With wealth, power, and status, and without inlaws or a living husband, she seems to have hit the jackpot of transmigration. Just as she begins to relish her life as a wealthy and noble lady, she discovers she's actually in a novel - as its greatest villain. Not only does she possess wealth, power, and status, but she also has three unruly children. The eldest is lovesick, the second a notorious playboy in the capital, and the youngest daughter is arrogant and domineering. She herself is destined to die soon, leading to the fall of the marquis' title and a tragic end for her children. Tang Shuyi takes a deep breath, rolls up her sleeves, and gets to work! We follow her journey as she disciplines her wayward children and navigates life as a noblewoman in ancient times, balancing wealth and leisure.
