Lin Jianwei owns a home in the city. While staying with her, her younger cousin, Xu Manning, crosses boundaries by moving Jianwei's work materials without permission and damaging them. Manning then joins forces with her aunt, Zhou Xiufang, to guilt-trip Jianwei into letting her stay indefinitely, even spreading rumors that she has been kicked out. Lin Jianwei stands firm on her personal boundaries, insists that her cousin move out as agreed, and withstands pressure from relatives one after another. In the end, she welcomes her mother into her home and establishes clear boundaries for dealing with relatives.
