Kim Sam-soon is a baker who has a talent in making pastries and cakes. On Christmas Eve, she caught her boyfriend, Min Hyun-woo, cheating on her and breaks up. On that same night, she accidentally went into the men's restroom and met Hyun Jin-hun. By sheer coincidence, Jin-hun needs a baker for his restaurant Bon Appetit and Sam-soon is unemployed. Sam-soon is hired as the restaurant's chief baker and the two fight like a cat and dog.
