I also had the idea with the ruffians since their house is broken, when you let them take you, the echoes of your moans resonate throughout the slums, signalling the other slum dwellers that you are an easy mark. So if you go back, more and more ruffians show up to take advantage of you until you get a bad(not really

) ending where you become a town bicycle and they just gang bang you out in the town square in front of everyone. Maybe also have Haanja observe in horror / disappointment in the background about what you became. Or just have the bums take her too once they get the idea that the sisters are not allowed harm them in order to resist them (as the lore bit in the gallery says).
