Noooo, she's a contemporary woman. Self-centered, exploitive, overly controlling men always piss her off, and she is just going for a run ... okay, a wild sprint, but it's not like she's battling with dragons and giants just yet. And Nine isn't any of those things, but treating her as though she's made of glass and needs *special protection* can become a slippery slope into that bastardy sort of entitlement that the Crown Prince was showing in the last season. I think she's very sensitive toward that. It hasn't gotten over-the-top just yet, but she's wary. In that world, what modern women wouldn't be? Wanting to be treated as an autonomous and respect-worthy woman is not the same as being a man-hater.
Growing pains. Before she was weak when she first transmigrated. She was hated, used to validate pos fiance, no fighting capability, snd no influence. She's really grown since the stories start and feels that it hasn't been acknowledged. She still thinks her family disdains her, her weirdo brother is still the heir, and Nine went from being a puppy to protect to suddenly acting like a care giver. She's chafing at the lack of acknowledgement. She will get over it but will take some communication.

Has the FL personality change? I feel like she was way smarter before...why does she suddenly hate all men
And she’s even a lil bitchy to nine who has always been protective of her ( ̄へ ̄)
