Episode 1.

Everything in your life is a test. The more tests you take, the better you become.

School can't be that unjust. – Go Nam Soon

I feel like there's absolutely nothing I can do. – Jung In Jae

I wonder if I'll figure it out if I stick through with it. – Jung In Jae

Episode 2.

If you receive punishment for something you've done, you forget about it easily. But if you received it unfairly, you never forget it. – Jo Bong Soo

Whether you hate them or not, they are true students of yours only if you stick to them for quite a long time. – Jo Bong Soo

You get strength from knowledge. You need strength not to be treated unfairly. – Kang Se Chan

It's only pretty if you take a look at it closely. You have to look at it for a long time to realize that it's lovely. You too are like that. – Na Tae Joo (Wildflower)

Episode 3.

What you truly need right now is to setup specific goals for yourselves. – Kang Se Chan

What you need right now is a dream. Even though you can survive without being the best student in your class, if you don't have a dream you'll lack strength to endure things when they become uncertain and scary. – Jung In Jae

It's not time to let go of their hands just yet. – Jung In Jae

What is there to be happy about? If we have two homeroom teachers, it will be twice the nagging. – Gye Na Ri

I'll take charge of their grades and you can be in charge of nagging them. – Kang Se Chan

To be honest, I don't like going to school. I don't know why I go to school. When I go to school, I always get humiliated and a lot of annoying things happen. I'm not a good student, I don't have any dreams, and I hate getting beaten up. But the strange thing is, I always head to school automatically when I open my eyes in the morning. So if you're asking why I go to school, I only have one response: just because. – Go Nam Soon

Episode 4.

Se Chan: Does school take responsibility for the kids' lives?

In Jae: Even if we can't be responsible for their lives, at least it should be a place where they can lean on.

Should you leave or should I? We can't go together anyway, because every time I see you I want to beat you up. I prefer to have you go. You are good at running away. – Park Heung Soo

When I can't even mind my own business right, I end up caring too much about others. – Lee Kang Joo

I am not pretending to be strong. I really am strong. – Oh Jung Ho

If you only hold on to a student like that, do you think you won't hurt him? If you cover him up and wait for him no matter what he does, do you think you can film a happy ending later? If you're not going to take responsibility for him until the end, just quit now. That way, you won't be hurt too. – Kang Se Chan

It's not that you hate responsibility, you're scared of it right? – Jung In Jae

Because I can't take responsibility of it, I should not give him a hand either? – Jung In Jae

A mom who lost her child always says this. I only looked away for a moment and let the child's hand go for a moment, but the child disappeared. Even a mom sometimes lets go of her own child. – Kang Se Chan

Episode 5.

I'm sorry but I'm not giving up on you guys. So you guys can give up. – Jung In Jae

Heung Soo: What to do? You ended up using your fist again even though you retired it. Is it nice to be living a lie?

Nam Soon: This is me now.

Heung Soo: Really? Then I guess we're strangers.

Park Heung Soo really is your Achilles' heel, isn't he? – Oh Jung Ho

If I sit back and do nothing, someone will get hurt. But if I do something bad, nobody is going to get hurt. – Go Nam Soon

Episode 6.

Uhm Dae Woong: Once a troublemaker, always a troublemaker. That's what you call a habit.

Heung Soo: Continuing to suspect a student that you already suspected once, isn't that also a habit?

I can't forgive you for your intentions. – Jung In Jae

That's what school is about. As long as you remain as a teacher at a school, no matter how much you refuse the kids, they're going to attach themselves to you. But turning your back on them won't do anything, and you can't turn your back on them even if you try. – Jo Bong Soo

There's a limit to how much I can keep buried and let go. – Jung In Jae

I'm afraid of you more than anyone else in this world, you bastard. – Go Nam Soon

It's like he ran into a wolf while trying to escape a street dog. – Kim Jong Hyun

If I'm a gangster, then what does that make you? Will you please stop pretending to be nice and that you're sorry? – Park Heung Soo

Episode 7.

I don't have any desire for us to get along. You didn't expect me to accept that, did you? – Park Heung Soo

In life, the things that you don't see are more important than what you see. – Jo Bong Soo

He dreamed of being a soccer player. In order to play soccer, the coach told him to leave the gang. In order to leave the gang, he needed to get hit. After getting hit, he injured his legs. The gang leader is a jerk who stole his dream and that jerk is Go Nam Soon.

I'm scared I'm letting go of the final chance. – Jung In Jae

Nam Soon: I need to apologize and repay my debt to you.

Heung Soo: You should've apologized a long time ago. And debt... is this a debt you can repay?

I was just mad. I felt like he was leaving me alone and going far away. – Go Nam Soon

Nam Soon: Don't run away and get revenge on me.

Heung Soo: Revenge? What should I take away from you in order to get revenge? Do you have anything that's like soccer to me? If there is then try throwing it away. Try throwing away the most important thing to you, and then I will pretend to think that what you are doing now is sincere.

Heung Soo: It's school? Is this the most important thing in your life? This isn't good enough. Don't you have anything bigger?

Nam Soon: The thing I threw away right now, is it school? The thing I threw away right now isn't school; it's you, you jerk.

Episode 8.

Don't do something you'll regret later. – Kang Se Chan

A teacher who's indifferent is the worst teacher there is. – Jung In Jae

If you want to be treated like a highschooler, then use your head and use your heart a little bit too. – Song Ha Gyung

You left me behind a long time ago. It was over when you left me behind three years ago. – Park Heung Soo

A teacher can't teach the students everything. How are you going to persuade them to trust and follow you when you don't believe in it yourself? – Yoo Nan Hee

Episode 9.

I can't just stay out. If I don't know, I don't know. But if I do know, I can't leave it alone. – Park Heung Soo

Whether you're my friend or not, doing whatever you do, I'm going to stop you from doing something that will make you get jailed until the day I die. I don't know about other things, but I will keep this promise unconditionally. – Park Heung Soo

The teacher who teaches isn't important. The students who learn are more important. – Kang Se Chan

When you get out in the real world, there are many things that can't be solved with strength. – Jung In Jae

It won't get lighter, but if you try hard it becomes bearable. – Kang Se Chan

I thought if I change, everything will be fine. Even if it is late, if I get back to my senses, I thought I will be accepted anywhere. – Lee Ji Hoon

I keep thinking about what difference it will make if I keep living like this. – Lee Ji Hoon

Episode 10.

Heung Soo: Because it was a mistake, because it was your fault, does that change anything?

Nam Soon: Because nothing is going to change, because it won't change even if I try, I'm saying sorry. I'm sorry to death.

I was scared you would really leave me. I was scared you would say that you would never see a jerk like me again. I only had you back then. If you said something like that then, I would have no one to turn to. – Go Nam Soon

Asking a child to do what even adults find difficult to do on his own, isn't that just telling him not to do it? – Jung In Jae

She just doesn't know how to give up. – Kang Se Chan

I prepared myself for this but I feel incompetent. – Jung In Jae

How can all teachers in the world have the charisma I have? – Kang Se Chan

No matter how hard you try, we can't go back to the way we used to be. You and I can't pretend it never happened or forget about it. – Park Heung Soo

Jung Ho: Why do you care about my business?

Ji Hoon: What do you mean why? I'm your friend.

I can't pretend not to know and I can't pretend it never happened. – Go Nam Soon

No matter what, you should've stayed there before. Other than soccer, I only had you. When I wanted to die after I lost soccer, you should've been there. So I'm saying, didn't you miss me? – Park Heung Soo

There is no flower that would bloom without being shaken.

All the pretty flowers in this world bloom while being shaken.

While being shaken, it straightened its stem.

There is no love that would leave without being shaken.

Where is there a flower that would bloom without being whipped?

All the shining flowers in this world bloom while being whipped.

While being whipped by the wind and rain, the flower petals bloomed warmly.

There is no life that goes by without being whipped.

Episode 11.

Let's just let things go now, the incident. And let's just go our separate ways. It's not going to work out anyway. It's been over for a long time, you and me becoming friends again. You'll be sorry whenever you see me, and you being sorry will make me uncomfortable. – Park Heung Soo

In Jae: I feel like my sincerity was also rejected which makes me fall into low spirits.

Bong Soo: In order for sincerity to be felt, you need to know how to look into the children's sincerity.

Jung Ho: It's not that I hate school. The school hated me from the beginning.

In Jae: It's not that the school hated you, it just wanted you to change.

I'm not a victim. He's not an assailant. We're just friends, just really unlucky ones. And now we're in the process of making up. – Park Heung Soo

You are the teacher that I wanted to be. You are the teacher that I couldn't become, even though I sincerely wanted to. – Kang Se Chan

Episode 12.

Why are you asking me to do something you couldn't even do? You fell and you didn't get back up. So why are you asking me to get up and run again? – Jung In Jae

At a time like this, I really wish I didn't have a mom. – Kim Min Ki

Even if my body shatters, I'm going to send you out all bundled up. – Min Ki's Mother

Episode 13.

At least once in your life, there will be a moment when you want to die. It isn't wrong to think that you want to die, but it is a great thing to endure it and to overcome that desire to die. – Jung In Jae

I thought I was getting tied down because of you. But you know what? Honestly, I still miss you. – Kim Min Ki

It will be hard, but once you endure this everything will change. – Jung In Jae

All things will pass. It may seem like a big problem at the moment, but it will pass. Enduring and waiting for things to pass, that is strength. – Jung In Jae

I think this is the reality. Everyone tries and tries but many teachers won't become the teacher they originally wanted to be. – Jung In Jae

If you don't trust the teachers you face everyday, wouldn't it be too difficult to come to school? – Jung In Jae

Episode 14.

Whether it's your fault or not you need to straighten things out. – Park Heung Soo

Teachers who sincerely care about the students will remain and fill out that space. – Kang Se Chan

I'm not doing this for you. I'm doing this for myself. Well, whatever happens, I'm never going to stay in this school alone. – Kang Se Chan

Bong Soo: I think it's better to remain and see it to the end.

In Jae: Honestly, that's actually what I wanted to do but I wasn't sure whether I was qualified to do that.

They'll have no regard and step all over people like us. – Oh Jung Ho

I lived recklessly. I'd forgotten while I was hanging out with you. – Park Heung Soo

Episode 15.

During one's life, there's always an exception. – Kang Se Chan

At first it was hard, but as time went by I feel like it happened for the best. I came to my senses after that. When I think that I'm getting punished for all the wrong things I've done before, I feel like I deserve them. – Park Heung Soo

I was curious whether there were more like you out there. – Park Heung Soo

I wanted to put my heart to rest, you bastard. – Park Heung Soo

It's not better to do better than others, but it's more important to do better for yourself. Comparing yourself to others will only tire you out. – Jung In Jae

Whether she's hurt a lot or not, I think the fact that she's hurt is important. – Ha Gyung's Mother

If you don't stop yourself, no one will stop you. – Kang Se Chan

There was a student named Kim Yoo Jin. Her body grew cold on my back. She was my first student, but I made her die. – Kang Se Chan

Episode 16.

I told her to trust me. I told her I'll be there for her until the end. – Kang Se Chan

In this world, there are many things that are more important than studying. – Jung In Jae

No matter what you learned from school, it's useless if you don't know what you've done wrong or when to apologize. – Jung In Jae

Yi Kyung: We're not going to give up on you.

Ji Hoon: We promised to graduate together.

What good is it to teach them right from wrong at school? Parents tell them everything is okay at home. – Yoo Nan Hee

I think being a teacher gives us a chance to hold on to students. But at the same time, it's easy to lose them too. – Jung In Jae

I should skip work more often if I want to make you worried about me. – Kang Se Chan

Nam Soon: At least we only bullied other bullies.

Heung Soo: Are you proud, you bastard?

I need to sever ties as soon as possible. – Kang Se Chan

You tried so hard to make me stay. And yet, you're leaving like this? – Jung In Jae

I knew how he lived, but since he comes to school looking fine I thought everything was okay. – Jung In Jae

One is responsible for dealing with one's own life. – Kang Se Chan

What's the difference between losing them and letting them go? Losing them hurts you but letting go doesn't? – Jung In Jae

Things that go wrong in this world never happen because of one person's fault. – Jo Bong Soo
