There are so many sotries with VIllainesses that go all about "I'm gonna stop the Bad End, avoiding entirely the VIllainess from beign Exiled/Executed!" with the MC constantly going around and worrying about it, thinking of how to avoid it as each Event of the game comes, when it's clear that it'll never happpen since Chapter 1, because it's evident how everyone starts to already love the MC, and the MC would never do the crimes that lead to that in the first place.
But this time, it may be the first where I see this type of story getting CLOSER to the Bad End the more we go into it, in a realistic and completely understandable way, that also builds the characters VERY well.
The Villainess 'Attacked' the Prince, breaking their engagement herself, and rather than fix her relationship with everyone, she strengthens her dominion over them not with political power, but with fear of her raw strength. The only one they have become friends with being the 'Protagonist'.
She's truly going the Villainess Route, and I would 100% believe that the annoying and overly prideful Prince would try to go against those two, and that those two would be willing to go against the Kingdom for each other.
My respects to the author, I damn love this story!
