(All characters, places, institutions, incidents,)
(and organizations portrayed in this drama are fictitious.)
I'd like to check the CCTV footage inside the school library...
from around 4:20pm to 6:30pm on September 14.
Just a second.
It's me, Yoon Su.
Can we meet right now?
Yoon Su.
It's been a long time.
Have you been well?
Did you follow me here?
Yes. Kind of. I'm sorry.
I must've startled you.
Can we talk?
I have nothing to say to you.
I do.
Yoon Su, wait.
I...
She says she has nothing to say to you.
You came here to see him?
Were you in touch?
Since when? Recently?
Or all along?
What are you doing?
- Go inside. - You go inside.
- What is it you have to say? - I wonder.
I don't even remember what I came here to say.
What are you thinking?
- Why are you and him... - Must I...
explain that?
Must I explain, then?
What your life became because of that punk?
What's wrong with my life?
Whatever the case, it's none of your business now.
I don't know how you found me.
But stop following me.
Don't do any background checks on me either.
How do you...
not know any shame?
I haven't seen you in four years and this what you're like?
I don't believe it.
You won't even explain?
It isn't any of my business now.
But still, you'd better act with caution.
If you had from the start, this would never have happened.
- Are you all right? - Si An.
I saw her live presentation.
How will the school handle it?
We haven't decided yet.
Both students say the other copied their work.
We're looking into that.
Do you know when she borrowed Ji Na's laptop?
The 14th, Tuesday.
She showed me her first draft the day before.
I'll make sure she isn't wronged.
Don't worry too much.
How?
Do you have a plan?
If you don't, I'll sort it out my way.
"Your way"?
Don't tell Si An we met.
You can't even tell me...
what you're thinking and what you'll do?
Let me.
Don't you trust me?
Why should I trust you?
My gosh.
What are you doing, Ji Na?
- Where do I stab it? - What?
You said you stabbed if you were annoyed.
I want to do that too.
You're crazy.
- Are you afraid of me. - Yes. I am.
You shouldn't be.
You should be grateful.
Others look down on you because you're not competition.
But I at least considered you competition.
Aren't you grateful?
Remember your place.
Are you sure you're maintaining...
the honor and dignity of this school?
- What? - I didn't steal anything.
I didn't steal the watch or the assignment.
Hello, sir.
An orientation?
Yes, she'd like to meet first.
The thing is, the tutor made a rare request...
to meet you in person.
- I would like that. - How about lunch tomorrow?
Let's meet at 12 noon.
I'll text you a decent location.
I will think positively of the offer you made before.
Then we should meet as well in the near future.
I'll be in touch.
Tomorrow noon, Principal Noh Jung Ah.
Come to this location.
Must I explain, then?
What your life became because of that punk?
Unlike Yoon Su,
you were protected from the aftermath...
not because you were good at math.
It was because you were a minor at the time.
If you go any further, you can make no excuse.
Are you saying that for my sake?
No.
It's a warning.
Stay out of Yoon Su's life.
Please, don't come around again.
What right do you have?
You did nothing when you did,
and now you have no right.
Also,
you can say whatever you want to me,
but don't talk to her like that.
What?
Aren't we in the same shoes?
Back then and now too,
you're nothing to her.
Like you said, I was a minor then, but not anymore.
(Myun Yeok Gong Bang)
It's nice and hot in here.
Ye Rin, your skin is so rough.
Let out some sweat and detox, okay?
This is nice.
- Let me see. - No.
Mom, wait here for a bit.
What? Okay. Don't say I'm here.
Bring your head forward.
- My face looks bigger. - It doesn't.
So Jung, Hyung Do.
My gosh.
Hi, Ye Rin.
What's going on here? Are you...
You're right. We are more than friends.
Ye Rin. Can you keep it a secret for a while?
Yes, please. So Jung isn't ready yet.
- I'm embarrassed. - Okay.
I moved. Who's coming to the housewarming?
Gyu Yeong moved out.
He's having a housewarming.
- Should we go? - Of course.
You'll go too, right?
- Should I invite Seung Yoo? - Yes.
- Should I? - Yes.
You have a new number, right?
Put it in.
See you around.
Ye Rin, you'll go too, right? Let's go.
Okay, I'll go.
Hello. I'll show you to your room.
(Director...)
This way.
Sorry, I'm late.
Are you by yourself?
Yes, I just got a call.
Something unavoidable came up.
Choi Si An?
The clinic instructor is her supporter?
Yes.
I heard something unfortunate occurred yesterday.
She was very upset after hearing what happened.
What a coincidence.
We're investigating the matter.
Why don't you resolve it amicably?
If you take good care of Si An,
I'm sure our instructor would cherish Ji Na as much as Si An.
Shall we discuss business since it's just us anyway?
(Future Dream Orphanage)
Ms. Ji.
I brought some snacks.
Again? Thank you.
This is great.
Good timing.
I hope they like it.
Mr. Paik.
What are you doing here?
Why are you here?
Mr. Paik brought us a bunch of math tools.
He's teaching us math while he's here too.
Kids, snack time.
- Yes! - Enjoy.
I'm donating my talent, as you can see.
Did you get home safely yesterday?
Si An, I'm going to go.
Already?
Be right back.
Why are you leaving?
Are you uncomfortable because of me?
Yes, I am.
Let me make myself clear.
Live your life.
Stay out of mine and stop lingering around me.
When I hid from the world...
and couldn't be honest with myself,
you got me out of that rut.
I want to do the same.
That's right. I have something for you. Hold on.
I planned to give it to you the next time I saw you.
Don't your feet hurt from wearing such high heels?
You used to wear comfortable shoes before.
Get back safely.
- Save some for me! - Okay!
- Don't eat it all! - Hurry up!

Hi, honey. I'm about to go to the center.
Don't worry.
Bye.
(No memory card)
Min Jun.
You really are having an affair.
A math museum?
You can proceed in Seung Yoo's name, correct?
Sure.
We'll have our work cut out for us.
I'll make it a landmark in my education business.
A national math museum.
You're on another level entirely.
I'll talk to Minister Shin about it.
Isn't Ryu Sung Jae his aide?
Yes. I see him now and then.
He comes golfing with the minister.
- Is he married? - Not yet.
Is he still not over Ji Yoon Su?
That's silly. It has been four years already.
Hold on. While we're on the topic.
Can we get a tee time at Western KFCC?
- With whom? - Minister Shin.
And Assemblyman Sung Min Jun.
Okay. I'll check.
Okay.
These are the desired colleges and majors...
for the Global Talent Class students.
Prepare a networking event with their admissions officers.
I need to talk to you about something first.
- Go ahead. - Ever since the ivy league scandal,
everyone is being cautious,
so networking is tough.
The commission will be very high.
Don't worry about the cost.
Money is one thing.
The problem is the method.
We'll have to be discreet.
I'll tell you the method now.
Just do as I say.
First, establish a foundation.
One that helps talented but poor students.
A nonprofit.
A scholarship foundation?
I'll get the approval from the Ministry of Education.
All you have to do is prepare the documents.
The foundation is for laundering bribe money.
Parents donate to the foundation.
This money is sent to admissions officers abroad...
in the form of donations.
- Hello. - Hi.
Mr. Paik.
The principal would like to see you.
I was just about to...
No.
Alone.
I see.
It's about the public class, right?
Do you know what they're going to do?
The principal will take care of it. Don't worry about it.
Mr. Paik is a teacher in our math department.
How could I not worry about it?
If you're so concerned,
you should take care of things in advance...
so these things don't happen again.
Was it my fault? Did I mess up?
Hello? Asung Academy of Mathematics and Arts.
Pardon?
Ji Na...
actually admitted that it was her and told me she regretted it.
As her mother, I'd like to tell you that I'm extremely sorry.
I think she was overly excited about joining your project...
and ended up crossing the line.
This project isn't going to be reflected in her grades,
so could you forgive her just this once?
Ji Na will no longer be able to take part in the project.
This may be a school project, but it's also my thesis paper.
I have full authority to choose the participants.
Or...
I could just proceed with the math museum project...
individually without having the kids or the school involved.
I was thoughtless.
You do have full authority.
Instead,
let me make up for this by giving you my full support.
You know the promotion committee for the museum...
is being set up this week, right?
- Yes. - I'll look forward to it.
We have a situation.
I just got a call from the Office of Education.
- The Office of Education? - Yes.
I think they called because of this.

(Jung Ah)
- Hello? - Hey, what's your problem?
It wasn't me. Think about it.
Why would I ask Cho Yoon Ah again? It'd be obvious that it was me.
- Then who did this? - Are you seriously asking me?
(Assemblyman Sung Min Jun)
- Hello? - I read the article.
I just talked to someone from the Office of Education.
What did they say?
There's going to be an audit.
I want to know the names of everyone on the audit team...
and how big of an investigation it's going to be.
- Pass! - Come on!
- You asked to see me? - Have a seat.
Ji Na admitted that she copied your presentation...
- and agreed to leave the team. - Really?
How?
You don't need to know.
Mr. Paik.
Thank you for taking my side.
I never took your side.
I checked the facts and punished the person who was responsible.
Still, I felt reassured to know that you believed me.
- Keep going! - Go!
Si An gets to stay, and you were asked to leave?
Did you really copy her homework?
Si An is so annoying.
Get out of my way.
What's your relationship with Paik Seung Yoo?
Why does he always take your side?
It's Mr. Paik, not Paik Seung Yoo.
Do you have no respect or manners?
Who do you think you are to lecture me?
- Ouch. Hey. - My gosh.
Stop it.
Hey.
I know you guys don't like me,
but I never caused you guys any harm,
and unlike you, I never once stole anything.
Now you know what happens if you mess with me.
You'd better watch out from now on.
We were informed that some of the applicants...
of Asung Academy of Mathematics and Arts...
were asked remarkably easy questions...
during the interviews they had prior to entering the school.
An audit?
This is so unexpected.
Everyone's going to be sensitive for a while.
We'll be asked to hand in tons of files and paperwork.
Those who were in charge of the admission are going to be busy.
They'll be busy getting investigated.
It's going to be a mess.
Mr. Han, weren't you also in charge of the admission?
- What about that? - Well...
I was just going to say that you're going to be busy.
You're the ones ruining the school atmosphere...
by gathering around and gossiping like that.
Don't let the audit disturb you...
and just carry on with your work as usual.
As usual!
Goodness.
The Office of Education will be auditing the school.
The students called into question turned out to be children...
of high-ranking politicians and renowned businessmen.
What happened?
I took care of the issue with Si An.
Principal Noh admitted everything without a big fight.
What did you do?
That's what I should be asking you.
Are you trying to become a whistle-blower?
I'm going to disclose everything one by one.
Then we'll eventually find out what happened four years ago.
We'll find out who did what.
Do you really think you'll be able to uncover everything?
If it were that easy, why do you think I failed to do it?
Then tell me what you're planning to do.
Tell me. You're making me nervous.
I'm going to reveal everything.
Not about what happened in the past but about what's happening now.
I'm going to repay them by doing exactly what they did to me.
Let's do it together.
I told you to forget what happened and just live your life.
How can I forget?
I could never forget.
I couldn't help but feel like a fool.
"Why couldn't I do anything? Why couldn't I protect her?"
Just leave it to me.
I'll deal with the people who need to be dealt with.
I won't be doing anything with you.
Your return was never part of my plan.
It will only cause an error.
- Welcome... - Welcome...
Didn't we tell you that you're not welcome here?
I didn't want to come either,
but my son wanted your macaroons...
with all due respect.
- How many? - I'd like 12,
Ms. Min.
I heard Mr. Paik was...
going to build a museum.
- A museum? - What kind of museum?
The National Museum of Mathematics.
- Did you see him? - What?
- I mean, my son. - Yes, I did.
He was very handsome and all grown up.
Thank you.
- Mr. Paik Min Sik? - That's me.
Here you go.
(To Mr. Paik Min Sik)
(Asung Academy of Mathematics and Arts)
"Asung Academy of Mathematics and Arts"?
What is it?
Honey, Seung Yoo...
What about Seung Yoo?
He sent his thesis.
Look.
Hello, Dad.
No.
Okay, I won't play.
Shall we get some air?
Dad.
I heard you enjoyed playing against Si An.
And that you chat a lot with Seung Yoo.
Why not with me?
Is it because I resent you?
I did. I did resent you a lot.
When I graduated from middle school and high school,
and even when I got into university,
you were never there.
You were always at home.
You concentrated on your proofs.
Even when Mom died.
I'm sorry. I talked without thinking.
I don't resent you anymore.
You still solve problems every day.
You must enjoy it.
What...
will you prove?
What is your proof?
Dad, I...
I don't solve math problems anymore.
Problems that I used to like,
the ones with no answer.
Now, whatever problem I see, my heart doesn't beat fast.
I don't enjoy it,
and I don't want to solve it.
I'm...
no longer a mathematician.
Such a time comes.
Whatever problem you see,
your heart does not respond.
You don't feel joy,
or the yearning to solve it.
That time.
Every mathematician goes through that period.
A mathematician who doesn't go through that...
cannot solve the next problem.
Jang Gyu Yeong's housewarming. Do you want in?
(Lee Hyun Jae)
(Ms. Ji Yoon Su)
How cute.
- You're always cute? - I am not.
- Who is that yellow monkey? - Will you stop it?
Go away.
I'll show you photos from the sauna.
- Do you need help? - Everything's done?
You are no longer my friend.
I'm free at last. Great. Thank you.
- Show me a few more. - Look.
You two look more alike.
Get a girlfriend if you're jealous.
Here's the food.
Hey. Let's take a photo.
Me and you? No way. People will get the wrong idea.
The wrong idea? Who can't get the wrong idea?
It's Seung Yoo.
Why is he so late?
Get in here quick.
Now we can eat.
- Hey. - Hi.
Sit down.
How long has it been?
- About 30 days? - About that, yes.
What do you like about each other?
You emptied both bottles already?
Are you okay? Are you drunk?
- No. - Who am I?
I'll get more from the convenience store.
Do you need anything else?
- You'll go with her? - Why not?
Wine. And ice cream.
Okay. Go on eating.
- See you. - Don't take too long.
I hope you hurry.
Give me that.
Let's sit for a while.
Do you feel awkward around me?
What?
I'd like us to get along.
What do you mean by that?
I'd like us to be closer.
And forget about the past.
"The past"?
The Jeju airport photo.
You took it, didn't you?
You were at the conference too.
Then why...
Why do you want us to get along?
Don't you hate me?
You liked Ms. Ji back then,
and because of my photo...
You must've had your reasons.
I don't think you'd have done that for no reason.
Back then...
Actually...
Why are you crying?
Let's go inside.
Do you have feelings for her?
Does it matter to you?
To me?
No.
You aren't coming?
You go ahead. I need to make a call.
I came for Gyu Yeong's housewarming.
He just moved here.
Why are you doing this?
Because you don't want to see them?
I don't care about that.
I just don't want to be found out...
and have my plan ruined.
- What about you? - How do you do this?
- Hey. - It's from Ye Rin and Seung Yoo.
- They brought it? - Really?
Where's my cool friend Seung Yoo?
He was going to make a call.
Why did you come by yourself?
Whom was Seung Yoo with just now?
What? I didn't see anyone.
Is something going on between you and Seung Yoo?
Nothing much.
You were crying.
Why did you cry over nothing?
What's it to you?
That's right. Gyu Yeong.
Didn't you say you saw Ms. Ji Yoon Su?
You did? Where?
Sorry.
My cool friend Seung Yoo is here.
Let's eat.
Hey, you don't have a girlfriend, right?
Want me to set you up?
There are girls lined up asking to meet you.
Me too.
Hold on. Me first.
What do you say? Want to meet them?
I like someone.
Oh my gosh. Since when?
Without telling us? Who?
Someone.
Someone whom I like more after being reunited after so long.
- Wow. - What?
Does that mean...
it's someone we know?
It's someone that you saw again after a long break, right?
Is it...
Is it me?
- Hey. - Probably not, right?
- No way. - I know.
Just kidding. I'm trying to be funny.
- You punk. - I know.
(Paik Seung Yoo)
Protrude.
Protrude...
- Gosh. - Protrude.
You look like you were the one who wrote it.
Does it make sense to you if you study?
I can't understand any of it.
And...
Among the auditors coming,
Shim Sang Wook will be the easiest to talk to.
I hear he loves this wine.
I'll relay it to him.
I have the documents.
I'll take care of the originals.
Good job.
Give them everything they ask for and cooperate with them.
I will.
- Thank you. - Thank you.
How's the approval...
for establishing the foundation coming along?
Well... You'll get it soon.
Tell them to prepare a scholarship grant ceremony.
I've chosen an appropriate student.
But aren't you doing too much?
The museum project is huge as well.
Assemblyman.
You need to think big.
You're striving to become the party leader soon...
and even the president.
You should go.
Let's open a bottle of this wine too after the audit.
Oh my goodness. Noh Jung Ah and Assemblyman Sung Min Jun?
What are they doing?
Oh my gosh. What's going on here?
Hello, director.
Kim Ji Na's orientation is at 6pm tonight.
I'll make sure she isn't late.
Also, we should get the approval soon...
thanks to the documents you prepared.
That's great news.
You must be busy with the audit and everything.
Don't worry about that. It's nothing.
Yes.
Bye now.
Send in Choi Si An.
I haven't had this in ages.
Tteokbokki equals love.
Your mom won't let you eat this, saying you'll gain weight, right?
Eat up.
How are things at school?
Not good. Because of the audit and whatnot.
They pretend it's fine, but the tension is high.
I see.
Orientation is at 6pm. Don't be late.
I have to go.
Can you drop me off at my academy?
- Thank you. - Good luck.
Thanks.
I've been meaning to meet with you,
but I got busy with this and that.
Me? Why?
I want to give you a scholarship certificate.
You'll receive money for educational costs.
I know you're getting some now. This will be in addition.
Out of nowhere?
How long have you been going to the math clinic?
How do you know the instructor?
What do you mean?
It's an academy that's hard to get into,
and an instructor who's impossible to meet even with a pile of cash.
I wonder how the likes of you ended up there.
You don't have a strange relationship, do you?
She's a woman.
A woman and single.
She probably cares for you like her child because she has none.
I'll go if you're done.
She makes an insane amount of money but has no time to spend it.
Her heart feels empty...
and probably wants to fill the void by taking care of you.
Do you know something?
Kids like you are a dime a dozen.
So?
You may be dumped at any time,
so don't trust her too much or get too arrogant.
You have to leave all of your personal items here.
You can only take this pen and notepad with you.
- Why? - Because taking videos,
pictures, and recording lessons are prohibited.
Here's a confidentiality agreement.
Read it carefully and sign it.
Your instructor will be here soon.
They're mad tough.
(I will not share information regarding any instructors.)
Hi.
You're prettier in person.
I saw an amusing video,
and you were in it.
A video?
How did you...
Do you go to the same meditation center?
Why are you doing this to me?
What do you want?
Why would you ask me that?
Does it look like I'm trying to blackmail you?
Then why are you doing this?
Don't be scared.
I'm not a scary person.
I just want to know...
why a pretty girl who's no different from her peers...
would do something like this.
Why don't you tell me what's deep down in your heart?
Instead, I'll keep this a secret forever.
Even from my mom?
Of course.
Everything's ready.
What should I do with the original copy?
Get rid of it all.
Okay, I will.
(The Seoul Metropolitan Office of Education Will Audit...)
(Asung Academy of Mathematics and Arts for Admission Irregularities)
Are you busy?
- No, I'm free. - How was Kim Ji Na?
She's smart and quick to understand things.
She's softer than she looks, too.
She's Principal Noh's daughter,
so please take extra good care of her.
- Sure. - Can we have dinner together?
There's something I'd like to discuss.
Sure.
I'm going to keep an eye on Cho Yoon Ah.
I don't think the Office of Education...
would've decided to do an audit unless they knew something.
I have a bad feeling about Paik Seung Yoo.
Let's make good use of him...
and get rid of him once we're done.
You should head to the event.
Yes, I should. It's the first official event.
Are you really not coming?
I should be careful for now.
Then why don't you join us for dinner?
The minister will be there, too.
Sure. I'll see you later.
Let's do it on the count of three.
- Sure. - Okay.
Okay.
- One, two, three. - One, two, three.
(Establishment Ceremony of Promotion Committee...)
(for the National Museum of Mathematics)
Thank you.
We look forward to everything.
One, two, three.
- Good luck. - Good luck.
This way.
You become younger as years go by.
Goodness, you flatter me.
- I'm glad the ceremony went well. - Me too.
Give me a call if you need anything.
Thank you, sir.
I'm sure you've noticed, but there were a lot of reporters...
at the ceremony earlier today.
A lot of people are looking forward to the project...
Welcome.
The minister and the others have arrived.
Oh, okay.
The director you ate with last time...
is also here.
Director Lim?
Yes.
You're here.
Long time no see.
Have you been well?
I heard you were the head of the promotion committee.
Yes. I've got a lot on my shoulders.
The minister will be here soon.
Where's Mr. Paik?
What's this?
Principal Noh asked us to give you this dish...
once you got here.
She did? Thank you.
I came here with her last time.
I told her that I should also bring you here someday,
which is probably why she prepared this for us.
Let's eat.
By any chance, are you at Michaena?
Is Ye Rin doing well?
Oh, yes. She's busy studying these days.
Professor Kim, who teaches in the Computer Science Department,
graduated the same school as me.
- I'll give him a call and tell... - Thank you for this dish.
I'm actually here with the teacher from the clinic.
I told her that the dish was from you.
(By any chance, are you at Michaena?)
Yes.
Enjoy.
My goodness!
Are you okay?
I'm sorry.
I have plans to establish a scholarship foundation...
to help students who are talented but aren't financially stable.
It'll be a non-profit foundation.
- Can I take this call? - Sure.
- Hello? - Come out.
What?
Hurry.
What's...
Once things get established,
we'll be able to regain our old reputation.
Yes, I agree.
I'll make sure everything goes meticulously as planned...
What's going on?
I came here to eat with Principal Noh.
Assemblyman Sung is here too.
I don't know how she found out,
but she tried to enter your room.
Let's just stay like this for a bit.
(Melancholia)
I want you to apologize for everything.
That's Han Myung Jin, right?
What if he reveals everything that we did in the past?
Ms. Ji is back.
This is what you always do.
You get what you want...
by asking others to do your dirty job for you.
I try not to think about it, but I can't help myself.
I see when I don't want to.
Just because your life's a mess,
you can't ruin Seung Yoo's bright future too.
Once you say that, many things...
will change.
