The person who replied before you put it in a better way. I guess I'm not so much into humiliation of the cuck on it's own, because sexually, Sophie was as corrupt as can be, and now it's moral corruption.Surely you must be joking.
Has she sabotaged Felix work so he has to work overtime? guilt tricked him to think he is responsible for everything?
Has she humiliated him in front of others? (directly not whatever some coworkers think of her attire, on her own, like in front of class "Oh Felix you can't get it up again?"
She could also desire to corrupt others like Danielle or better Jonah.
This route is nearing end, devs are probably tying ends that didn't play part in this route but are certainly there (like Zach and Brooks past, Jonah and Danielle). I expect foreshadowing for future routes.
I'll still stand by what I said, Azienda has a problem with dragging stuff out, including writing. It's good advice, in writing to only include the stuff that has a point (so filler language should be expunged).
I'll still support them, this game, and their future projects. For me though, this game has lost sexual tension. Each to their own.
