Lin Xiulan lived with her son Zhou Zhiyuan and daughter-in-law Sun Huimin for three years, helping them pay off their mortgage, subsidizing household expenses, doing laundry and cooking, only to be accused by Sun Huimin at her birthday banquet of living off them for free and forcibly demanding an AA split. With a cold heart, Lin Xiulan decided to follow the rules to the end, stopping subsidies, letting each live their own life, and refusing to sell her house to help fill her son's debts. As Zhou Zhiyuan and his wife repeatedly demanded money and real estate, and even used a fake illness to extort compensation, Lin Xiulan finally saw through the endless extraction in this family affection. She returned to the county town, rediscovered dancing with the company of her daughter Zhou Xiaoning and old sisters, won a competition, and learned once again to spend money on herself and live for herself.
