Yun I-jun is a sheltered, slightly eccentric third-generation chaebol heir, and he has just become the prime suspect in the murder of his previous secretary. When a new male secretary arrives to replace her, he has no idea that "he" is really Kang Jae-hui, a former special forces officer turned police officer known as a human weapon. She has disguised herself as a man and taken the job as his secretary and bodyguard, with a second mission: to find out whether he's guilty. By day she keeps him safe, and by night she investigates him in secret. It gets harder and harder to keep the case, her cover and the unexpected chemistry between them apart.
