Child X Adult Equation

Chiharu and Satoshi are childhood friends since preschool. Raised as the only son of the Nanjou family, Chiharu was a crybaby. Satoshi on the other hand was a tough, rambunctious child who loved playing soccer more than anything else. Nowadays Chiharu is popular with the girls, unlike Satoshi. But he has a secret crush that he can't let anyone know, especially Satoshi.
