This.... is complicated. I also hate it, because it's stupid people doing stupid things, and NTR. And yet it's also pretty damn good quality, and there are a bunch of feels. Too bad I don't care, because it's, as mentioned, all about tragedy, nearly all of which is brought about by terrible decisions. The problem with me just giving it a 1 rating and moving on is that all the stupid decisions are at least internally consistent, with literally all the problems originating from one major manipulator who can see the future making use of everyone's lack of communication. Had that one manipulator not showed up, there would've been drama but things would've worked out ok. Instead, it turned into a massive mess with an absolutely silly bodycount.
So yeah, I can see the quality being rated as being somewhat high, but I really don't care because it's based on trash premises. Honestly if you're in the mood for melodrama and stupid people making terrible decisions and life sucking, then give it a shot, because you'll probably enjoy it. As mentioned, the quality is 'good'.
But if you don't like NTR and such, then just avoid it entirely. Not even worth starting the first few chapters because it only goes downhilll from there. Theoretically I might check out the last few chapters once it's completed to see if I read it, but frankly no way until then.
