This is some good stuff. I am looking forward to what chapter 2 has to show.
Kind of hypocritical from me, because I am normally not into netorare at all, but this sort of visceral take with the girl being the one getting cucked, and the fairly realistic reactions of the characters involved, is something I never saw before.
She's actually worse than the usual cucks in ntr but the dude was much nicer than the norm too. The age old adage holds true, you can't turn a slut into a wife.
It would be nice to see a NTR series with actual character development instead of the same rehashed scenario every chapter. No idea if that's what the author is going for here, but I can only hope.
