Eh, I just got to the scene with her in the gym where she stops spotting you mid-reps to try to blackmail you- and don't get me wrong, peeking on her wasn't a nice thing to do, (even if she encouraged it which makes the blackmail itself super scummy too), but she could have easily just spoken to you in another normal scenario and had the same effect, instead, she literally puts the MC's life in danger which is just an ultra-scum thing to do.
At that point I was just like, yeah, okay, not interested in any more content from her. Blackmailing someone for something you encouraged them to do, then putting their life in danger to enact said blackmail, was just irredeemable, imo.
