Su Wan, the "Urban Sea King" who owns three Internet celebrity flower shops, was forced to sign an agreement with Shen Jin, the owner of a small restaurant, to play the role of his fiancée because his grandfather was seriously ill. Shen Jin looks funny and sassy, but she has the aura of a cooking god when she is in trouble. She has repeatedly stood up when she was harassed by gangsters and made things difficult for her love rivals. Su Wan maintains the persona of "Sea King" externally, but in his heart he only has a secret crush on Shen Jin, and Shen Jin has long been attracted by her hard-spoken and soft-hearted appearance. When a vengeful ex-boyfriend disrupts the situation and a jealous rival stumbles, Su Wan uses the flower shop as a shield and slaps her in the face with wisdom and elegance. The two reveal their secret love in a fake show, transforming from an agreement couple into a two-way love, turning their small life into a romantic poem intertwined with flowers and food.
