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?
I don't understand...
what you mean.
This is a gift.
Why are you showing me this?
I'll give that photo to you.
I think it might be of good use to you.
Instead...
Instead what?
Tell me.
Help me prepare for the midterm exams.
My goodness, Ye Rin.
Ye Rin.
Your pain has made you more mature.
You learned how to bargain.
I like what you have.
But I won't buy it.
Ye Rin.
A deal...
isn't made when you need insurance.
Like you said, one day, this will come in handy.
Let's talk about it then.
That photo.
Did you show it to anyone else?
No.
Good. Keep it well hidden.
Until the time comes for you to use it.
(Episode 6)
What if I come across a math problem that I can't help but love?
What if I want to solve it like crazy?
Can I really show everything?
- Hello? - Are you home?
(Ministry of Education)
I'll pick you up on Sunday at 11:30am.
What for?
You forgot again?
We're having lunch at my parents'.
Right.
- Okay. - You sound tired.
See you on Sunday.
(We are getting married.)
Assemblyman Sung's daughter attends Asung High School.
Yes.
I saw your interview on TV.
You must always watch what you say.
Sung Jae will do great things too.
The second daughter of Jangsung Finance's chairman...
and Hyunsung Daily News' chairman's two sons go there too.
You should keep an eye out for them too.
Father.
Do you know how I got hurt?
One of my students sabotaged my bicycle.
But I think...
it's not the bike that's broken.
I'm worried the student is.
What is your point?
I'm saying that the parents' influence...
could work against the child's favor.
How do you think you'll feel when we have a child?
Won't you want to do all you can for its sake?
Doing all I can to love my child...
is different from putting my child first...
at the expense of other children.
Let's not be so sure about it.
Instead of being just Sung Jae and Yoon Su,
when we become someone's mom and dad,
we'll find out only then how we really feel.
What's the matter with us these days?
Why does it feel like something's wrong?
Is it always like this before the wedding?
Yoon Su.
- Yes? - I always felt relaxed around you.
But these days...
I don't.
Do you have anything to say?
Not really.
I guess I have a lot on my mind right before the wedding.
I wonder if everyone feels this way.
- Will you go home? - I'll visit my dad.
To give him the wedding invitation.
Sorry.
You can go.
I have to take the minister to a Cheongwadae function.
Then I'll get out here.
- Drive safely. - Okay. Call me.
It's different.
It's a method I've never seen before.
What's your next challenge?
Ms. Ji made me love math.
There is no math without Ms. Ji.
I love...
Ms. Ji.
You will prove this?
Proving it won't change anything.
I just...
want to show...
my proposition is true.
A proposition that doesn't need to be proven true.
How empty.
(Salesio Sanatorium)
(2017 Congress of Probability Theory)
(Saturday, October 28, 2017)
(We wish to invite you, Mr. Baek.)
How about submitting your solution to the symposium archive?
- To the archive? - Yes.
I believe your approach was never used before.
You should give it a try.
(2017 Congress of Probability Theory)
(Salesio Sanatorium)
Mom.
Dad.
I'm getting married.
(We are getting married.)
Let's meet in the math lecture room shortly before class.
You went to see...
my father on Sunday. Right?
- Yes. - Thank you...
for showing him your proof.
I was invited to the Congress of Probability Theory...
when I uploaded my proof on the archive as you said.
Is that so?
That's great.
I thought about...
what you told me.
Yes.
There are math problems you can't help...
but want to solve them and fall in love with them.
When you continue to study math,
you are bound to come across these problems.
But...
when you give all of your energy to one thing,
it also means you are losing yourself.
It will destroy and hurt you.
What if I find...
a math problem that's worth all of this damage?
Don't look for it.
The problem will find you...
when you become strong and stable enough that you will not get hurt...
while trying to solve it.
I believe that one day,
you will achieve that.
I appreciate your present,
but I cannot accept this.
Hey, Gang Jin.
You're dead meat.
Hey, I'm sorry.
- Who's in for some snacks? Me. - Me.
- And you. Let's go. - And you.
Here we go.
(Overview of Frequent Exam Questions)
Gosh. Darn it.
I have to follow my gut. Studying won't help me.
That's my expertise.
Why did you stop?
- What is it? - Go without me.
- Okay. Come on. - Hey, I forgot my wallet.
Don't forget your stuff, man.
Gosh. You came running right away. Are you scared?
Do you still like Ms. Ji?
She's getting married. Get a grip, man.
- Give it back. - Does she also know...
that you like her?
What? Did you tell her?
Gosh. Are you nuts? You're out of your mind.
Where's the frame?
Too bad.
She's getting married in two days.
If the other kids saw it, she'd be so embarrassed.
Chill. I'll give it back to you.
If you do something for me.
Give up.
Your sophomore GPA is low anyway.
There's no point trying now.
What is it that you want?
Don't score high on your midterms.
Then I'll give it back. If you do score high,
I'll hang it up in the classroom.
You jerk.
Go ahead. Punch me again.
I'll answer this time when they ask why you punched me.
I'll tell them you punched me because you like Ms. Ji.
You have it until tomorrow.
Think about it, and let me know.
Hey, Jang Gyu Yeong.
Listen up.
Do not put Ms. Ji in a tight spot.
What if I do?
I'll protect her, so no one can hurt her.
How?
Who do you think has the most power in our world?
The top student.
The student with the highest grades.
The midterms will be the beginning.
The season of verdure is very much evident in our day-to-day lives now.
You must be very busy preparing for the midterms.
But I would appreciate it if you could stop by my cafe.
How is Seung Yoo these days?
His midterms are coming up soon.
And the club is on a break for now.
So I wasn't able to check up on him.
- Well... - I still can't believe...
if this is really happening. It feels so surreal.
You know, he stayed up all night to study for the tests.
- Is that so? - This is...
all thanks to you. There really aren't any words...
that can describe how much I appreciate your influence on him.
I didn't do anything. It's...
Kids at his age...
study hard when they meet a teacher they like,
so they can make a good impression.
My son tends to focus on only one thing.
When he gets hooked on something,
that's all he'll pursue.
I hope you can guide him properly as his teacher.
The midterms will be held soon.
- You don't know this? - I don't.
- Do you know what pi is? - What pie?
The only thing I want to figure out is what you want.
Go back to your seat now.
Okay.
(Students are not allowed during the exam week.)
I would like to share a few reminders about the exams.
I expect all the departments to review the questions thoroughly,
so there won't be any errors in them.
And please pay close attention to its security...
the moment you put together your exams until the exams are over.
- Ms. Lee. - Yes?
Can you take a look at this draft?
Give me a second. Let me just wrap this up first.
Come on, I'm in a hurry too. I have a class next period.
If you're done reviewing them,
can you ask one of the faculty to take care of the rest?
Sure. Excuse me.
Yes?
Can you sort them out by class and grade...
- and put them in the envelopes? - Sure.
The kids might come in,
so finish before their break starts.
Sure.
- What's the matter? - I included the file.
But it won't work.
(The 2nd Semester of 2017, Midterm Exam Answer Key, Junior)
(Teacher Han Myung Jin)
Stop taking selfies.
I told you to stop checking out social media.
Are you here to work out?
Okay. Have a good workout, honey.
Gosh. Why did she...
Ye Rin.
I got it. Here.
- What is this? - I found a way.
Did you really think I'd just give up?
Hurry up and memorize the answers.
According to Mr. Han,
the math test is going to be really hard this time.
Memorize everything, okay?
- There are a few more pages. - Honey, can you get me a drink?
Okay, just a second.
Good luck.
(Therefore, the answer is the square root of 2.)

Pass on the test papers to the person behind you.
(2nd Semester Midterms,1st period: Math, 2nd period: Korean History)
Don't look sideways.
Just quietly pass the test papers.
Did everyone get the test?
Then let's begin the test.
(Subject: Math)
(Subject: Math, Name: Baek Seung Yoo)
(Subject: Math, Name: Sung Ye Rin)
She did well.
(Midterm Exam: Math Answers)
Gosh, this is a disaster. I totally failed the math test.
- My gosh. He got everything right. - He got everything right?
Seung Yoo, you crazy punk.
How did you get everything right?
- Let me see. - He got a perfect score?
- He got a perfect score. - Is this for real?
He's my friend.
- My gosh, this is unbelievable. - You did great.
Seung Yoo.
I can't believe this.
My score is so bad.
This is amazing.
(Question 4 Short-answer)
- How did you do? Did you do well? - I got one wrong.
- Why? - The answer is different.
What do you mean? That's impossible.
Are you sure you didn't make a mistake?
I didn't make a mistake.
But the answer is different.
Gosh, you startled me. Why were you so surprised?
Ms. Ji wants to see you.
What do you mean you changed the answer sheet?
The number four short-answer question.
We forgot that we changed a few numbers.
I didn't know until Ms. Ji told me that the answer was wrong.
When?
It was right after you went home yesterday.
You wanted to see me?
Yes.
Good work on your test.
I graded your test paper, and you did well.
But...
about the number four short-answer question.
How did you get this answer?
Why?
This math problem can't be solved this way...
based on the given numbers.
You were given the number "13" on the test,
but you solved it using the number "eight."
Can you explain this to me?
I guess I made a mistake.
It's natural to make mistakes.
- But it doesn't make sense... - Ms. Ji.
Can we talk?
Pardon?
I need to talk to you.
You may go. We'll talk about this later.
Why didn't you discuss anything with me?
- What? - You changed the answer...
for the number four short-answer question yesterday.
Even if you found an error,
you still should've discussed it with me.
I thought it was more urgent to fix the answer sheet...
because the test was on the following day.
Why did you want to see Ye Rin?
Weren't you talking about the answer sheet with her?
I had a question about her test paper. I'll be off, then.
From now on, discuss everything with me.
We teach the same subject, so please try to communicate.
What?
What do you mean?
Are you saying Ms. Ji knows?
I'm not sure if she knows for sure.
But it's possible that she might raise an issue about it.
If she ever asks,
tell Ye Rin to tell her that it was a mistake...
no matter what happens.
What's the matter with you?
I can't believe she changed the answer sheet...
after you gave it to us.
- What's this about? - My goodness.
- Who's on the phone? - No, wait.
- "Han Myung Jin"? - Honey.
What did you just say?
He gave you the answer sheet?
Honey, listen to me carefully.
It's not what you think.
What do you think I'm thinking?
What did you do?
Hurry up and tell me!
Gosh, I can't believe this.
So this is the answer sheet before it was corrected,
and this is the answer that Ye Rin wrote today?
Yes.
They're identical.
We changed the numbers.
How did she solve the problem like this?
It's like she copied this answer sheet.
No, I'm not saying she did.
No way.
You don't think someone leaked the answer sheet, do you?
Ye Rin, what is the matter with you?
What should we do?
But what if it was really a mistake?
Is that completely impossible?
We might be able to find out by looking at the test papers.
Students use the blank space to solve the math problems.
If she made a mistake, we should be able to find it.
You're right.
Then let's ask her to bring the test papers...
after the midterm exams are over.
After they're over?
We should let her finish her exams.
If we raise an issue right now,
she might blame us and say we made her get bad grades.
It'll only give us a huge headache.
I see.
(Asung High School)
Darn it.
I'm extremely sorry.
I understand...
if you choose to expel Ye Rin and have my wife reported.
They say, "Preparing for university is like entering a fiery pit."
I really love that saying.
I want Asung Empire to become a fiery pit...
with blazing flames and burning lives.
Then there's a sharp blade that gets created...
after it was forged many times inside the hot, burning fire.
What's the point of living in paradise where everyone is happy?
A true winner is a person who survives the fiery pit.
I wanted Ye Rin to do everything she could...
to survive the fiery pit...
and become a sword I could wield.
For that to happen,
she should not have gotten caught.
You knew all about...
In Asung High,
do you think there can be anything I do not know?
The math answer sheet?
Ye Rin's mother asked for it.
But I refused, of course.
Give it to her.
Pardon?
Give her the answer sheet.
Ms. Noh.
However,
I know nothing of this.
Now and even in the future.
Please forgive her.
Please forgive Ye Rin just this once.
What if I do?
On Ye Rin's name... No, on my life,
I will not disappoint you.
I swear.
- Darn it. - No way.
- Okay! - My gosh.
All my grades went up!
How do you do better and better?
- My grades are up. - That's crazy.
- Full marks? - No.
- Let's have a look. - Is that the old one?
Hang on.
- Baek Seung Yoo's insane. - Why?
No way. Full marks in every subject?
- That is really insane. - Full marks?
My mom will kill me.
- Darn him. - Hey.
This is crazy.
How is this possible?
It's all about the ankle.
If your ankles are strong, you can kick the ball...
- Hey. - Janet.
- Janet. - Seung Yoo's here.
Baek Seung Yoo!
Full marks in everything.
In everything? Is that for real?
- Hey. - He's crazy.
Hey, what's this?
- What is it? - What is it?
What is it?
That's Ms. Ji.
- Where is this from? - Who took this?
What is it doing here? Who put it here?
I don't know.
What if I find a math problem that's worth all of this damage?
Don't look for it.
- What are you doing? - Is it yours?
Where are you going?
There are math problems you can't help...
but want to solve them and fall in love with them.
The problem will find you...
when you become strong and stable enough that you will not get hurt...
while trying to solve it.
I believe that one day,
you will achieve that.
I appreciate your present,
but I cannot accept this.
This is on the house.
My Seung Yoo did well in the midterm exams,
so I'm giving these out.
- Thank you. - Enjoy it.
This is on me.
I don't think you should be handing stuff out.
Why not? Is something wrong?
Seung Yoo...
- got full marks in everything? - Yes.
I heard he was the only one to get full marks in math.
Was Ms. Ji his special tutor or something?
- A special tutor? - I've heard strange rumors.
- Don't. - Why not?
How can the last kid in his year suddenly become first?
Something's definitely up.
My Gyu Yeong told me that...
there's something between Seung Yoo and Ms. Ji.
To use the kids' slang, it looks like they're flirting.
This is crazy!
Jang Gyu Yeong!
- Where are you? - Ma'am.
Hee Seung!
Where's your son?
- What is this about? - "What is this about?"
Why? Are you afraid I'll hurt your son?
Then you shouldn't have gone and talked about mine.
Well, that was just...
a rumor among the kids.
Okay. A rumor?
Tell Gyu Yeong to come here and repeat those rumors.
Listen carefully.
Your son Seung Yoo.
He's busy throwing himself at and confessing his love to Ms. Ji.
Gyu Yeong saw him at it, okay?
- Gyu Yeong saw him? - Yes.
What did he see?
I bet he just hallucinated because he's angry...
he's no longer the best at math.
- What are you saying? - What?
My son beat yours,
and now your son's math scores went way down.
He should blame his lack of smarts,
not my son.
Are you out of your mind?
Yes, I am! So what?
Delete your message about them flirting.
If you don't, I'll sue you for slander.
And tell Gyu Yeong to watch what he says, okay?
Or I will rip his cheeks open.
If you ruin my garden,
do so at the risk of getting yours ruined too.
Oh, no! Oh, my gosh!
My gosh.
Those darn women...
will say just anything.
Just because they can.
I'm home.
Seung Yoo.
It's not like that, is it?
About you and Ms. Ji.
It's just gossip, isn't it?
What do you mean?
The moms keep saying nonsense...
that you professed your love for her and whatnot.
Is it true?
What's going on? Talk to me!
It's not like that.
Yes, it had better not be.
What if your dad were to find out?
Be careful.
Everyone's wary of you because your grades shot up.
Okay?
Ms. Ji...
is getting married soon.
Oh, that's great news.
We should congratulate her.
Let's go to the wedding. When is it?
It's this Saturday.
I can't go.
Why not?
- Hello. - Hello.
(The schedule is as follows.)
(Note: Asung High School junior Baek Seung Yoo will present.)
Ms. Ji.
Can we talk?
It's about Ye Rin.
I thought we should tell those in charge.
So I told the vice principal just now.
I see. What did he say?
That we don't have to check Ye Rin's papers.
He said we'll soon find out what that means.
What does that mean?
I'm not exactly sure,
but they called an Academic Performance Management Committee.
I'm sure it'll come up then.
An Academic Performance Management Committee?
You get married tomorrow.
Don't worry too much about it right before your big day.
(2017 Academic Performance Management Committee)
First of all, I want to say I'm sorry.
Listen carefully to what I say.
Okay.
I will make it so it never happened.
Nothing...
happened.
I have something to tell you about the junior year...
midterm math exam.
(Principal Oh Jin Taek)
Yes, it's me.
Can we talk for a bit?
There's a problem with the math exam?
Tell me more.
- Your old number? - Yes.
- Text me later. - Get going.
It's English?
Ye Rin.
Can you bring your math exam to the counseling room?
- What for? - I want to check something.
I threw it away.
You threw out your exam questions?
Ms. Ji.
I think we're in trouble.
Just a moment.
Let's talk about it later.
What is it?
They'll have the kids retake math. The whole exam.
It'll take ages to compile the questions.
There will be another exam? Why?
- They'll retake the exam? - If that happens,
the existing scores become void...
and won't be a problem.
That's true.
You're right. I'm impressed.
I was down on my knees right now.
Do you see it?
You don't, do you? What a pity.
Like I said, this is the last time.
You bet it is.
From now on, you just have to watch...
how Sung Min Jun keeps his word.
Look forward to it.
- A retake? - No way.
- Can we not? - That blows.
Be quiet!
Why must we retake the exam?
One of the questions required a solution...
that isn't covered in your textbooks.
We're organizing a retake to keep things fair, so it's final.
Which question was the problem?
- Number 15. - Number 15?
Now look.
You solved it with L'Hopitals theorem, didn't you?
- Yes. - Yes.
I guarantee you that everyone solved it this way.
It's such a simple and useful theorem...
that it's mentioned in class,
but not mentioned in your textbooks.
Because it's not in your textbooks,
it should not be in any exam.
What if I guessed and got it right?
The probability...
I didn't solve it with L'Hopitals theorem.
What? Who said what just now?
I didn't solve it that way.
What a nuisance.
So what if you didn't solve it this way?
Did you use Taylor's series?
Seung Yoo got full marks in math this time.
If he solved it without using L'Hopitals theorem,
isn't there no problem, then?
- Yes. - Yes.
- Can't we skip it? - Let him show us.
Silence!
How dare you interrupt a teacher?
Also, Baek Seung Yoo got full marks. So what about it?
You have to resit an exam you got full marks on,
and you're ticked off?
Do you think it's all about getting good grades?
You must be a decent person first.
But then, what did you do wrong?
It's the teacher's fault for egging you on,
saying you're good.
Look at you.
Look down.
Look down!
See me after class.
It can't be solved without L'Hopitals theorem.
This is insane. I came up with this question.
I just took it for granted they could use L'Hopitals theorem.
We don't have to check Ye Rin's papers.
He said we'll soon find out what that means.
Do you still think you're a math genius?
Don't you?
I've seen many kids like you.
Kids like you who show off never last long.
Because someone coddles you for having talent,
you think you're special, don't you?
You were a child wonder once, but that faded right away.
How dare you? I'm still talking!
The limit value is guaranteed as K,
so if you substitute the X from Tangent X to EX...
and use addition...
You can get the value of K...
without using L'Hopitals theorem.
Baek Seung Yoo. Can I give you a hug?
Thank you so much. You saved my life.
That's a weight off my chest.
We don't have to do a retake, do we?
I'll buy you something tasty.
(Teachers' Office)
Seung Yoo.
Thank you.
Thanks to you, many students didn't have to suffer unfairly.
"Suffer unfairly"?
You don't need to know.
What happens at school that are sometimes nonsensical,
I will try to take care of.
Is something wrong?
Good luck tomorrow with your presentation.
You'll do just fine.
(Counseling Room)
Hi, Ye Rin.
Ms. Ji wants to talk to me.
What for? You're retaking math anyway.
I don't know. What should I do?
Try and stall. I'll come over.
(2017 Second Semester Midterm Exam)
Is there anything you have to tell me?
- Ms. Ji. - Go on.
I heard we have to resit math.
This score won't mean anything.
Why must we talk about it?
There won't be...
another exam.
There won't be another exam and this score of yours will stand.
So we must talk about it.
- You can't organize a resit? - I apologize.
Baek Seung Yoo made an objection.
What do you mean?
He solved the problem in a way we never imagined.
I'd never seen anyone solve that problem like that.
How were you able to write down the solution...
from the answer sheet before it was amended?
Ye Rin.
I don't know what you're talking about.
- You really don't know? - I don't.
You have to know.
You have to have something to tell me.
You must.
I truly hope you have something to tell me.
I'll ask you one last time.
Do you have nothing to say?
Ye Rin.
- I need help. - What's wrong?
- She needs to see the nurse. - I'll carry her.
- Wake up. - Isn't that Ye Rin?
I think it is.
- What happened? - That was Ye Rin.
Ye Rin.
- I think it's hyperventilation. - Okay.
Ye Rin.
- Ye Rin. - Excuse me, ma'am.
- Ye Rin. - Stay calm.
- You can't do this. - Go away!
You... What are you doing?
- Let go, Seung Yoo. - Let go of me.
Let go!
Baek Seung Yoo!
Let go right now.
Let go!
You must be out of your mind.
I heard there was something going on between you two.
I bet you feel reassured thanks to him.
Ms. Yu.
What do you think you're doing?
Is it true?
Did you really hit a teacher?
Apologize to Ms. Ji right now.
No, that's not what happened.
Or...
would you like to go to the police station?
I must've been out of my mind.
I'm sorry, Ms. Ji.
I wasn't thinking straight...
because Ye Rin had collapsed.
Please forgive me.
I heard...
that you raised questions about the mistake...
that Ye Rin made on the math test.
- But... - Ms. Yu.
Please wait outside.
What?
I said, wait outside.
What did you mean by what you said earlier?
Oh, about you and Seung Yoo?
Did you not know?
- That's... - I think you should...
talk to me first.
Forget it.
No, stop.
- Are you okay? - Hey, about...
what Ye Rin's mother said earlier...
About you and Ms. Ji. It's not...
- I meant to say it can't be true. - It's not true.
- It can't be true. - It's not true.
- It's absurd. - Yes, it's absurd.
Imagine how dumbfounded Ms. Ji must be right now.
- Exactly. - She's getting married tomorrow.
This is so upsetting.
The juniors won't be taking a retest for their math exam.
Yes, I heard.
As much as the test results are valid,
there should be a thorough investigation...
to ensure that the scores are given out fairly.
Okay.
We'll check if the test questions were made and checked properly...
and if the original copy and answer sheet...
were signed and kept confidential before the actual test.
We'll carry out an overall investigation...
and have a talk with the student and parents in question.
I'll make sure to give you a report...
regarding the entire process.
I'll be waiting for the results.
Nothing's changed.
Gosh, I can't believe it.
Did you guys hear?
Hello?
Yoon Su, congratulations on getting married.
Yoon Su, you should join us.
Stop it.
Did you get off work?
I'm on my way home. Are you still outside?
Yes, these guys won't let me go.
Would you like to drop by?
No, I'll be resting at home.
We need to wake up early tomorrow.
Okay, go ahead. I'll drop by after I'm done.
Okay. Don't drink too much.
Are you Ms. Ji Yoon Su?
Welcome.
What do you need?
Have a seat. Let's drink wine.
We met at the competition last time,
but we only got to say hello.
You haven't changed at all.
Why am I the only one aging?
Why did you want to see me?
I heard you have something to say.
Isn't it hard to work as a teacher at Asung High School?
Do you remember Mr. Kim Jung Yoon?
He used to be our teacher at Asung High School.
(Seoul Education Office)
Mr. Kim.
Let's go.
Why didn't you come?
We promised to testify to the inspectors.
But why didn't you show up?
It's our fault.
Because of us, Mr. Kim...
It wasn't our fault.
He brought it upon himself.
Don't you get it?
Our school doesn't need good teachers.
The ones who remain end up becoming the ones...
that the school needs.
It didn't matter what kind of person Mr. Kim was.
To my dad,
he was just a whistle-blower that needed to be gone.
After that day,
I could never look at you properly.
I don't get why we're talking about this right now.
I don't want you to go through the same thing.
The current Asung High School. Director Noh Jung Ah.
She's even worse than my dad.
What's your point?
Let me know whenever you need my help.
Of course, that is, if you trust me.
Are you any different?
I'm asking because I'm curious.
I want to be different.
Fine. I get what you mean.
I'll see you next time.
(Vice Principal Choi Sung Han)
We have a situation.
Ms. Ji just met Principal Noh Yeon Woo.
Honey, I'm back.
Hey, you're back.
Take a look at this.
Here.
What do you think? It's perfect for the presentation, right?
Does it fit? Did he try it on?
Not yet. I told him to come over.
If it doesn't fit, I'll exchange it.
Ms. Ji.
Why are you here this late?
I came to give you something.
I wasn't able to wrap it.
Tell Seung Yoo...
I wish him luck with tomorrow's presentation.
It looks nice, but it looks old.
"Math JHW"?
- Give that to me. - Why?
I'll give it to Seung Yoo.
Wait. There's a name on it.
- You're home. - Seung Yoo, take a look at this.
Ms. Ji left it for you.
She wished you luck tomorrow.
She said your presentation...
has something to do with that pen.
(Math JHW)
When was she here?
Ms. Ji.
Seung Yoo.
Congratulations...
on your wedding.
Thank you.
I'll root for you too.
You will do great, Seung Yoo.
You're wearing 1729 again.
Do you like math?
I'm Ji Yoon Su, a junior math teacher at Asung High School.
Baek Seung Yoo, not Baek Min Jae.
I'm glad we met.

The wedding of groom Ryu Sung Jae...
and bride Ji Yoon Su will begin shortly.
Can the guests please enter the hall...
and take their seats?
Not long ago, someone posted...
an interesting paper on a lemma...
of a random cross-section of a convex body...
onto our website.
It's hard to believe, but it was written by a high-school student.
Let me introduce Baek Seung Yoo.
Please welcome the bride and groom!
There is a potential for error.
What's that?
- Is that her? - What is that?
- Who's that? - That's Baek Seung Yoo!
It's Baek Seung Yoo?
Congratulations...
on your wedding.
Things feel different today here at our studio.
We're very excited and thrilled.
It's probably because of today's guest.
Yes, that's right. He has an amazing career.
He got into MIT at the age of ten.
He passed the GED at the age of 18...
and entered Hanguk University with the highest score.
He won the 2020 Henri Poincare Prize, EMS Prize,
Ramanujan Prize, and many other prizes in the field of mathematics.
And now, tell us about his achievement...
at the 2021 International Mathematician Olympics.
At the 2021 International Mathematician Olympics...
that was held in St. Petersburg, he became the first Korean...
and the youngest person ever to win the Lucipel Prize,
which is as prestigious as a Nobel Prize in mathematics.
Please welcome...
Mr. Baek Seung Yoo.
(Melancholia)
About what you asked me to look into last time...
I still haven't heard anything.
Noh Jung Ah wants to see you soon. Did you agree to meet her?
There's no point in getting involved.
Do you really think Seung Yoo doesn't know?
Hello, I'm Baek Seung Yoo.
There has to be an ulterior motive.
Otherwise, why would he choose to work there of all places?
I need you to look into something for me.
This question is from someone with the nickname "Calculus".
I waited for the right moment.
Instead of trying to find the answer,
I waited for the answer to come to me.
