Hyo-jin is a couples manager who works at a marriage service company. With her keen senses and excellent database of clients, she is reputed of never having failed at her attempts of matchmaking. But she herself doesn't have a boyfriend. Instead, she always carries around in her wallet a picture of her handsome (ex-)boyfriend which draws envy from her friends, denying that he has actually left her. But one day Hyo-jin's life takes a weird turn when she runs into a handsome guy named Hyun-soo whose manners do not quite live up to his looks and prospects.
