So even if you have it disabled does it still just happen in the back ground.
Then I think this game is not for me. Thanks for saving the time.
That's... Not true. Like, at all.
Maybe I'll give the game a chance, but first I would like to know the ratio of ntr / non ntr content. It just seems to me that if you play with ntr turned off, the story will be incomplete (since there are no scenes that should be opposite to ntr scenes). And with ntr turned on, it makes no sense for me to play, because I don't have ntr fetish. Well, or option 3, to play the game like in Nukige, but I'm not particularly interested in this either.
The relationship between Rowan and Alexia isn't really the core focus of the game, so I don't think your question quite gets at what you want to know. The relationship between Rowan and Alexia is important, but it's much more a political story about a fallen hero being under the tenuous control of demons, conquering in their name despite his own desires.
And even just with the sexual content, Rowan has plenty of opportunities to sleep with other women. Is that NTR content or not? What about Alexia spying on two other characters having sex? What about the times Rowan and Alexia have a threesome?
There's NTR content in the game, sure - but focus on whether it
exists rather misses the point. The idea is that the NTR content is easy to avoid while still being an enjoyable game, and it's better to just try it (maybe skip the prologue, it's a bit misleading on this point) and see whether it lives up to that promise. Asking questions won't really clarify things further, I don't think.
