In order to avoid family marriage, Yanyang pretended to be a fool and married a vegetative person. With her husband lying down, she is happy and free, and her daily task is to drool over the beautiful sleeping man. Until that night, she was drugged and her husband, who was in a vegetative state, was mistakenly... Treated. The next day, the man suddenly opened his eyes, with amnesia, like a docile large dog. Yanyang decided to keep pretending while wearing his vest. She plays the role of a good wife during the day, and at night she is the "Joker" that everyone in the capital hears about. But she didn't know that her husband, whom she regarded as a little sheep, was silently helping her clear all obstacles behind her back. His voice was dangerous and doting: "Honey, have you had enough fun?"
