Jiang Ni and Bo Yanhuai have been married for three years, pouring her heart into nurturing their small home, yet her husband stubbornly insists on taking in Lin Shuan, the widow of an old friend, to live with them, favoring her in every way and continually ignoring Jiang Ni's grievances. Heartbroken and disillusioned, Jiang lets go of her emotions, deeply cultivating the art of ancient book restoration and making a wide circle of knowledgeable mentors and supportive friends. She gradually investigates and uncovers the truth of Lin deliberately manufacturing conflicts and concealing inside information on multiple fronts, collects complete evidence to defend her rights reasonably, and smoothly dissolves the marital relationship. At the same time, she clarifies the dispute with her biological family elders who encroached upon the assets left behind by her mother, takes back everything that rightfully belongs to her, completely shakes off her depressing past, and opens up a new, independent, and poised life relying on her unique skill.
