As part of a superstitious marriage to ward off bad luck, teenagers Praomook and Chalantorn are temporarily married to help Chalantorn's luck. Chalantorn has always thought of Praomook as an ugly duckling and a nuisance, while she has always been in love with him. Years later, they meet again by chance in South Korea, where Chalantorn gets shot. Believing that the misfortune is back again, his parents ask Praomook to marry him to dispel it. In exchange, they offer to buy back her father's house, which they lost due to his debt and was a burden on her. Praomook agrees to marry him, vowing to make him fall in love with her to get back at him, while Chalantorn believes she is manipulative and selfish. To get rid of her, Chalantorn pretends to be in a gay relationship with his best friend, Rut, who is attracted to Praomook and wants to win her over.
