To me it's not really like the typical reincarnated story because in most reincarnated stories the "villain" either doesn't have a reason to be a villain or is not really a villain at all. Meaning that a certain plot point made them a villain so if you change that plot point which could be saving a character or something then they wouldn't be a villain right! The difference with this though is that the chade family in this story is the necessary evil meaning they do all the king's and kingdoms dirty work but roselia is refusing to see or accept that and is disillusioned with her reality. Sure some of the other nobles hate the chade family but this is only because they can't be corrupt with them there. This chapter shows exactly why they never told her about anything, she needs to get a grip and accept that this is what it is.
roselia is acting dumb and delusional
she thinks she can change the flow of the story by changing few plots here and there
but act panic and anger/ shock when the real Ein and Husband shows their true self
she didn't even get grip of reality as those two are meant to be like that
but ohh well that do you expect of a typical reincarnated story like this
