You cared enough to bring it up.
I don't understand the mentality with some people. People love the idea of banging other girlfriends and wives, but when it's suddenly onto 'them' (it's a computer game), all hell breaks loose. The hypocrisy is real and it needs to be pointed out. The so-called anti-NTR people won't ever shut up about how they feel about the genre, EVEN if it's made clear that the game is NTR. I understand that this game wasn't labelled as such though.
I understand that one gets 'invested' in the game, but anyone raging over a plot or game tag really needs to have a healthier mindset. It shouldn't make you this upset. Really, the only criticism that is launched over it isn't about models, the rendering, or plot. It's the genre lol.
In short, go outside and get some fresh air. Nothing, video game wise, should make you this upset.
