The daughter of a real wealthy family was unable to fulfill her contract for some reason, and the heroine, as her half-sister, was pushed out by her father to "marry on her behalf". Everyone thought she was a soft persimmon who could be manipulated by others, including the domineering male protagonist. But the heroine is actually a dormant business genius. She takes advantage of the boss's "three-month divorce" window period and borrows his resources and connections (information gap) to pave the way for her own business empire. Every time the male protagonist dislikes her and wants to humiliate her, he unknowingly hands her the knife to bring him down.
