Now, as she prepares to begin a new life through remarriage, her younger brother pressures her at a family dinner to give her retirement home to her nephew as a marital home. Faced with her mother's favoritism and her siblings' endless demands, she finally stops giving in. She takes back the spare keys, redistributes responsibility for caring for her mother, and refuses to keep bailing out her family. Her partner, Zhou Jianmin, consistently respects and supports her. Torn between family ties and her own well-being, Xu Xiulan struggles to establish clear boundaries and responsibilities within her family. Through real-life experiences, her relatives gradually come to their senses. At last, Xu Xiulan breaks free from decades of obligation, protects her home and marriage, and begins living life on her own terms.
