“Your Majesty, please don’t kill me again.” What's a character/s is mischaracterize and/or hated on for no reason in your opinion?

I'll start first and say that Rupert from Your Majesty, Please Don't Kill Me Again.

This could honestly be said for both of them as Laliette is SO mischaracterized that it's genuinely insane. BUT, people hate on Rupert so much and it genuinely makes me think they just skipped over his ENTIRE backstory. Like, did you even read the story??? Anyway, I could go on and on about them since this is by far my favorite manhwa..
