Jiang Xiwei was originally a top student expected to become the top scorer in the college entrance examination. However, after the exam, her score turned out to be only 198. She was spurned by her family and pushed off the rooftop by her younger sister, Jiang Xilu. After being reborn, she discovered that Jiang Xilu had bound an exchange system and swapped her college entrance examination results. Therefore, Jiang Xiwei played along and deliberately answered the questions with a red pen, causing Jiang Xilu to get a score of zero. At the top - scorer banquet, the reversal of the scores shocked everyone and led to their condemnation. Subsequently, around events such as the acceptance letters from Tsinghua University and Peking University, Jiang Xilu continued to do evil deeds, while Jiang Xiwei counterattacked skillfully. In the end, Jiang Xiwei proved herself, Jiang Xilu reaped what she had sown, and Jiang Xiwei also won the recognition of her family.
