Sorry to nerd out but tbf an escort isn't necessarily a prostitute. They are entertaining rich ppl basically and well serve as a "human trophy" so to speak obv some are pressured into selling their bodies for numerous reasons but prostitutes aren't the same thing. But yeah that fate is always cruel and harsh being made to entertain ppl at that level who see you as a prop is sickening
Honestly, judging by jinu's act to these escort (early story) and the fact that they are gonna be 'introduced' as organization's traitors, make their fate kinda set in stone imo. Also usually sell bodies make higher pay, right? During escaping period, There's no way her interest is not getting higher.
Even if she refuses it's gonna be futile. This time unlike before, everyone gonna turn blind eye with every discriminations and abused they're gonna facing, including from customer. Ain't no way they risk their lives for sake of someone who had the guts for leaving them in this hellhole. Imo it's still gonna be forced prostitution.
Sorry for being pessimistic :(

So both of them are forced to be prostitutes, give all money to organization (for the guy case). No freedom, no will, living similar to livestock for the rest of their lives...
It's indeed worse fate than dying.
