Lin Wan, a modern office drone trapped in the 996 grind and cutthroat workplace competition, suddenly dies and transmigrates into an old-fashioned family intrigue novel. She becomes Shen Qingyuan, the marquis’s legal wife, who is thirty-eight and destined for a tragic end. Shen Qingyuan has been married into the Yongning Marquis’s household for fifteen years and has borne two sons and a daughter, yet her selfish, cold-hearted husband dotes on his concubine. All the children are badly brought up, and in the end she is drained of her dowry and dies of illness in a cold courtyard. At first, Lin Wan plans to lie flat and enjoy a peaceful retirement. But the marquis’s household is in constant chaos: her selfish, biased husband and scheming concubine make life miserable, while her three troublesome teenage children are forever getting into trouble. She has no choice but to abandon her plans to lie flat. Using modern workplace management methods and her knowledge of the original plot, she takes down the concubine, gets the cold-hearted marquis under control, and sets about reforming her three unconventional children, uncovering their hidden talents along the way.
Lin Wan then plans carefully at every turn, safeguards her entire substantial dowry, successfully divorces her husband, and establishes a household in her own name. Applying modern business strategies, she launches chains of rouge shops, restaurants, and cosmetics stores, becoming the richest woman in the capital in just two years.
Meanwhile, two excellent men show interest in her, but Lin Wan turns them both down. She’s had enough of romance after being caught up in it in her previous life. This time, she just wants to focus on lying flat and enjoying her retirement...
