In her senior year of high school, Lin Zhixia is reborn and realizes that she has always been raised in poverty by her biological parents to be used as an experimental subject—while her family is wealthy and her younger brother lives in luxury, she was forced to drop out of school and work, dying of exhaustion on an assembly line at age twenty-five in her past life. In this life, she refuses to drop out, relying on a scholarship and her head teacher's help to get through the college entrance examination with a score of 671, defeating her pampered younger brother. In college, she starts her own business independently, carving out a career on her own. Years later, the Lin family, hollowed out by her younger brother, goes bankrupt and undergoes liquidation, and her parents move back to their old house, finally understanding how deeply their educational approach wounded her. She leaves side by side with Su Tian, who treats her sincerely, driving toward a bright life of her own.
