A modern nutritionist and her son both traveled through time. She became the stepmother of the Hou family's successor, and he became the dandy legitimate son that everyone disliked. Let's see how mother and son teamed up to turn the back house of the Hou family into a double standard of "fat reduction + internal volume". One became popular in the capital by relying on fat-reducing meals and quality education, while the other counterattacked from the "devil king" to "other people's children", and by the way, he turned the aloof Marquis into a love brain. In the end, both career and love are harvested, leading the women of the entire family to a broader world.
