The only thing that makes sense here is that he wanted to get the release out and had to cut content. I tend to give people the benefit of the doubt and would do the same here. If he is motivated to release a decent product, he will come back to fill in these major gaps.
This has been a problem since their first discussion when they laid out very general rules. They have had a couple of discussions since then where minor rules were added (i.e. don't screw anyone at work). Despite having those conversations, and the big reset, no rules have been discussed. Anne wants to come clean, clear the bad debts they have taken on. Seems like the most logical place to include the reader in a discussion of their rules. Even better, include the reader in choosing the rules.
This is my biggest problem with Anne and this game. Martin, and to lesser extents Dre, Ryan, the two idiots on vacation (and apparently Troy in the future), are areas where Anne's behavior is unacceptable on anything but a cheating path.
IF Anne came clean, then she would have told the MC about Martin and Ryan. Yet, if you are on a cheating path, she has another episode with Ryan via video chat. AFTER coming clean. There is no way the MC would allow those relationships to continue. So, assuming that Anne did tell him the truth during that discussion, these relationships would be over. If the reader is on a cheating path, it would be fair to assume that Anne lied to the MC during their "honesty" discussion.
The only positives I have found from the last update were the attempts to add some additional content (girl-girl), correct some errors, and make Anne a bit more likable. Unfortunately, this broke a lot of the game for most people.
For me, failing to address the rules and leaving open the Martin/Ryan content illustrate the weaknesses of the developer and this VN. I would love to see the rule discussion happen and make it a choice-driven process that allows the user to refine their chosen path. For example, the MC can specify that he wants to hear about all the sex. He can choose to participate or not. They could restrict work partners. Choose cum fetishes (inside, outside, clean-up). All the hard work has been done. The author just has to follow through! And if the reader is not on a cheating path, this would have been the time to clean up all that content.
