Lin Wanzhao, the daughter of a declining businessman, married into the government of the town as a wedding bride. Faced with the constant troubles from her mean mother-in-law, scheming concubines, and scheming relatives, she relied on the accounting skills and strong personality taught by her mother when she was a child. She gradually took control of the power in the government from an "unpopular wedding tool"; Xiao Jingheng, the cold and taciturn Duke of Zhen, initially had a crush on her. Although he was dismissive of her, he was gradually moved by her shrewdness, determination and love. The two went from testing each other to helping each other, and jointly faced crises such as competition for family property and suppression by external forces. In the end, the heroine became the real "head of the family" of the Zhenguo Palace, and the hero also learned to let go of his indifference, and the two gained a perfect love that was evenly matched. Highlights: The female protagonist is not dependent on the male protagonist, and uses wisdom and means to fight against her opponents in the house, and the abuse of scumbags is intensive and exciting; the love line of the male and female protagonists from "superior and subordinate" to "soul mate" combines the CEO-style "sense of control" with the "reversal and exciting" of house fighting.
