4 days late but while I am not too keen on the prostitute thing, she goes into it for money and dealing with a deadbeat dad, not because she want's to just enjoy sex. I mean fucked up truth is, that is probably the fastest way for a teen girl to make enough money to survive off. I don't mean like OF girls that start right at 18 because they want quick, but she actually needed it to survive before MC and his sister come along.
I am in no way saying that I like main LI's being prostitutes in a harem game but it seems to be going the route of saving her and getting her out of that life, whether as a friend or lover. Which would probably make her 100% loyal... or you can ignore her I guess. But even if I decide not to pursue her as a LI, I will as a friend. I think if done right (we will see this update hopefully) we could get a good mature story about saving her from a shit life as a prostitute. More that than any form of NTR.
But I like Ayase and Miharu (I think think that's her name) more so maybe I am not as upset since I am not as invested atm.
