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