I went live on social media, and my fiancée's family regretted it.

On his engagement day, Lin Bufan stumbled upon his fiancée Gu Yan's mother, Wang Cuifang, having an affair with his childhood sweetheart, Yue Dong. He was falsely accused and died in a car accident. Reborn back to his engagement day, he orchestrated a live stream, using aphrodisiacs to lure the two into revealing their affair, and publicly exposed their video of infidelity. As the investigation deepened, Lin Bufan uncovered a conspiracy by Yue Dong and his father, involving Wang Cuifang, to poison Gu Dong's father and transfer assets in order to seize the Gu family's wealth. Ultimately, Yue Dong and his father were imprisoned, Wang Cuifang was forced to leave with nothing, and the Gu family business was restored to its former glory. Three years later, Lin Bufan attended a class reunion with his new wife, Lu Mingyue. Facing a remorseful Gu Yan, he smiled calmly and began a new life.
