Great approach. Your story, your rules. If you try to please everyone, sooner or later you will understand that no one likes the game. Even you. But if I express my personal opinion, the denouement of the story with Brian was a certain key moment, but in the end it was absolutely linear. It would be better to focus on the motivation of the characters than on a bunch of choices that have no effect on anything in an inevitable situation. And also to think through the options better. In case of MC's agreement, the standard netorase path occurs, but in case of refusal, the game seems to break down and although the night with Brian inevitably happened, MC begins to ignore what happened and at the same time be a part of it on the netorase path. The choice of pure netorase is saved, there is no photo, but they pop up in the conversation and MC confirms that he saw them, the netorase route with Katrin is open, the relationship between FMS and Katrin is successfully developing, but is literally ignored externally. This route looks absolutely broken and illogical, and the long lead-in from many choices on the way to it literally does not affect anything. The NTR Brian route is just one flashback and that's it. It's worth thinking better about the only NTR FMS scene that is possible without the player's consent. And to refuse unnecessary choices where it will not affect the plot, since it makes the player feel like he is being deceived.
And the mention of netorase with Mark in the scene with Michael in the pool is clearly bugged.
