Bro it's simple 100% NTR games are just mc having small small dick and others raping their girl,in harem or any other type game you have to work to get someone else girl heck even after getting on their good side you need some proof like thier lover or husband is cheating on them then only they become your lover,so basically a good story and all whereas in NTR your girl is raped mostly and who in their right mind become cock hungry sluts after getting raped this thing happen in NTR avn,that's why they are hated if you know suggest a avn game where if we ignore our lovers there would be NTR
that's netori but i explained to you right opposite of NTR and u have to do work for it like being good to girl,having treat her like princess and always being for her when she needs and even though all this she doesn't come with mc in most games ,only after they find that their partner is cheating on them,only then they love mc with whole heart,and that's the thing of story,whereas NTR is actually girls being raped and that's not sad part but that they love getting raped and then become their whore slaves as their choice is sad part of most of the NTR avn.
