely out of hand.
"Set things straight"?
Set things straight starting from where?
Most of our students at Asung High School...
went to the same kindergarten, elementary, and middle school.
They were born into similar environments...
and received similar education.
These kids will get into prestigious universities.
They will either inherit their family businesses...
or find jobs based on what their parents want...
and become the leaders of this country.
Their paths and future have already been set...
the moment they were born.
So I'm starting to wonder which part of that entire process...
you plan to set straight.
I don't interfere with the way you teach the kids.
The parents also don't comment on your unusual teaching methods.
So you have no right to interfere with the way they raise their kids.
I'm setting you straight before you cross the line...
and get things out of hand.
If you cross the line,
I won't be able to help.
Are you enjoying this?
Are you having fun watching me suffer?
Did you forget? I told you to beat Seung Yoo.
I don't care how. What matters is that you beat him.
But tell me something.
You didn't cheat to get the highest grades as well, did you?
What are you talking about? No way.
Good. That better be true.
Come on. Isn't it obvious?
She obviously got help from the Institute of AI Technology.
Yes, there's no way a high school student...
can work as an intern there without her parents' connections.
Ye Rin's mother can be very cunning.
She never shares high-class information with us.
- She only keeps it for Ye Rin. - You're right.
Exactly.
I see Ye Rin's mother isn't here.
She's probably not in the mood to drink tea with us.
We barely get to see her these days.
I guess they haven't canceled Ye Rin's award.
I guess it's nice to have a father who's an assemblyman.
Seung Yoo must be upset.
If it weren't for Ye Rin, he would've won that award.
- She's right. - I agree.
My point exactly.
Hee Seung, join us for a moment.
Sit down.
How does Seung Yoo study math?
Give us some tips.
Gyu Yeong gets the highest math grades.
You don't need any tips.
We're sorry for being so ignorant.
How does he study these days?
Which academy does he go to?
Academy? Well, we're still looking into it.
Then why don't we gather our kids and have them study together?
My goodness, that's a great idea.
Let's do that.
I... I guess we can do that.
- What's wrong? - What's the matter?
I don't know. She keeps screaming, but the door won't open.
- Try to open the door. - What?
Ye Rin!
Ye Rin.
Oh, my goodness. Ye Rin.
What happened to your hair?
You need to pull yourself together.
The midterms are coming up.
What about the list of expected questions?
I don't think you'll get that this time.
Instead, we'll hire tutors for every subject.
What do you mean?
I'm not getting the list?
What am I going to do?
I need to get the best grades in my year.
What if my grades fall?
Ye Rin.
I want you to fix this. This is all your fault, Mom.
Do what you need to do to fix this!
Honey, can you ask Ms. Noh one more time?
It won't be easy.
If I get on her nerves, it might backfire on us.
Then what are we going to do?
I'm worried that something might happen to her.
Why did she have to get herself in trouble like that?
She should act carefully right before her wedding.
- Yoon Su didn't mess up... - I guarantee you.
You two will fight a lot once you're married.
Even if you marry someone with the same values,
married life is tough.
You and she have different backgrounds and habits.
You have nothing in common.
That's why I like her.
What? My gosh.
(Groom Ryu Sung Jae, Bride Ji Yoon Su)
The wedding invitation's out.
You enjoy it all you want.
Don't just grin and remember what I said.
You must keep a tight rein on her.
Okay, sure.
- Ms. Ji. - Hello.
I'm so tired.
There's a lot going on, inside and outside the school.
They say bad comes with the good.
I was pleased that two of our kids got a huge prize,
and now there's this uproar.
(Ryu Sung Jae, Ji Yoon Su, We're getting married!)
My gosh. Ms. Ji.
Are you getting married?
Yes.
My goodness. How could you?
Why didn't you say so?
Congratulations.
Thank you.
So, how is Ye Rin doing?
Well... She'll be fine.
Don't worry too much.
Did you ask to see me?
Ye Rin.
It has been tough on you, hasn't it?
You worked hard.
I'm sorry this is how it worked out.
But then, you are not to blame.
It's all on your parents.
What about Ms. Ji?
Is she not to blame?
Yes, Ye Rin.
That's it.
That attitude. I like it.
It's just right.
This is what you should've said.
The upcoming midterm exam...
will be an important opportunity.
I trust you will do well.
I will, Ms. Noh.
Sorry.
- Ms. Ji. - Seung Yoo.
- Give me that. - It's fine.
I'll carry it.
Thank you.
Sure.
Hey. Will you stay after school?
No, I have another class.
Our homeroom teacher just said...
Ms. Ji was getting married.
Her wedding invitation's out.
She suggested the math club throw some kind of party.
Why should we do that when the midterms are coming up?
Will you go to her wedding?
Who's here?
Sung Ye Rin's mother Yu Hye Mi.
She wants to see you.
Shall I let her in?
Tell her I'm busy.
Pardon?
I won't see any parents for a while.
Do you get what that means?
Yes, I do.
(Director of School Affairs, Noh Jung Ah)
Hello, Vice Principal. Can I see her?
She is...
- busy with work. - Pardon?
You can meet her some other time.
Vice Principal. This is not like you.
She has a lot to deal with.
Goodbye, then.
Then pass these to her for me.
I made some candied ginseng.
She told me not to accept anything. Off you go.
Goodbye, then.
But...
Ms. Ji!
- Ms. Ji. - Oh, no.
Ms. Ji.
Are you okay?
My ankle.
Seung Yoo.
Get on my back.
What's that about?
I'll put you in a cast.
Tell me if it hurts.
Okay.
Who came in with Ms. Ji Yoon Su?
Are you her guardian?
- No, I'm... - I'm her guardian.
- Fill this in. - Okay.
What happened?
She fell off her bike.
- Where is she? - She's with a doctor.
Here you go.
Follow me.
You can go.
- Come in. - Yoon Su.
What happened?
- How is she? - It's not a fracture.
It's a pulled ligament.
Are you okay?
Sorry. Were you very worried?
Seung Yoo.
Are you all right?
Yes, I'm fine.
The brakes on your bike were broken.
If someone did this on purpose, you should look into it.
Send her this photo...
and go home.
I will deal with it.
Yes. Thank you, Seung Yoo.
It's late. Go home.
Let's go.
Ye Rin, what are you...
My gosh.
Goodness. What are you doing?
I can't concentrate in this mess.
How long will you keep saying that?
What are these?
That's for ADHD, isn't it?
Where did you get these?
Don't bother!
- Give them to me! - No!
Let go!
My gosh. Why are you like this?
It's all your fault!
If you'd given me a better brain,
I wouldn't have to take pills to study.
And I wouldn't have to...
worry about not coming first whenever there's an exam.
Your brain is just fine.
And we support you.
So you can get good grades,
Mom and Dad do all sorts of things for all sorts of people!
Do it again, then!
Make it so I come first in my year.
Or don't care whether I take pills or not.
How is it?
It's fine.
We should call the police.
- The police? - Whoever did that...
had the intention to hurt you.
What if it were one of the students?
I can't just report it.
First, I must find out who did it.
Then let's check the security footage.
It was in the parking lot, right?
I'll go and check.
You won't be able to see anything in the dark.
Even if you do, there's no one there at night.
I'll have a look tomorrow morning.
Make sure to. You can't let this slide.
Okay?
Okay.
He got a little too into it.
- Who? - Baek Seung Yoo.
Him.
I told him to leave, but he stayed.
I guess he was worried.
Get on my back.
I really enjoyed that.
Kim Han Chul. Former news bureau chief at MBS.
He's a professor of media marketing at Sangchun University now.
Sangchun University?
Who are you?
What was that?
You should pop some champagne. Congrats.
That was a pretty successful blow.
Your uncle.
The former news bureau chief at MBS that you planted...
on the Sangchun University president.
In front of the bureau chief is the reporter Cho Yoon Ah.
I was impressed.
Let's do this...
until we're both covered in mud.
I could've exposed more if I wanted to.
Asung's unfair admissions,
the corruption during the process of becoming independent,
and all the shady money supposedly for the school's development?
Exactly. Why didn't you expose me?
Because you would die along with me. Right?
You're right. That was why I sent a warning first.
I see. First.
I don't know what will come next...
if the warning goes ignored.
So stop siphoning so much.
I won't let you misuse Asung Foundation's name...
to pad your wallet anymore.
Don't pretend to be a fighter for justice.
I know you.
If you can't have it, no one can.
That's your selfish attitude.
Yeon Woo.
What are you so afraid of?
You're the true leader of this family anyway.
So what were you doing?
You should've shaped up before Father called me.
(Award of Excellence)
What's with the bike?
Because I need it.
Your midterms are coming up, right?
How is it going?
I'll see you later.
Gosh. Isn't it heavy? Want me to help?
How could this happen so close to the wedding?
Sorry for bugging you.
There were no cameras in the parking lot.
What do you mean?
Thank goodness my car was there.
We can check from yesterday afternoon, right?
Here it is.
Go in first.
Hey.
Ms. Ji says to come to the counseling room.
Did you do something?
I heard you and Ye Rin were close ever since you were kids.
I would feel mad betrayed by you if I were her.
You faker.
And you really haven't changed.
Do you like Ms. Ji that much?
Watch it.
It was fun watching you running with her on your back.
(Counseling room)
Come in.
Have a seat.
What is this?
A questionnaire that gauges learning anxiety.
I extracted questions just related to math.
Let's see which parts you struggle with the most.
(Learning Anxiety Survey)
I'll analyze it and help you improve the areas you struggle with.
Let me know when you're done.
Are you testing me?
You know, don't you?
- What? - What I did.
I know you didn't give that interview...
because you hated me.
I didn't do it because I hate you either.
I know.
Extreme insecurity, stress, and anxiety...
drove you to do that.
So, let's figure it out...
what that insecurity and anxiety inside of you are.
Don't you think you should find out at least once?
(Counseling room)
Did you find out?
(Yes.)
Yes.
Who was it?
The kid we suspected.
(Learning Anxiety Survey)
(Very much)
Really?
He carried her on his back and ran, all frantic.
My gosh. Does Seung Yoo like her that much?
I guess Gyu Yeong wasn't mistaken.
He said he thought there was something between them.
Seung Yoo is one thing.
- She should've been more careful. - I know.
What are you talking about?
Seung Yoo likes whom?
Are you okay?
Ms. Ji!
It was me.
Ms. Ji's bike.
I bet you already knew.
But why haven't you said anything to me?
Why are you telling me?
Because it was your fault.
You changed...
after Ms. Ji came, but everything was fine...
until then.
Did you have to do this?
Did you have to make me so anxious and nervous?
Like I told you before,
I'm not trying to beat you.
I'm not trying to hurt you either.
Are you saying I shouldn't blame you?
Don't punish yourself because of me.
Don't let your anxiety and distress...
destroy you.
You need to stop.
Then back down.
You promised that you won't compete with me.
Keep your promise.
I'm sorry.
I don't think I can keep that promise now.
It's not because I want to beat you.
It's because I want to become a better person.
Is it because of Ms. Ji?
Here you go.
Did you take these photos? I really liked them.
Thank you.
Oh, wait. I think it's going to rain.
Ms. Ji, can we meet right now?
Just come out to the first floor.
I'll meet you there.
(Sung Ye Rin)
(Ryu Sung Jae, Ji Yoon Su, We're getting married!)
(Baek Seung Yoo)
It was when I went to Jeju Island with Professor Cha.
I saw them together.
Seung Yoo.
Why did you walk in the rain?
What's the matter?
- Seung Yoo. - You told me...
not to fall in love.
What am I supposed to do...
if I can't help it?
Why are you showing me this?
I'll give that photo to you.
I think it might be of good use to you.
Instead...
Seung Yoo.
What are you talking about all of a sudden?
What am I supposed to do?
What if I come across a math problem that I can't help but love?
What if I want to solve it like crazy?
(Melancholia)
What's the matter with us these days?
Why does it feel like something's wrong?
- A special tutor? - I've heard strange rumors.
I thought about...
what you said.
Please forgive her.
Please forgive Ye Rin just this once.
You must be out of your mind.
I heard there was something going on between you two.
What's the point of living in paradise where everyone is happy?
Don't mess with Ms. Ji.
I'm going to protect her so that no one can hurt her.
