Twenty-one-year-old Shi Chu is a senior student in the Department of Mathematics at Nankai University. She has a broken family: her biological father Yan Mingzhi divorced and disappeared after getting married, her mother remarried Feng Jianguo, her stepfather cheated on her with Zhang Yao and gave birth to her sister Feng Ruxing, and they eventually divorced. Her grandfather and grandmother passed away one after another, and she was used to bearing everything alone since she was a child.
Shi Chu discovered that her stepbrother Feng Xia had been stealing her underwear for a long time, and even stole two-year-old Ruxing's. She once told her mother, but at the time there was a lot of turmoil at home over the affair, so no one paid attention.
One day after graduation, six-year-old Ruxing disappeared in an amusement park. When Shi Chu found her, the child was lying disheveled in the grass - Feng Xia and two others raped her. Not long after, Shi Chu was hit by a van that ran a red light on a snowy night, and his right calf was amputated. The people in the car were Dao Die and Huang Xiaohui who were escaping. She clung to the two men and they were eventually captured.
With Cao Ci accompanying him throughout the process, Shi Chu was fitted with prosthetic limbs, moved out of the dormitory, and moved into Cao Ci's home. She continued to go to school, worked as a tutor, and was admitted to Peking University as a graduate student. Feng Xia and others finally faced trial, and Shi Chu and Cao Ci also came together day after day.
