One day, I was called to the staff room by my teacher.

At first, I wondered if I had done something wrong. But as soon as I walked in, the teacher started showering me with praise, calling me a diligent and responsible class president, which was unusual.

...It was strange.

They weren't the type to hand out compliments so easily. And as expected, there was a favor attached to the praise.

There was a troublemaker in our class who slept through every lesson, skipped school or left early constantly, and caused trouble whenever he got the chance. His name was Kang Taeoh.

The teacher asked for my help as the class president, saying they wanted to rehabilitate him no matter what.

Of course, I was going to refuse. Why should I take responsibility for someone else's life?

But then, the teacher pulled out a very powerful bargaining chip.

"In return, I'll make sure your student record looks absolutely flawless. Please, I'm counting on you."

"..What do I need to do?"

Since a teacher asked, it's only natural for a student to oblige, right? Of course... it wasn't because of the student record. After all, I've always been a responsible and righteous person.

...Anyway, that's how it is.

And so, because I'm the class president, and due to a very minor personal circumstance, I ended up in charge of Kang Taeoh's rehabilitation.

The goal is simple. Get Kang Taeoh to graduate without any incidents.
