After transmigrating, I became the male lead's gold-digging girlfriend

Ji Rou, an ordinary office worker, dies saving a child and transmigrates into the body of a novel character with the same name. In this story, the male lead Shen Xingbai is reborn after his leg is shattered at a construction site. Armed with the "Golden Eye" ability to see through objects, he rises from poverty to build a jade empire, seeking revenge on his gold-digging ex-girlfriend who abandoned him. Ji Rou finds herself inhabiting the body of that very ex-girlfriend, destined to be humiliated and destroyed by the reborn Shen Xingbai. Determined to avoid her tragic fate, she resolves to change her destiny by preventing the original betrayal and making amends with Shen Xingbai before the plot unfolds.

On Valentine's Day, the day before Shen Xingbai's accident, Ji Rou rushes to the construction site to stop him from being injured. She pushes him out of the way of a falling steel bar, but her new body lacks the strength to move him completely. Shen Xingbai sustains a minor scrape but collapses due to the merging of his past-life memories. Upon waking in the hospital, he realizes he has been reborn again, this time with his Golden Eyes intact. He immediately suspects Ji Rou of also being reborn due to her unusual behavior, such as visiting the construction site and saving him. His attitude toward her shifts from pure disgust to cold suspicion and possessiveness, as he refuses to break up with her despite her attempts to distance herself.

Ji Rou navigates her new reality by exposing her dormmate Wu Xiaomei, who has been manipulating the original Ji Rou and secretly involved with a wealthy playboy, Young Master Bai. Ji Rou turns the tables on Bai by switching his drugged wine, causing him to assault Wu Xiaomei instead. She then leaks the scandal to the press, ruining both their reputations. To secure her financial independence and avoid relying on Shen Xingbai, Ji Rou joins a talent selection contest organized by an entertainment company, aiming to win prize money. She also reconnects with Xu Qingmei, the novel's female lead, repairing the friendship that the original Ji Rou had ruined through Wu Xiaomei's influence.

Shen Xingbai, utilizing his Golden Eyes, begins making fortunes in the jade market and gains the attention of powerful families like the Nalan clan. He attends an auction where he helps the Nalan family avoid a costly mistake, securing his position in the elite circle. Meanwhile, Ji Rou is forced to meet Young Master Zhou, another wealthy heir schemed by Wu Xiaomei. Ji Rou uses a stun baton to repulse Zhou's advances and exposes his predatory behavior, leading to further scandal for Wu Xiaomei. When Ji Rou accidentally runs into Shen Xingbai at the same hotel, he confronts her, misinterpreting her presence as an attempt to flirt with other men. His jealousy and possessiveness escalate, leading to a physical confrontation where he carries her away and kisses her forcefully, blurring the lines between revenge and obsession.

As the story progresses, Ji Rou continues to try and prove her loyalty to Shen Xingbai while managing her own career and friendships. She sells luxury goods bought by the original owner to fund her life and participates in the talent contest, where she encounters the novel's heroine, Zhang Xiaoxiao. Despite Zhang Xiaoxiao's initial hostility, Ji Rou handles the situation with grace, earning respect. Shen Xingbai remains watchful and suspicious, his feelings a complex mix of past resentment and current attraction. Ji Rou is caught in a precarious position, trying to survive the revenge of a reborn male lead while inadvertently altering the plot and drawing him closer through her genuine efforts to change.
