The player has the ability to unlock 'inclinations', by trying out different things and finding themselves in different situations. All NPCs have their own inclinations, which will affect their decision-making and how the game makes them act (e.g., I have only ever had Forward NPCs accept a proposition if you approach them in the showers).
The new update has also just released and has a few different things you can choose as turn-ons and turn-offs (I haven't explored them yet myself), so that's something to be looking at.
