In her past life, Zhou Ning investigated the tens of thousands in online loans hidden by her prospective sister-in-law Gu Wei for her younger brother Zhou Chuan, and slammed the evidence on the dining table. The marriage fell through, and from then on Zhou Chuan changed jobs one after another, dated one partner after another who broke up, and every time things went poorly he turned back to curse his sister for ruining him. Her parents blamed her for being too ruthless, sabotaged her job, and used cold violence to force her to admit her mistake. On New Year's Eve, Zhou Ning died alone of illness in a rented room, with eighteen phone calls going unanswered.
