An ordinary dinner is the last straw for Cheng Zhiyuan. His maternal grandmother and mother look down on his paternal grandmother because she comes from the countryside and is considered incapable, yet they have forgotten that some of the money that built this family came from her hard-earned savings. Watching his grandmother wait for someone to invite her before she can even sit down at the dinner table, he decides to stand up for her and demand justice. But bringing his elderly grandmother into the house is easy; getting the family to truly accept her is another matter. Faced with his mother's constant concessions, his father's silence, and his maternal grandmother's disapproval, Cheng Zhiyuan gradually realizes that his grandmother needs more than just a bedroom. She needs a warm meal that she can enjoy without having to read everyone else's mood. The grievances that have long been swept under the rug will force the entire family to confront their relationships with one another.
