I am wondering the same thing. It isn't a complaint as such, but just wondering if there is a pay off somewhere for being "good" (depending on your point of view). Not corrupting anyone and choosing what a stereotypical hero-archetype would choose at every decision.
Related to this, can you actually advance Emily's story at all without corrupting her? Once she starts asking you to sleep in her bed, at some point the sexual adventures take off and she always starts with oral sex which corrupts her. The same situation happens with Frisha, her story progresses (automatically) with oral sex which in turn pushes her corruption up. Am I correct to assume that these two ladies cannot progress further without corruption and ergo Emily's house-quest cannot proceed without it?
Great game by the way, as mentioned by multiple people before, there is really something to say about the possibility to replay the game and still find other routes/ different scenes/ conversations, etc. If there is a possibility to help in terms of English writing (grammar correcting, word correcting, etc.) I'd gladly put in suggestions/corrections if there is a place to do so.
