Accidentally Becoming the Female Supporting Character from the 1980s; and the Ex-Fiancé Wants Me to Farm

Zhou Yumiao transmigrates into the body of a girl with the same name, who was beaten to death by her cruel grandmother for stealing an egg. The original Zhou Yumiao was the fourth daughter of a patriarchal rural family, neglected since birth and forced into servitude. She had an engagement to Lu Anhe, a wealthy young man from the city, which was her only hope of escaping her abusive home. However, in the original story, Lu Anhe came to break off the engagement, leading to her desperate attempt to force him into marriage, which resulted in her tragic death. Armed with knowledge of the novel's plot, Zhou Yumiao prepares to let the engagement fail, hoping to avoid the disastrous fate of the original protagonist.

When Lu Anhe arrives, he intends to end the engagement but is unexpectedly bound by a mysterious Quick Q&A System that also connects to Zhou Yumiao. The system forces both of them to answer agricultural and survival questions, punishing incorrect answers with physical pain. During their confrontation, Lu Anhe is forced to his knees by the system's punishment, allowing Zhou Yumiao to negotiate a breakup fee of one hundred yuan. Instead of leaving, Lu Anhe decides to stay at the Zhou household to investigate the source of the system, claiming he wishes to spend time with his fiancée. He pays for his room and board, much to the greed of Zhou Yumiao's grandmother, who sees an opportunity for a higher bride price.

Zhou Yumiao's family continues to mistreat her, forcing her into hard labor and denying her basic needs. Despite this, she begins to assert herself, refusing to accept the cowshed as her living quarters and instead sharing Lu Anhe's room. Lu Anhe, initially disgusted by her poverty and the rural conditions, gradually witnesses her resilience and intelligence. He defends her against village gossip and her abusive cousin, Zhou Chengming, showing a protective side that surprises Zhou Yumiao. Their relationship shifts from mutual disdain to a tentative alliance, bound by their shared connection to the system.

As they navigate daily life, Zhou Yumiao uses the system's rewards, such as food and storage space, to improve her circumstances and help Lu Anhe. He, in turn, provides her with material support, including new clothes and money, while learning to adapt to rural life. The couple faces various challenges, from dealing with leeches in the rice fields to confronting the family's hostility. Lu Anhe's presence disrupts the Zhou family's dynamics, as they fear losing his financial contributions while resenting his interference in their treatment of Zhou Yumiao.

The story follows their evolving partnership as they uncover more about the system and their past lives. Zhou Yumiao learns to value herself, rejecting the submissive role imposed by her family. Lu Anhe discovers strength beyond his privileged upbringing, finding purpose in protecting Zhou Yumiao and solving the mysteries of their shared fate. Together, they face the prejudices of their community and the dangers of their new environment, building a foundation for a future that defies the original novel's tragic ending.
