An adult college student visits the same café five days a week, forcing himself to drink coffee he dislikes because he fell for the waitress Airi at first sight. Wanting to grow closer, he gets a job there and, after a month of working beside her, finally gathers the courage to ask her out. She accepts with a seductive smile. He expects nothing more than a pleasant day together, but Airi suggests going somewhere private, takes him to a hotel, and keeps him there for sex until morning.
