okay MC is so likeable i-
she's very very cunning, and is aware of throwing away face and at times even gave ME second hand embarrassment for the mouvement of her plans, and i think that's super admirable of her as well as a very strong and risky turn the author wrote in for the character! she doesn't necessarily do what's "morally good" but she's definitely not immoral, and she's a super good judgement of character. She also specifically mentions all possibilities of one's character or their motives, when normally, i feel like plots tend to simply state something's wrong with someone but since they don't elaborate what the character thinks about that, which makes them look dense.
and all the other characters are also well-developed, even the supporting cast, which i think is amazing/difficult given that normally, they don't have a lot of screentime.
and what i think is really interesting, is that the author brings up her past life a lot as well, making it very clear that she's still her past personality, rather than sorta changing characters depending on their positions/lives in a new world. she's also not like a doctor/super smart student/someone who spent a lot of time studying a specific career like most isekai MCs are (not like there's anything wrong with that, those characters are kickass too!!), but rather, uses common knowledge of things in a world where magic tends to have others overlook more "normal" or human things, which I think is super cool, and makes her more relatable. it also shows how smart she is, and how she tends to see the big picture.
also i think there are a lOT of funny moments, and i really like the dynamic between the Fl and ML, though, i'm not too far ahead (only on ch 31!) so i actually haven't seen too much between them. but the ML is also very independent, and isn't unreasonably cold to the FL like most reincarnated villainess mangas are, as he seems to have a much more complex and difficult relationship past that with her past "not liking her because of her relationship with the other FL".
overall, i'd totally suggest reading this!! idk, maybe i'm just a sucker for smart villainess MCs tho.
