"If you promise to be my booty call, I'll stop fooling around with all those girls." Yu Kamimaeda's an idol with perfect singing and acting skills, but he's also pig-headed and rude. He's the top idol at the talent agency Sae Motomura works for. She's the kind of plain-looking girl who's not interested in make-up or fashion, and Yu's not her type at all. Usually, Sae wouldn't interact with a guy like him outside of work... but when she barges in on him getting busy with another girl at the office one day, he forces her to finish what they started!! The devilish Yu coerces her into bed with him, and then he begins to teach her all about the pleasures of ecstasy.
