Before she transmigrated, Rong Yu was a respected mathematician who died unexpectedly at an awards ceremony. Before transmigrating, she had also been hit by a car while saving her eight-year-old son. After transmigrating, she discovers that she has possessed the body of an eighteen-year-old Rong Yu, whose life has been full of hardship. Raised in the countryside, she was brought back to her father's home after her mother died, where she was often bullied by her stepmother and half-siblings. She also suffered from severe depression. Then she realizes that the son who was eight back then has grown into the seventy-something chairman of the Ji Group, making her a great-grandmother.
