By day, Chihiro is a plain office worker, but by night, she's a confident cabaret girl. One day, Junya, a college student who works at her club, shows up at her day job as an intern. Chihiro tries to hide her identity, but when she's ultimately found out, the two somehow end up living together! At the office, Junya is studious and well-behaved, but at home, he's pushy and constantly leads Chihiro by the nose. When Chihiro gets drunk in front of a customer one night, Junya drags her out of the club and plants a biting kiss on her lips, telling her she doesn't understand the effect she has on men. While he pins her down with his body, Chihiro becomes unable to move beneath his passionate gaze. She can't help but succumb to the sweet loving of a possessive younger man...
