This is very ominously over-the-top, but it's nice. The pacing's alright, the characters seem to have enough individual personality, and the FL isn't a complete doormat (although she's also not directly confrontational, so it seems others will need to sct against her first for the plot to move).
What tickles me the most about this, though, is that this is the exact plot an "orignal FL" would have in one of those "reincarnated as a villainess in an otome game" mangas. Everything is just so perfectly coincidental lolol
