i don’t think they ever showed her as super smart, she’s been characterised as listless, and just going with the flow, and she even said she was never really that smart, but was just talented in noblemen’s hobbies. i think she made good moves when he’s not around, but is just really bad at communication with him.
on the other hand, i hate this man’s fucking guts, tryna condition her into obedience. still SA since there’s such a huge power imbalance and a literal chain.

This story is becoming repetitive and drawn out. Exactly what was the point of showing how strong and smart she was and then turn her into the exact opposite. She is not even that upset that he is a stalker and has imprisoned her in every aspect of their marriage. I've never had to read about a female lead being so dickmatized in a non hentai story.
