Why does Tang Ye often play Keyu, the first vase for entertainment?

Tang Ye, the first vase in the entertainment circle, often hits Ke Yu because of misunderstanding. In The First Vase of Internal Entertainment, Ke Yu is a character in the novel. She is very beautiful, and has won the favor of big directors in the past six years, because her beauty has been exposed to a lot of black powder in the entertainment circle, and her boyfriend Tang Ye often misunderstood her, which led to Ke Yu's frequent innocent violence by him.
