Jiang Yao, the legitimate daughter of the Jiang family, is charming and smart, and she marries the ascetic and rigid Marquis of Wu'an, Pei Zheng. It was originally a contractual marriage, and he didn't want to be caught in a fire while working on the wedding night. After that, Pei Zheng even set fire to the lively and free-spirited Jiang Yao's old house, and fell into ruin step by step. Jiang Yao originally only wanted to be the salted fish princess who slept soundly every day, but she had to face the troubles in the Pei Mansion. Fortunately, she resolved them one by one with wisdom, and finally took charge of the palace. The two gradually became congenial partners from a contractual couple, and finally found a sweet love that goes both ways. Adapted from the Tomato novel "A beautiful woman becomes a stepmother, a rigid and powerful minister favors God", written by Mr. Salted Fish.
