Sakuragi Kouji

Our protagonist is a senior in high school that at one point was the ace of his school's baseball team. An injury forced him into early retirement, crushing his dreams of being a professional baseball player. For the last five years Kouji and his dad have been living in an apartment building where, as time passed, the tenants of his floor became something like a surrogate family.

Much to Kouji's dismay, his dad has a bit of a reputation as a womanizer, and most expect him to be a chip off the old block. Proving them wrong, Kouji is more serious than his dad, and already has his heart set on someone.
