Don't be cruel. Volumes 3 & 4 - Yonezou Nekota

Playboy Maya catches studious Nemugasa cheating on a test, and to ensure his silence Maya blackmails Nemugasa into doing whatever he wants! Maya and Nemugasa are now officially lovers, but it's the summer of their third year of high school, meaning even more studying for college entrance exams. Their relationship is reduced to stealing kisses over lunch recess and the occasional sleepover. Stressed and desperately wanting some alone time, the two wind up having a massive-even dangerous-misunderstanding! Things only get worse when the two eventually end up attending separate colleges, meaning they will no longer see each other every day. How will Nemugasa handle Maya's continued popularity with the ladies? And can Maya accept Nemugasa making a new college friend?
