I haven't played chapter 2 yet, but I want to discuss some things. At the end of Chapter 1, there was that one scene away from the MC's perspective.
But you had intentions of doing some mystery NTR for this title based on the OP. Mystery NTR is by far the hardest one to write among NTR subtypes, especially if you take a non-comical approach and keep things more or less grounded. You need to withhold information to the players but still somehow make it hot enough to edged them along and build up tension without making turning the MC into a literal retard with zero situational awareness.
But even perfectly executed mystery NTR tends to have an opportunity cost. Many players do want to watch the scenes and corruption arc in detail at some point. When you shifted out of MC perspective in chap 1, I was wondering what your plan was in structuring the game. Because the players are already getting information that the MC doesn't have. Will the mystery only be kept in regards to the main female characters? And how will you handle the tricky part of making it fappable? A lot of mystery NTR uses tropes like girl having sex while on phone, behind curtains, under tables, or onlyfans type account with a censor/mask. Those are all hot, but it does sometimes strain the plausibility of the situation and often puts into question the IQ of the MC.
One way you can get around this is by using a recollection room/gallery thing. The players could decide to watch (or not) what was happening away from the MC's perspective. This is kind of a best of both worlds type of deal, but in practice, it will probably be a crutch. You won't feel the need to make the mystery side of things fappable since you are allowing players to view the full thing at their leisure. Another method is to only release the full perspective after you finish the male MC perspective. That has its own pros and cons.
Anyways, I don't know what style you will go with nor do I have any intention of suggesting a path. That's all up to you. But in case you haven't, you might want to play Girlfriend Tapes. It was one of the best written mystery NTR that really kept things strictly MC POV.
