No, towards the end of the most recent version, she confirms herself that it is true. She explains the circumstances that got her into such a situation, and the player character offers to help her get a normal job and says he'd rather not see her working like this.
He even helps her confront her dad, and I have a feeling your assistance will bare fruits(meaning she'll get a normal job) in the next update. If not, idrc as I personally am not looking at her as a potential love interest.
I'm assuming in later updates, if you help her, she does eventually stop being a prostitute, but given that's her main issue at this point, I'm not sure how KS will make her story still matter after that.(I mean the message will still matter, but what will her story and conflicts be after she stops?)
