Jiang Jin transmigrates into an old-fashioned, over-the-top 1v4 romance novel, becoming a short-lived, vicious widowed sister-in-law. Bound to a plot-correction system, she must stop the four male leads from falling for the original heroine. Right from the start, the villainous younger uncle, Xiao Luan, tries to silence her. She survives by exploiting his weakness for tears, while adopting Zuo Lin, the future emperor, to build up his affection. At the same time, she opens a medical clinic and navigates relationships with a top-ranked scholar, a general, and Prince Jing. She must also deal with her supposedly dead husband, who comes back to life, and his unattainable first love, struggling to survive amid political schemes and romantic entanglements.
