On the last day of summer, Yamashita Aoi received a sudden confession from a handsome guy.
This handsome guy turned out to be the "Cotton Candy Prince", who is supposed with a handsome face - but he is a total fluffhead. Aoi decided to completely turn him down, but the one who confessed himself forgot all about the confession, a total airhead..!?

This is a slightly bitter yet sweet and sour youth story revolving around baseball club manager Aoi who gets swayed around by the "Cotton Candy Prince".
