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?!
