For me it's "The Evil Lady's Hero" It's the first recarnated as a villainess type thing that I enjoyed.
I totally recommend It!! the first few chapters may be a bit annoying, but It's so good (Imo)
and "19 days" gahhhhhhhhhhhh, I LOVE THIS MANHWA SM. It's BL and it's really funny and sometimes it really serious, But it's mostly comedy. (but when it has sad parts it will really hurt. trust me) I REALLY REALLY recommend it (if your into dat ofc). BUT i still REALLY REALLY recommend it.
Are you a simp who simps over other simps who other simps, simps on other simps who simps on simps who's simping over other simps who simps on those simps? Dare... I say
