@zloquanx prostitute make a living, that girl.. It's more like she had a relationship? At least i think that's what she thought in the beggining.
I remember the chapter when she broke up with that guy, she did say that their relationship became sex only and she wasn't interested by this anymore, meaning it wasn't quite like that at first.
I think she realized too late what was the actual situation and.. She went for it in the end.
She did this with only one dude it seems.
People make mistakes, and at the end of the day, people are people. Prostitute or not, it's someone. Someone that can be clever, funny and like everyone else,
be loved.
