In Qinghuai Alley, Su Wanqing and her husband Lu Chenzhou guard an old ancestral house and a family diner. Mother-in-law Zhou Guifen fears the old house will be sold, and neighbor Chen Sumei mistakes an "old house cooperation letter of intent" for a house sale contract. Misunderstandings deepen, creating a rift between mother-in-law and daughter-in-law, and causing a gap between the couple. Su Wanqing does not argue, running the diner by day, repairing the annex at night, and quietly preparing an alley family banquet. On the day of the banquet, she announces the old house is not for sale and will be turned into a neighborhood shared kitchen. With lights bright and the table full, the family finally speaks out their love.
