In this warmhearted romantic comedy, a mistaken identity leads to a blossoming romance between two boys.

Aoki has a crush on Hashimoto, the girl in the seat next to him in class. But he despairs when he borrows her eraser and sees she’s written the name of another boy—Ida—on it. To make matters more confusing, Ida sees Aoki holding that very eraser and thinks Aoki has a crush on him!

Aoki is dating Ida, a boy in his class. In order to buy Ida a birthday present, Aoki started working part-time, but now it seems Ida doesn’t want Aoki to spend his hard-earned money on him. What’s a boyfriend to do?!
