Ever since she entered high school, Kotoko Aihara wanted to be in the same class as Naoki Irie. The only problem, Irie is the smartest student in school while Kotoko is one of the dumbest. Now in 3rd year high school, she still isn't there. One day, her home gets destroyed and the only place else to go was to Irie's home. Now that she lives close to him, will their relationship be the same, or will it become greater than it is.
