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 has a crush on Ida, a boy in his class. Hashimoto's eraser, which caused so much confusion among friends when Aoki borrowed it, is also at fault for making him flunk a quiz! Aoki, Akkun, and Hashimoto meet up at Ida's for a study session where Aoki and Ida talk about what they are to each other--if they can figure it out?!
