The game increasingly leans toward pushing players down the NTR path because, in reality, you’ll miss over 50% of the content otherwise—and the game doesn’t punish you for this choice. Meaning, everyone’s fine with it. The depraved village just turns into one big 'happy family' ^_^.
But if you play through the 'love' route—or as I call it, the 'ALL CHARACTERS BELONG ONLY TO ME' route—you run into a lot of 'problems' later on. Some seemingly minor decisions can have major consequences. For example, the fate of the queen’s daughter is unclear—what’s the best choice, and what happens to her?
Also, I still can’t figure out the correct sequence of events for the (SUCCUBUS) + CATHEDRAL storyline. Because if the MC sleeps with the Succubus, his girlfriend will start cheating on him. Plus, it’s unclear how to get ALL CHARACTERS for the MC in that same cathedral scene. It seems you have to sacrifice something, since the long-term consequences of bonding with the Succubus are unknown.
There’s also a long-standing rumor that if you perform the ritual successfully, the girlfriend might gain (POWERS—becoming a half-breed?), but even that part is unclear.
Long story short, the game heavily favors the NTR route, and it looks like that’s the better way to play (again -_-).
