I Transmigrated into a Power-Fantasy Novel as the Male Lead's Fiancee Who Breaks Off the Engagement

Mu Jing, a woman from the modern world, dies in a car accident and transmigrates into the body of a female supporting character in a fantasy novel titled Master of Superpowers. In this new world, society is divided between the Mu Family and The Federation, where individuals can awaken supernatural abilities categorized as Elemental, Beast, or Special types. The original Mu Jing was the only daughter of the wealthy Mu Family but suffered from a congenital heart disease. Her father, Mu Jianbai, was overprotective and hostile toward Xu Ge, a poor young man who arrived with an engagement contract. Xu Ge, the novel's male protagonist, had not yet awakened his ability and was subjected to humiliation by the Mu family, which led to his grandfather's illness and eventual death. This sequence of events set the stage for the Mu Family's destruction at the hands of a vengeful Xu Ge, who later awakened the powerful ability to copy other people's powers.

Upon waking, Mu Jing realizes she is in the story at the critical moment when the engagement is broken. Determined to avoid the tragic fate of the original character and her father, she seeks to alter the plot by building a genuine relationship with Xu Ge. She visits him at his part-time job at a courier station and later at the hospital where his grandfather is dying. Mu Jing sincerely apologizes for her family's behavior and offers to cover the medical expenses, framing it as a loan to be repaid. She reveals a childhood photograph showing her mother and Xu Ge's mother were close friends, suggesting that their families' bond should transcend the broken engagement. Although Xu Ge is cold and suspicious, he accepts her help to save his grandfather, who passes away three days later. Mu Jing attends the funeral, standing silently by Xu Ge's side in the rain, which begins to soften his hostility.

Shortly after, Xu Ge awakens his ability after being severely injured while saving a woman from attackers in an alley. Mu Jing discovers he has awakened a rare lightning-type ability, differing from the fire ability described in the original novel, indicating that her presence has altered the timeline. She takes him to a testing center and then proposes a deal: Xu Ge must pretend to be her boyfriend for a three-day class trip to a resort in City C. This arrangement allows Mu Jing to deter other suitors while providing her with a convenient excuse to stay close to the protagonist. During the trip, Mu Jing treats Xu Ge with kindness and respect, buying him clothes, caring for him when he is exhausted, and defending him from harassment by other classmates, particularly a rival named Xin Shi. Their interactions shift from transactional to genuinely friendly, with Xu Ge beginning to trust her intentions.

After the trip, Mu Jing and Xu Ge maintain a friendly relationship as they prepare for university. When Mu Jing is kidnapped by thugs near her part-time job, Xu Ge rescues her, displaying combat skills that far exceed those of a novice ability user. He reveals that he remembers his previous life, having been reborn with memories of his past suffering, and suspects that Mu Jing is not the original person but has transmigrated into the body. Despite this revelation, he does not reject her. Mu Jing enters the Federation University's Special Type Academy, while Xu Ge enrolls in the Ability User Academy. As they begin their new lives, Mu Jing continues to navigate the complex social dynamics of university while working to ensure the survival of her family and the prosperity of the male protagonist, whose path now diverges significantly from the original story.
