It tells the story of Lin Yue and Gu Chuan reflecting on whether they should continue their marriage during the cool-off period of their divorce. In the first New Year after their flash marriage, the conflict between the extremely chauvinistic husband and the independent and casual wife became more intense, and they had the idea of divorce. When the cool-off period of divorce coincided with their return home for the New Year, they had to reach a consensus on hiding the matter from their parents due to a man-made accident. While preparing for the New Year, the two discovered that their parents also had the idea of divorce. The two generations of couples played a game of "white lies", each concealing their contradictions and trying to deal with the New Year with superficial peace, but they achieved understanding and tacit understanding between the two generations of couples within 15 days, and ushered in a new chapter of love for each other when the New Year bell rang.
