OK, now that I have finished the current build, some thoughts about "the betrayal". Even though I am not a huge Lydia fan, I am not sure she was behind the blackmail. I am pretty sure she knew about the app and it being on the school server(maybe even funded it being built) but the "retention program" was a shock to her. She acted shocked when she was told about it in the shower, asked for some time, then she went to try and find out about this part of the program that she was not privy to before this. I think she just was in on the idea of the app due to her voyeristic nature but had no idea that someone else had put in more malicious code. Of course, our protagonist thinks she is behind it all, when really she was just behind the "normal" part of the app. As much as I don't really dig her as a permanent LI for my MC, I don't think she is evil, just an odd bird. That said, I am into watersports, so no kink shaming. Of course, blackmail is not a kink, it is non-consensual and except for non-con roleplay, that is not a kink, it is a crime(yes, I know that some kinks are considered crimes in different parts of the world but non-con should always be a crime, while kinks should not).
