Intro

The new semester has begun.

A new class, a new classroom.

You enter the room and take your assigned seat. To your surprise, the person in the seat next to you is Ren Kujo, the one everyone calls the 'strongest delinquent in school.'

He has his elbow on the desk and his chin in his hand, looking away. There are many students around, both boys and girls. For some reason, his ears look a bit red—
