After My Younger Sister Stole My Fiancé, I Started Selling Goods on an ’80s Live Stream

Su Tian and her cousin Su Lili are reborn with memories of their past lives. In the previous timeline, Su Tian married Guo Zhiwei, a man from a wealthy factory family, only to suffer decades of psychological abuse, infertility induced by the Guo family, and eventual death in misery. Su Lili, conversely, married the abusive gambler Chen Xiaojun and endured poverty and violence. Upon rebirth, Su Lili uses her foreknowledge to snatch Su Tian’s engagement to Guo Zhiwei, intending to force Su Tian into the disastrous marriage with Chen Xiaojun. Su Tian, aware of both men’s true natures, refuses the match and confronts Su Lili’s schemes directly.

As Su Lili prepares for her wedding to Guo Zhiwei, she attempts to blackmail Su Tian into marrying Chen Xiaojun. Su Tian discovers Su Lili’s secret affair with Chen Xiaojun and uses it to extort five hundred yuan from her cousin. During the wedding chaos, Su Tian accidentally injures Qin Yan, Guo Zhiwei’s cousin and a skilled truck driver, while trying to intercept Chen Xiaojun. Chen Xiaojun attempts to assault Su Tian in the reeds, but Qin Yan intervenes, beating Chen Xiaojun and breaking his legs. Su Tian takes Qin Yan’s shirt to cover her torn clothes, marking the beginning of her deviation from her past life’s path.

Shortly after the wedding, Su Tian binds with a livestreaming system called Xiao Ba. The system allows her to sell goods from the 1980s to viewers in the future, with earnings paid in contemporary currency. Her first broadcast sells sixty-one salted duck eggs for a substantial profit. The system reveals that Su Tian can unlock more frequent livestreams by deviating from her original life trajectory. Encouraged by her financial gain and the need to avoid her past fate, Su Tian actively seeks opportunities to change her circumstances.

Using her knowledge of future value, Su Tian hunts for rare Monkey Stamps in the 1980s. She encounters Old Mrs. Li, who needs money for her grandson’s medical bills. Su Tian purchases the stamps at a fair price, securing a valuable asset that she plans to sell through her livestream. Meanwhile, Su Lili settles into her new life with Guo Zhiwei, unaware of the abuse and control that await her. Su Tian maintains a distant relationship with her family, focusing on building her wealth and independence through the livestream system.

The story follows Su Tian as she navigates the complexities of 1980s rural and urban life while leveraging her modern knowledge and supernatural system. She avoids the pitfalls that trapped her in her previous life, such as marrying into the toxic Guo family or falling victim to Chen Xiaojun. Her interactions with Qin Yan, who is intrigued by her sudden change in personality, suggest a potential new romantic path distinct from her past. Su Tian’s primary goal is to secure financial freedom and emotional autonomy, using the livestream income to improve her life and that of her family.

As the narrative progresses, Su Tian continues to exploit the price differences between eras, buying low in the 1980s and selling high to future consumers. She carefully manages her deviations to maximize her livestream levels while avoiding suspicion from those around her. The contrast between Su Lili’s seemingly advantageous marriage and Su Tian’s newfound independence highlights the thematic focus on female agency and the consequences of past choices. Su Tian’s journey is one of strategic avoidance and calculated risk-taking, aiming to rewrite her destiny entirely.

The conflict between the cousins intensifies as Su Lili grows suspicious of Su Tian’s sudden competence and wealth. Su Tian, however, remains focused on her long-term plan to escape the limitations of her environment. Through the livestream system, she gains not only money but also a connection to the future that empowers her to make decisions free from the constraints of her past life. The story sets the stage for Su Tian to potentially confront the Guo family and Chen Xiaojun on her own terms, rather than as a victim.

Su Tian’s rebirth serves as a second chance to correct the errors of her previous existence. By rejecting the roles assigned to her by fate and society, she carves out a new identity defined by self-reliance and strategic acumen. The livestream system acts as both a tool and a catalyst, enabling her to transcend the economic hardships of the 1980s. Her relationship with Qin Yan develops gradually, offering a contrast to the toxic relationships she previously endured. The narrative emphasizes the importance of knowledge and foresight in overcoming adversity.

As Su Tian accumulates wealth and influence, she begins to reshape her surroundings. Her family benefits from her earnings, yet she maintains strict control over her finances to ensure her independence. The story explores the dynamics of rural Chinese society in the 1980s, highlighting the limited opportunities for women and the social pressures surrounding marriage. Su Tian’s success challenges these norms, demonstrating that alternative paths are possible for those willing to break away from tradition.

The overarching plot follows Su Tian’s transformation from a passive victim of circumstance to an active architect of her destiny. Through her interactions with the system, her family, and new acquaintances like Qin Yan, she builds a life that is secure and self-determined. The narrative promises further developments as Su Tian continues to leverage her unique position to outmaneuver her enemies and secure a prosperous future for herself.
