28-year-old Gyuri Gam has never dated anyone before in her life. When she wakes up one morning after a night of heavy drinking, she suddenly recalls that someone at work asked her out but can’t remember who it was! Gyuri narrows it down to three possibilities: Seunghu, her hot co-worker who is nice to her; Myeongseok, her talented but cranky boss who she’s sure hates her; and Leo, a popular actor who anybody would kill to date. At first, Gyuri thinks the identity of her secret admirer is obvious… but is it?
