But in the end he's right. There are tons of characters out there who lie, who never come clean across the MC, yet people still love them because "she's a badass but I'll show her what a real man is". Here we have that kind of character and, in the very last moment, when we were thinking she'll be ours, she drops the Josy bomb and prefers to stay with her instead of coming to us. And of course the way our MC reacts to the news, storming out of a potential threesome (that's how your regular lewd game would have handled that situation) add to that bitter feeling. Then people take all those feelings and try to give a rational reason for their anger, and Maya is the common escape as she's the one who had the most screen time and therefore the most chances to make mistakes
