Sorry but "proper ntr" is antonym to "female protag" (unless they watch helplessly how their husband being stolen - I've yet to see such plot tbh). They are not compatible. Key features of ntr is sense of loss, betrayal and jealousy - and that all absent from female POW. What you like to see is called "reverse ntr" - the subgenre where protagonist is being stolen/seduced from their loved one. Unfortunately, this genre is very often wrongly labeled as just NTR (mostly in case of female protagonists though) - which creates misconceptions about the whole genre. "Reverse ntr" genre with female protagonists is closer to standart corruption/sluttyfication fetish rather than ntr fetish.
By proper ntr i mean game that focues on ntr rather then just banging whomever.
Fundamentally it is not right to call any NTR a proper ntr because people like different things about NTR, in short some wanna steal others wants things stolen from them and then the rest just wanna see the heist.
I visit various sites and i have never seen "reverse ntr" tag. VNDB doesn't have it for one. So i think it falls pretty deep into NTR category.
NTR = cuckhold. That's it, nothing else. While it's been split into 3 different sub groups ( Netorare, Netori, Netorase ), overall, as long as cuckholding takes place ( no matter it's form ) it's NTR, that simple.
To fit Netorare, the
only requirements is: 1: One person in stolen\taken away ( i.e; falls in love with someone else through cheating\coercion, etc ), 2: The other person becomes aware of this at some point ( usually at the end ), [
or the other person is at least introduced to the story]
Netori - Always the perspective of the one taking away, and not of the other two's perspective.
Netorase - From any of the 3 perspectives ( taker, taken, taken-from ), the key is that it's consensual.
Edit: Text in '[]', followed by next segment of text:
So:
Non consensual perspective of anyone in the couple? Netorare.
Non consensual perspective of the one stealing? Netori
Consensual cuckhold? Netorase.
Really is that simple.
P.S.: I wonder why Alice Soft didn't try to sell the game in steam? Considering there isn't any lolies and there are lot of 18+ games in steam nowadays - I don't see a problem.
Because Steam fucked them over once. They have no desire of going through all of this again as it potentionally harms the brand.
