Four years ago, Jiang Shan, poisoned and seeking a cure, married Ling Fengnian, who was merely trying to appease his grandfather's demands for marriage, seeing her as an ordinary woman. Four years later, with Ling's grandfather's passing and Jiang's poison fully detoxified, Jiang Shan frequently initiates divorce proceedings. Due to a misunderstanding, Ling Fengnian agrees to divorce Jiang Shan. Post-divorce, Ling Fengnian discovers that Jiang Shan, whom he once saw as merely his appendage, is actually the country's most renowned surgeon and has a close relationship with You Ziyi, a giant in the business world. Jiang Shan excels in piano, painting, design, and martial arts. Each time she reveals her astonishing talents and identities to Ling Fengnian, he becomes increasingly curious about the wife he lived with for four years. Meanwhile, Jiang Shan gradually realizes that her feelings for Ling Fengnian have transcended those of a mere "antidote" for her poisoning.
