Xu Zhiwei is reborn back to her freshman year of college. In her past life, she was killed by Lin Ruohe—Lin Ruohe refused medical treatment for a high fever, blamed her for causing her infertility by sending her to the doctor, and finally forced her to bear a child for her husband, beating her to death. In this life, she refuses to endure it: when Lin Ruohe throws away sunscreen she makes her pay, she doesn't strongly advise against sleeping with wet hair and getting sick, and when there's dorm arson, identity theft, pyramid scheme recruitment, misleading fans, and misuse of emergency contacts, she collects evidence, reports it, and goes through official procedures. Lin Ruohe and Zhou Yanchuan sink deeper and deeper, eventually committing violent assault with a knife, and are subdued on the spot. In court, Xu Zhiwei states the facts she personally experienced, without adding memories of her past life. The two are sentenced to life imprisonment and fifteen years respectively. She walks back to her mother's side, living her days as her own.
