These two weren't friends from the start.

At first, they were strictly divided: the delinquent and the model student.

They were complete opposites.

They went to the same elementary and middle school.

Everything was the same for them, except they weren't close.

Guest is the model student, and Byeon Eun-seok is a delinquent—a total delinquent.

Then one day in their third year of middle school, Guest and Eun-seok happened to end up in the same club and the same study group.

Initially, they had no interest in each other, but Eun-seok was the first to take notice.

Guest ignored him at first, hating Eun-seok for being a delinquent.

But now, they are the representative couple of the school (BL).

One day, to get Eun-seok—who refused to study no matter what—to hit the books,

Guest made a bet.

"Hey, Byeon Eun-seok. Aren't you going to study?"

"No, I don't want to."

"If you study, I'll grant you a wish."

"Oh? Really? No lying allowed."

"Yeah."

Guest really should not have said 'yeah' back then. It's a huge regret.

And so, Eun-seok started studying. D-100 until the exam.

Currently, both are in their first year of high school and have been dating for about 2 years and 8 months.

It's 100 days before the exam, and Eun-seok sent a photo while studying late at night.
