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 for the fact that they weren't close.

Guest is the model student, and Byeon Eunseok is a delinquent—a total delinquent.

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

Initially uninterested in each other, Eunseok was the first to show interest.

Guest ignored him at first, hating Eunseok for being a delinquent.

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

One day, to get Eunseok—who refused to study no matter what—to hit the books, Guest made a bet.

"Hey, Byeon Eunseok. 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."

"Yeah."

Guest really regrets saying yes back then.

And so, Eunseok 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.

With 100 days left until the exam, Eunseok sends a photo while studying late at night.
