The issue isn't whether or not you can or can not fuck Olivia in the current path. The fact that you can't is part of it, but not the whole thing. The bigger issue is how the new Olivia arc was structured in the first place. It's clearly DS's attempt to add romance into the game, and that doesn't really work at all. Secondly the entire structure of the path makes no sense when you compare it to the previous Olivia path (which is still my favorite one). The only reason that Max can't fuck around with Olivia is because her mother is an obstacle. WHY is her mother an obstacle? Because everything now happens at Olivia's house! WHY does everything happen at Olivia's house? Because Max is an idiot and doesn't invite the naturist girl, who LOVES TO FUCKING SWIM and is BEST FRIENDS WITH HIS SISTER, over to the house so she can play in the pool. Those renders already exist. The sex scenes with Olivia, already exist. The scenes of her partying ALREADY exist. We can have new ones, sure, but the whole route was handled poorly.
This is Olivia, the girl who isn't shy in the least, goes for what she wants, and is a party girl! Well, now she is ashamed of her family, isn't aggressive at all, and only does stuff at her house.
The new path would be fine if it was actually logical with what we have seen in the past and know about the character. If she is nervous around her mom, then why would she bring Max there, and not do shit at HIS house? Again, it makes no fucking sense.
