Then I will clarify a few points. Route 2 is a new passage of the game, or is it a continuation of the game and the events take place there after the girls were "danced" by random dudes, with the help of mс? (I looked at the gallery and most of the content there is either route 1 or ntr, and on route 2 I counted 8-9 events).Yeah, to be fair a few comments straight up said incorrect things about how events unfold. To be completely, 110% clear: the game is divided in 2 Routes. You HAVE to play one after the other, as it's a full story divided in those two. During the 1st Route - which is divided in 5 Chapters - during the 3rd Chapter the Main Character will help another man fuck one of the game's six girls, since he didn't have any interest in her yet, because he gets off of causing chaos. It honestly depends on whether you can accept that part, to be honest: it's not NTR, and it's not even Netorase since the main character, at that point, didn't care one bit for that girl. I see some in this thread disliked that someone aside from the MC gets to fuck her, so it really does depend on your personal thoughts on the matter.
That's it. If you never lose during the 2nd Route, no one but you gets to fuck the girls. Meanwhile, in the 1st Route, that's the only instance where you see someone else have sex, and even then, it's not with a girl the protagonist had any interested in yet. There is no forced NTR in this game, and even then what little there is of NTR is completely optional if you lose certain fights, and doesn't exist for anything but as a set of extra scenes you can see if you're interested in them.
Hope this helped!
