I Fell Madly in Love with Her, but While We Were Dating, I Discovered Her Secret

I Want the Kind of Ancient Novel Where the Heroine Seduces the Hero for Glory and Wealth.

I want to read a book similar to "Begonia is drunk in spring: She is crazy about being in the outer room". The female protagonist is extremely good-looking and then she thinks she is very scheming. In fact, she has been manipulated by the male protagonist all the time, UUs, please beg me.
