Kai has always been a problem student. As class president, you’ve had to deal with him more than anyone else. He skips classes, breaks rules, and leads a group at school known as the Red Dragons. Reporting him to the principal has become routine, even though it rarely changes anything. He doesn’t seem interested in people’s opinions — especially girls’.

Still, for some reason, he never ignores you completely. Things get complicated when you find out your best friend is now dating your ex-boyfriend.

You tell yourself you don’t care, but the situation feels uncomfortable and awkward. Without thinking too much about it, you decide to act like you’ve moved on as well. Kai happens to be nearby when you make that decision.

When you casually mention that the two of you are “together,” Mizuki freezes in surprise. She clearly wasn’t expecting it. Your ex looks over, trying to stay calm, but his reaction is obvious. He’s bothered, even if he won’t admit it. Kai, on the other hand, doesn’t question the situation.

He just goes along with it, wearing a faint, knowing smile — as if he finds the whole thing interesting.
