Su Zhaorong, a graduate student in the Department of Modern History, accidentally traveled to Su Mingyi, a concubine of the Anyuan Hou Mansion in the Jin Dynasty. The original owner was thrown into a lake by her aunt because she pretended to be her aunt's sister's engagement partner. After her rebirth, she relied on her accumulation of historical knowledge in her previous life and her ability to observe people's emotions, and she managed step by step amid the strife between concubines and concubines in the Hou Mansion and the schemes of her sisters-in-law - from being a "fake bride" who was stuffed when she married for her eldest sister, to using the "most non-threatening" attitude to resolve the dowry shortage and the main plot. After facing crises such as his mother's frame-up and provocation from outsiders, he finally found out the truth behind his death, and joined forces with the consort Pei Yanzhi, who was romantic on the surface but had a hidden edge. He uncovered twenty years of secret old cases between the Marquis and the royal family, and found his own way of survival in the house fight.
Intention: to find your own way of survival.
