Du Qingyang, a 21st-century medical graduate student, left her 99th message urging her favorite author to update, jokingly cursing that if the author didn't update, she would become the vicious female supporting character in the novel. That vicious female supporting character shared her name, Du Qingyang, and the novel had not been updated for 366 days. When she woke up, the curse had come true, but not for the author. Du Qingyang transmigrated into the novel, becoming the vicious female supporting character in an 80s-set story.Opening her eyes, she found herself in bed, surrounded by a middle-aged couple and a young man with tears on their faces—her parents and brother in this new world. They cried out that she was foolish, that her mother would die without her, that her brother would make Zhu Xuan marry her. Du Qingyang realized these were lines from the novel. In the original story, the vicious female supporting character was deeply infatuated with Zhu Xuan, the Village Director's son, and after relentless pursuit, became engaged to him. When Zhu Xuan fell in love with the female lead, Yao Lin, and proposed breaking off the engagement, the supporting character jumped into a pond to commit suicide.Du Qingyang immediately wanted to return to her own world. She jumped up and rushed to the pond, intending to repeat the suicide, believing it would send her back. However, the pond was shallow, barely reaching her calves. The original owner had fainted from fear of water, not drowned, leading to the transmigration. Du Qingyang was not afraid of water, so this method failed.Her family caught up, threatening to jump with her. Du Qingyang stopped them. She realized she could not go back easily and had to accept her new life. Her brother, Du Feipeng, decided to gather people and confront the Zhu family to prevent the broken engagement. Du Qingyang knew the original plot: her brother would cause trouble, forcing a wedding banquet, but the marriage would later lead to disaster. The original Du family suffered greatly: the original owner died, her mother went mad, her father died depressed, and her brother became crippled. Du Qingyang was determined to avoid this fate.As she walked toward the Zhu family, she accidentally bumped into Xiang Zhihang, a young man in the village who was abused by his adoptive family and bullied by everyone. Du Qingyang recognized him from the novel as a future big shot who would be taken in by his wealthy biological parents at age 18. She used her self-taught divination abilities, which required physical contact, to quickly read his fortune. Confirming he was destined for rapid advancement, she decided to build a good relationship with him. She apologized for bumping into him and gave him a candy she had intended for Zhu Xuan. Xiang Zhihang was deeply moved, tasting candy for the first time.At the Zhu family home, Du Feipeng and five thugs confronted them. Du Qingyang, to everyone's shock, stepped forward and demanded to break off the engagement herself, declaring that Zhu Xuan was not handsome and that she no longer liked him. She produced a 10-yuan bill as a return of the engagement deposit and presented a detailed list of gifts the Du family had given the Zhus over the past year: pork, hens, eggs. She calculated that the Zhu family owed 62 yuan. The crowd was astonished. The Zhu couple panicked; they had enjoyed those gifts but did not want to pay.Zhu Xuan, eager to be rid of Du Qingyang, agreed to pay. The Zhu family managed to scrape together only 47 yuan. Yao Lin, the female lead, stepped forward and lent Zhu Xuan 15 yuan. Du Qingyang accepted all the money and confirmed the engagement was broken, wishing them a happy life together. She warned them never to break up, ensuring they would not harm others.Du Qingyang took her family away, leaving the Zhu family in debt and embarrassment. She decided to live well in this new world, replacing the original owner, and began to plot a different path for her family, free from the tragedies of the original novel. With her divination skills and knowledge of the future, she started to build connections and change her fate, starting with the kind gesture to Xiang Zhihang, the future big shot.
