Shen Miaoyi, a maid from a lower-class family, was originally the most inconspicuous and rough maid in the Hou family, but she possesses extremely keen observation and insight into people's hearts. Unwilling to become a victim of the power game, she took advantage of the opportunity of the prince's legitimate son to choose a servant, and used the ultimate strategy of "predicting people's hearts" to be promoted from a rough maid to a personal maid. In the Hou Men's deep house, she defeated the treacherous mistress, uncovered the conspiracy of the hypocritical sister-in-law, and quelled the power struggle between the sisters. When the court was in turmoil, she acted as an "invisible counselor" to help Pei Jingzhi, the eldest son of a concubine who had been exiled by the family, return to the peak of power. The two used each other to the extreme in the intrigue. In the end, Shen Miaoyi took back the deed of her life and became a first-class marquise who listens to politics behind the curtain.
