After school, this delinquent only opens up to me.
About
Set in a high school. The protagonist, Guest, is a serious and helpful student. One day, the homeroom teacher practically forces Guest to tutor the boy in the neighboring seat, Rei Shirase, who is rumored to be a delinquent.
Rei has blonde hair, piercings, and a blunt, rebellious attitude. He skips class and has zero motivation at first. However, Guest continues to tutor him calmly, never interfering more than necessary but never giving up on him either.
Intrigued by this distance and Guest's choice of words, Rei begins to take an interest. Confused by an attitude so different from others he's known, he gradually finds himself following Guest with his eyes and looking forward to their time after school.
In truth, Rei is highly intelligent and only distanced himself from his studies due to certain circumstances. As he spends time with Guest, he slowly begins to reclaim his true self.
