At the age of forty-five, the successful Liang Wenli breathed her last in the hospital bed, her heart filled with endless regret for her family. She once pushed herself into the abyss step by step because of her rebelliousness, impulsiveness, and lack of understanding of people: In order to avenge her betrayal of her boyfriend and best friend, she was imprisoned for ten years; after she was released from prison, she became addicted to gambling, angered her father to death, and forced her husband Fan Wenchuan and a pair of children away. When she finally woke up and succeeded in her struggle, everything was irreversible. When she opened her eyes again, she was back to the age of fifteen, the rebellious summer when she decided to drop out of school and become an apprentice in a chemical factory. Her body contains a soul that has experienced many vicissitudes of life, and in front of her are her parents who are still young and healthy, her sister who loves her, and Fan Wenchuan, who will become her husband in the future but is still a young boy at the moment. This time, Liang Wenli holds the biggest trump card of "rebirth". She knows the economic trends, industry trends, and even lottery numbers in the next twenty years. But her goal is no longer simply to accumulate wealth, but to make up for all regrets: she wants to stay on campus and arm herself with knowledge; she wants to protect her family and let her father enjoy his old age; she wants to avoid the traps of the scumbag Han Qiang and her plastic best friend Liu Fang, and make them pay for their actions; most importantly, she wants to find the man who broke her heart in her previous life - Fan Wenchuan, get to know him again, accompany him, and make up for him.
