Just my $0.02 re:the end scene:
The way I see it, there's only really two ways of dealing with that scene that respect Audrey's character and keep the players happy. Either Audrey is only there as audience, or she already knows that it's the MC before doing anything (or maybe both). Victoria must have had some inkling that Audrey liked the MC before then otherwise she wouldn't have set the entire thing up, so maybe Victoria saying something like "[MC]'s blind and deaf, he'd never know if you didn't tell him, this is your chance to fulfill your fantasy" before they do anything or just play the scene as is but with Victoria being the one doing the fucking (with the added benefit of not literally raping the MC (as someone else pointed out, MC had consented to being with Victoria, not anyone else, sex without consent is rape)).
Aside from that, a good start. Though as others have pointed out, MC does fall a little into the "emotionless brooding MC" stereotype that seems to be prevalent. Looking forward to the next version and the rewrite of the last scene.
