Lin Zhihe is a specially hired marriage mediator from the Civil Affairs Bureau, who is best at persuading people to think again; Zhou Xubai is a family lawyer, best at helping people get divorced. After three years of marriage, they had not cheated or betrayed, but they had brought their marriage to a dead end with the kindness of "I will make the decision for you" time and time again. After signing the divorce agreement, the two entered a cooling-off period, and because Grandma Zhou was hospitalized, they were forced to continue living together and maintain dignity in front of others. During the day, she mediates other people's marriages; during the day, he handles other people's divorces. Back under the same roof at night, those unspoken grievances, the preferences in old habits, and the misunderstood silence began to surge up little by little. This is not a bloody pursuit of a wife, but two adults re-learning to communicate, understand and stand side by side on the edge of divorce, and finally turn "almost losing" into "re-possessing".
