Lin Wanqing, the concubine of the Zhenguo Duke's mansion, had her biological mother die young and was treated harshly by her legitimate mother, the Zhao family. Even her hairpin gift was withheld. In order to cling to the rich and powerful, Zhao actually wanted to marry her to the tyrannical Anlehou to fill a house. Lin Wanqing was unwilling to accept her fate, and used her wisdom to expose Zhao's conspiracy and reject the evil marriage. By chance, she rescued Xiao Jingyuan, the Marquis of Zhenbei, who was being plotted against, and the two gradually fell in love. After marrying into the Hou Mansion, facing the jealousy of her sister Lin Ruowei, the secret temptation of her mother-in-law Li, and the contempt and neglect of the old slaves in the mansion, Lin Wanqing worked step by step to seize the power of the housekeeper, punish the evil slaves, and protect his cronies. Under the protection of Xiao Jingyuan, he found out the truth about the death of his biological mother and punished his enemies. From a concubine who allowed others to bully her, she transformed into a mistress of the Hou Mansion who was able to run the family and protect herself. Together with Xiao Jingyuan, she created a story of a stable house and deep love.
