Her plot hole is she's not thinking. The orange haired girl thinks that Ras got rid of the useful consorts in the harem period. She didn't try to think that those consorts were somewhat controlling the empire through the powers behind them. Plus Ras didn't just didn't get rid of that power imbalance that the other consorts hold she substituted them with other alternatives that makes it so that the empire can stand alone without relying on those other powers. Obviously she's gonna do something stupid in the later chapters that will make Ras get rid of her. She shouda had just kept quiet that way she'll still be able to observe the emperor she obsess over so much.
How can he run a dukedom with that mindset?
Oh rumors says she a bitch, a whore
Him: believes it without verifying
Oh rumors said that this business is profitable.
Him: Invests in the said business without verifying anything?
He kinda dumb. If he judges things based on what he hears then he would not make a very good business man. He was also thinking that she was a spy from the start, why didn't it bother him that she might tell on the contract marriage he made to the emperor. The story is not very well thought out. Just another of them stories pulled from the romance gutter thinking the readers will eat it up. Cause WE JUST LOVE TOXIC MLS.
