Don't Be Cruel: 2-in-1 edition part 2 contains volumes 3 and 4 and features story and art by Yonezou Nekota.

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?
