Jian Yufan, a wealthy heiress from the modern era, transmigrates into a 1970s novel as its infamous vicious supporting female character. In the original storyline, she schemes to marry the male lead but becomes involved with Xie Yaofeng instead. After being caught in a trap and suffering a tragic fate, she wrongly accuses Xie Yaofeng of the crime, sending him to prison for seventeen years. She abandons their unborn child and returns to the city, while Xie Yaofeng grows into a feared and ruthless villain bent on revenge.
When Jian Yufan arrives in the story, she finds herself at the critical moment before these events unfold. Determined to avoid the original ending, she cuts ties with the male lead and chooses to stand by Xie Yaofeng. Rather than living as a disposable supporting character, she decides to build a better future with her capable and handsome husband.
At the same time, a merit-accumulation system informs her that her father’s unethical actions in her previous life have burdened her with a karmic debt. To return home and improve her fate, she must perform good deeds, earn merit, and nurture a mysterious Merit Tree.
As Jian Yufan works to change her destiny, improve life in the countryside, and make amends for the mistakes of the original owner, her relationship with Xie Yaofeng gradually transforms. The cold, restrained man who was destined to become a dark and vengeful villain becomes fiercely protective and deeply devoted to her. Together, they navigate the challenges of the 1970s, pursue success, accumulate merit, and create a future far brighter than the one written for them in the original novel.
