Four years ago, to detoxify, Jiang Shan entered into a contractual marriage with Ling Fengnian, who was dealing with family pressure to marry. Four years later, the toxin is cured and Grandpa Ling passes away, prompting Jiang Shan to propose a divorce. Mistaking it for a change of heart, Ling Fengnian signs the papers and offers compensation, but Jiang Shan transfers the money back and leaves gracefully. After the divorce, Ling Fengnian discovers that his ex-wife holds multiple elite identities: top surgeon, foundation chairperson, combat champion, and haute couture director, prompting him to pursue her back with deep remorse. Meanwhile, the Xiangkan Group—which poisoned her back then—along with the scheming supporting character Qu Jiahui, continuously harm the two. Thanks to You Ziyi stepping in to save them, all the villains are eventually brought to justice, Ling Fengnian proposes, and the two reunite.
