It can, that's the just the current background that's written. The feature of being able to adjust their backgrounds and personalities is still in experimental. All but one of the girls IIRC correctly is currently backgrounded as being very assertive, a few as outright dominant. IIRC Jo is switch, mostly dominant, Fiona is Neutral Switch, and I think its Dina that is more towards the submissive side.So like... why do all the girls have this wild and rebellious attitude? I think the game would be much more appealing if the ai could accommodate more than one personality type. Shy, timid, pietistic, optimistic, etc. etc. The girls always have this astronomically high confidence level, but incapable of being low confidence or just more chill and girly. It's all tomboy shit and wild sex. Also... the ai tends to be a control freak, always taking charge and never letting the player be the dominant one.
I feel like there would be much more appeal if the personality wasn't so static. It also makes the interactions all kinda play out in the same way. The ai shouldn't be locked to this one personality type.
Keep in mind you can also adjust the girls a bit as you play. For example, you can so something like this into the AI:
David says, "How about we do something a bit different?" (David pulls out a collar. Fiona bites her lip, realizing just how much it makes her want to feel it around her neck.)
Doing that, including both the quotations and the parenthesis, helps to force reactions more in line with the narrative you want to build. If you are one of the backers, you can preload stuff like that in the settings by adjusting the background of characters, and it maintains between loads. Non-backers have to guide it to it each time.
