The thing with the Maya/Josie scene is that it only triggers if the MC in a relationship with the two of them. Hence even that scene only exists in a version where the two cannot stop expressing their lust for the MC. If you do not pursue them, there is nothing in the game to indicate that they have any affection to each other, yet that end scene that asks for the player to accept this problem exists in itself.I thought there were sex scenes with Josy and Maya (that didn’t include the mc).
Of course they discuss the mc during those scenes, but that’s because this isn’t just a novel, it’s a game, where talking about the Mc elicits thoughts from the players that they themselves are being spoken about, so stroking the mc’s ego will result in stroking the players ego which will result in the player enjoying the game.
Also, while Maya does seem very excited about her new sexual relationship with the MC, there’s nothing surprising about that. She thought she was gay and now she’s finding out she’s bi, she loves Josy but the excitement of a new sexual relationship unfortunately often trumps that of an exisiting one.
While it may be ironic that the fathers efforts to keep Josy and Maya apart have resulted in Maya finding the Mc, that doesn’t diminish Maya’s love for Josy, the only options so far are for Maya and Josy to stay as a couple or for them to include the mc, so it just leads to another relationship that the father would have issues with.
An important point here is the father shouldn’t try to control his adult daughter’s relationships. That’s not to say that parents shouldn’t dispense advice to their adult children, but they shouldn’t control them.
As I don't know how to multi-quote, I'll tie another comment to this as well. I would agree that the game has a lot of layered characters. For me, you can make that argument about Sage, Isabella, Quinn, Jill and even the teachers. This doesn't necessarily mean that they were all well and badly told stories, just that they have multiple elements to their characters. This does not apply to Josie and Maya who are extremely superficial characters. The issue is that their whole story arc is tied to this 'forbidden' love they have for each other. Except in the reality presented by the game, it doesn't exist at all. Both of them are utterly driven by how much they want to have sex with the MC. The game constantly the stakes of their story and instead of addressing that despite the criticism, the author just doubles down on it.
Also, I want to repeat this, what diminishes their love for each other is that it does not exist in the game. This goes beyond PDA, I could accept them not showing that, but rather in every scene where they have an opportunity to show how much they much they mean to each other, the game makes it how much more each of them values the MC over each other.
