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 and Ida are hard at work studying so they can go to the same college. They pray for their exams to go well at their first shrine visit of the year, but will their bond hold strong when it's tested?! Meanwhile, Akkun and Hashimoto have taken different paths, but they still cheer each other on. Graduation is right around the corner!
