“Can you sleep with me just once?” Se-In, who has assisted Director Shin Tae-Heon for three years, spends an impulsive night with him. She planned to leave coolly for an overseas branch, but after that night, he started acting strangely. "Am I the only one bothered by Secretary Yun?" Not content with just clinging, he admits, "I've come to want Yun Sein." He doesn't hesitate to make bold statements, asserting, "Make me yours. Or I can make you mine." He has become shamelessly forward. Director, why are you doing this to me... A disaster sparked by a one-night stand. The overwhelming pursuit by a man too perfect begins.
