Lin Xiaomai, an ordinary private kitchen chef, is used as Bai Yueguang's substitute by wealthy young master Shen Ye, and is trapped in a 24-hour time loop on the day of the engagement party. Every time at midnight, everything resets, and she dies either by accident or murder. After her fifth death, she decided not to run away - but to use a pot of osmanthus cake, a bowl of soothing soup, and food as a key to pry open Shen Ye's frozen sincerity. When the cycle repeated for the 49th time, she discovered a shocking secret: she was not only a substitute, but also Bai Yueguang's lost twin sister. This time, she wants to regain not only her own name, but also her "only" position in the eyes of that man in the last cycle.
