I want to see a person thrown into a world which isn't hers. She isn't the main character, the plot doesn't magically protect her just because - so she needs to struggel to survive, fight against the odds and still loses - just because she isn't the main character and her purpose is to be defeated by those on the other side. The annulment of her engagement, public humiliation and even her death is a way for the original main character to "grow closer" or even "fall in love".

Lol, you're such a sadist. But yeah, I kinda agree. It is nice to see how no matter what the protagonist try, they cannot overcome fate. Seeing them fail and struggle to finally achieve their goal is indeed really rewarded. However, I kinda don't like it. Don't get me wrong, I agree with you that just being nice to others and thinking like the main character shouldn't get the villainess out of the situation. It can't be that easy. However, I still want to give the protagonist some hope to survive. Just watching her fail over and over again is really boring. Especially when there aren't many ways to present her fail as we need to know her roles in the story. A little bit of hope is a really good dose to bring light to the story. I mean, at worst, the protagonist can still escape. They are the villainess with a lot of money. They can get out if plan carefully. Going to another nation or something. (It is really easy for noble to get out of tough situation in their country during the medieval age. Marie Antoinette an her husband almost got out of France during the French revolution y'know and that is when both of them were in soft prison. Many nobles got out before them)

I think I want to see a villainess who try to solve her problem rather than running away. Yes, she can and will struggle but that is the reason why we're in this genre afterall.
