Maybe... the jury is still out on lesbian stuff
Yes, so it'll all start rather normal, like any two people interacting but you'll get to a point of realization with each character and beyond that point you'll either be flirty with them or continue to treat them as you normally would. I've had a few people ask me about "hate" routes and routes where you can humiliate the girls and basiucally treat them like shit, there will be no such routes in this, or any of my games. It's either you love them or you talk to them as you would a normal, decent human being.
