So, I played the game with incest mode, only to find out that the game should not have incest. But in my opinion, the story doesn't fit well with Monica, Katie and Jenna not being related to the MC. Unless the moderator has profoundly changed the game, not just the relationships, some things don't make much sense in the story without them being related. First, I don't see any sense in the father asking the MC to cut off any contact with Monica and the girls just to get the inheritance, since Monica is just her mother's best friend and the girls are childhood friends that the MC hasn't seen in years. If so, the decision will be pretty easy, since the father had no way to predict that the MC would fall in love with them and vice versa. Another point is the hesitation the girls have, even Monica, to tell each other about their relationship with the MC, which simply would not exist if they were not related. Anyway, as I said, unless these points I mentioned only exist in the mod with incest and in the vanilla game the story is different, I don't see much point in the game without incest.
Ps.: I just found out about the game and played it all the way through. I didn't read all 1241 pages of the thread, just did a little search here and I believe this has probably been covered before, so I apologize for bringing this up again.
And I don't really care if the game doesn't have incest, I just don't understand how the story fits without it, so that's why I haven't played without the mod.
