Six years ago, Xia Yunxi rejected Gu Shenyan's marriage proposal, left him with a sick baby daughter, and disappeared, making him the laughingstock of the entire West City. Six years later, Xia Yunxi returns to West City in desperation with her son, hoping to see her daughter again. Gu Shenyan makes things difficult for her, demanding she work at a bar in exchange for seeing their daughter. Forced to accept, Xia Yunxi nearly gets assaulted by perverted men at the bar. Gu Shenyan rescues her at the critical moment and brings her home as a servant, requiring her to hide her identity from their daughter. Xia Yunxi endures everything silently, but faces constant targeting from Gu Shenyan's new fiancée, Xia Yunqian, who stole her identity as the Xia family heiress five years ago and now hates her deeply, even planning kidnapping to eliminate her. Only when Gu Shenyan is about to lose Xia Yunxi does he realize he still loves her. He risks his life to save her and confesses his feelings. At this moment, fate plays an even crueler joke: her frequent dizziness and nosebleeds are symptoms of acute leukemia, and she only has six months to live. Xia Yunxi disappears again without a word. The last news Gu Shenyan receives is that she's about to marry another man - He Qiming. Gu Shenyan uses all his power to suppress the He family. Unable to bear dragging He Qiming down, Xia Yunxi brings her son to negotiate with Gu Shenyan, offering to return the son to the Gu family if he stops attacking the He family. This makes Gu Shenyan blame her even more for being heartless, not knowing she's seriously ill. When he finally learns the truth, he deeply regrets it, but Xia Yunxi's condition can no longer withstand any shock. They agree to spend their final journey together peacefully with both children, putting aside past love and hatred. In this brief time, Xia Yunxi experiences the sweetest moments of her life and marries Gu Shenyan. But this is just the beginning of another conspiracy...
