The eldest daughter Su Man, who was raised in the countryside, returns to Kyoto. Everyone laughs at her for being a bumpkin. The stepmother and stepsisters joined forces to plot, but they didn't know that she was already a professor, a medical genius, a guqin successor, and a top designer at Kyoto University. They didn't expect that the heir to the Huo family was actually her obedient "fat apprentice" when she was a child. When she fully revealed her identity, the whole of Kyoto trembled for her.
