Gu Zhaozhao, the legitimate daughter of Ningyuan Houfu, had her mother killed by her aunt. She pretended to be stupid for ten years to avoid trouble, but was used as a pawn by the Houfu to marry Shen Yan, a cold-faced monk from Zhenbei Houfu. After the marriage, Gu Zhaozhao used his hidden edge to expose the conspiracy of his aunt and concubine, and gradually took control of the internal affairs of the Hou Mansion. At the same time, he and Shen Yan went from using each other to knowing each other and falling in love, and finally protected the story of family and love. The highlights are the reversal of the silly girl pretending to be a pig and eating the tiger, the thrill of a precise slap in the face during a house fight, and the pure love interaction of "the cold-faced monk is tamed by the sweet lady" in Marriage First, Love Later.
