There is definitely more vanilla content in the game. Like 65% to 35%.
And actually, I'm doing this(both paths thing) because that's the kind of games I like, too. For me, only vanilla or only NTR doesn't make sense.
For example:
There's no other guys in the game but you, or if there are, they are ignoring all the beautiful girls, all the girls are chasing only you like they're bewitched and eventually you get them all no matter what. It doesn't even matter how you treat them, they'll keep running after you. Are we in a fairy tale or something? I know it's not real life but still BORING!
or
You have an MC who lets all the girls he has get easily fucked by other guys, LI's cheating on him with no second thought. Maybe he sighs a little but then he doesn't give a shit. Then these girls become just hollow simple whores. No real emotions, no real bounds... you're no better than a simple cuck. Where are the feelings? Meaningless...
To me, there's no point in having Vanilla without any risk factor or side things. There must be other things in the story so that the MC fights for his girls. Wrong choices must have consequences but at the same time, by making the right choices you can still play the way you want. You can have any girl, other men can't even touch them, but it shouldn't be that linear.
Same goes for the NTR side. The girls in the game shouldn't be simple beings who jump into the laps of other guys at the slightest opportunity. They should be loyal to the MC, but the choices made in the game should impact what happens next.
