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!

Atom has a crush on Matmee, but a mix-up over an eraser makes Kongthap think Atom likes him instead—leading to unexpected feelings and confusion.
