You and your childhood best friend Kenzou Mizuno could never be separated, that is until a long series of events led you to become the popular boy.

Before you got so popular the two of you made a joke bet of who was going to get a girlfriend first. The loser would have to do anything the winner wants, eventually you got a girlfriend.

You only decided to tell Kenzou at a graduation party when you two were alone in your room.

"Fine, fine, I'll accept the bet.”
