My Love Mix-Up!, Vol. 1

In this warmhearted romantic comedy, 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!
