Qiao Shuyi, a woman who has loved Gu Linchuan for over a decade, finds herself on the verge of death on her wedding night. Gu Linchuan, her new husband, reveals his true nature by accusing her of causing the death of his beloved childhood friend, Liang Man. In a fit of rage and hatred, he douses the wedding room in gasoline and sets it ablaze, locking Qiao Shuyi inside to burn alive. As she suffocates in the flames, a figure bursts through the door to rescue her. It is Sheng Yu, a man she had previously rejected, who sacrifices himself to save her life. However, Qiao Shuyi dies in his arms, only to awaken five years in the past, on the day of her engagement to Gu Linchuan.
Reborn and armed with the memories of her tragic past, Qiao Shuyi makes an immediate and decisive change. When Gu Linchuan abandons their engagement party to attend to Liang Man, who had faked a minor injury, Qiao Shuyi does not wait for his return as she did in her previous life. Instead, she publicly cancels the engagement, shocking both families. Her father, Qiao Jianye, supports her decision, marking a significant departure from the passive acceptance she showed before. Qiao Shuyi resolves to cut ties with Gu Linchuan and the Gu family, determined not to repeat her mistakes.
The core conflict arises from Gu Linchuan's obsession with Liang Man and his subsequent hatred toward Qiao Shuyi, whom he blames for Liang Man's death in the previous timeline. In this new timeline, Gu Linchuan attempts to return to the Qiao family, claiming his absence was due to a friend's car accident. Qiao Shuyi, however, exposes his lie by revealing Liang Man's social media post from the hospital, proving that Gu Linchuan was with another woman. The Gu family's attempt to salvage the alliance through manipulation fails, and Qiao Shuyi firmly rejects Gu Linchuan, declaring that she no longer loves him.
Amidst this turmoil, Qiao Shuyi reevaluates her relationship with Sheng Yu. In her past life, she had ignored his deep affection for her, focusing solely on Gu Linchuan. Now, remembering his selfless sacrifice, she seeks to understand him better. She visits Sheng Yu's home, where she finds him waiting. Their interaction is tentative but charged with unspoken emotions. Qiao Shuyi hints at her changed feelings, suggesting that age and status are irrelevant to her, which subtly encourages Sheng Yu to pursue her. Meanwhile, Sheng Yu's sister, Sheng Tang, remains a loyal ally, fiercely protecting Qiao Shuyi from Gu Linchuan's advances and the Gu family's schemes.
The story also introduces Liang Man as a persistent antagonist. She appears at a celebration party hosted by Cen Xi, working as a server. Liang Man attempts to manipulate Qiao Shuyi by claiming Gu Linchuan loves her and asking Qiao Shuyi to step aside. Qiao Shuyi dismisses her, calling Gu Linchuan trash and wishing Liang Man happiness, effectively neutralizing Liang Man's attempt at emotional warfare. The narrative highlights Qiao Shuyi's transformation from a naive, devoted girlfriend to a confident, independent woman who refuses to be a victim. She begins to explore her own career interests, moving away from the path of simply taking over her family's business to please Gu Linchuan. As she navigates this new reality, Qiao Shuyi focuses on building a life free from the toxicity of her past, while Sheng Yu watches her with growing admiration and affection, setting the stage for a potential romantic union between them.
