First of all, the story is bad, abrupt and illogical, better to say that there is no story, but it's a sandbox, so I didn't really expect Lord of the Rings from it, I admit sometimes it's even funny, so - moving on.
Grinding, too much grinding even for sandbox, you literally work your ass of figuratively speaking and.... And it leads us to the main problem - Point System. This system apparently doesn't work correct or should I say doesn't work at all at some moments. Through this mechanics you gather points with girls to keep them from the other dude and a gang, but in the end you get slapped in the face with the fact that other dudes still have their way with your family members.
I know it sounds weird but The point system is pointless heheh.
So, for those who is seeking for the answer - No, NTR is not. I repeat - it is NOT avoidable, red code)) Means you can't prevent it from happening, you have been warned.
No, seriously, it looks like Dev in this game for some reason decided to go full rampage on vanilla players, he even put a note in description that this type of content is optional, which is a blatant lie, yeah))
Now, the conclusion, why so low rating - if we forget for a second about the Dev's trick, I still would have given it a few points, but... the infamous point system. How it was supposed to work (my perspective): depending on your choices/actions this mechanics rewards you in the end correspondingly. So, if you like voyeur/ntr stuff, you do the needed grinding and you get this type of content, the same is with vanilla, you choose corresponding choices and get vanilla. But in reality you are only rewarded on ntr-route, because on vanilla-route even if you literally work your ass off (and waste hell of a time) the game still throws it at your face, deal with it.
Maximum you can do is to skip those scenes sometimes, but it still happens which you can guess from further dialogues, for me it is better to see ntr than being left in suspense, wondering what they have been doing there with that dude... - of course, of course they have been playing chess)))
And for some scenes you don't need any guessing, the game tells you this straight.
Anyway, in few words - in my case there is a lot of unrewarding grinding. Hence low rate.
Peace!
