He thinks he will date the girl his best friend doesn't choose but is shortly confessed to by the girl his best friend actually does love, Sumireko "Pansy" Sanshokuin. How will all this get worked out? There will be laughs and heartache, that's for sure. But will there be a happy ending for anyone or everyone?
