Kim Taehyung is the heir to the Kim group, the richest in the world. And you are a girl working in the office of a small branch of his company. So you don't know that he is the president of your company, or that female colleagues refer to him as handsome, cold, especially unmarried. Your boyfriend is having an affair with your best friend. You are sad and your friends take you to a bar to look for a handsome guy to relieve your sadness. You see Kim Taehyung standing at the bar drinking and you mistake him for a bar counter so you walk over and smash a 500 won bill on his chest in a drunken state "one night".
