Adults have secrets. One night, after hearing a scream, Takimoto Kaoru is suddenly held tightly by someone in complete darkness. He was too surprised to retaliate, but the smell that tickled his nose was… Sakumra-kachou?! In addition he tells him to “sleep with me tonight”?! Takimoto, who couldn’t refuse an elite superior is now being used all over the place! And the appearance of a troublesome yandere ikemen Iwase Yuutarou doesn’t help either. A bitter love, where the guys’ wounds and secrets overlap, is here.
