K... but Maia might be portrayed as an autonomous agent with personal convictions and a sense of her surroundings. She might not want to break up someone's relation. That's her action. I don't see this in any way as assuming monogamy, but even if it was, society is overwhelmingly monogamous. Yes people like to sleep around, but nobody want's their partner to do so. Society overwhelming favors treating people how they want to be treated, and while people object to monogamy for the political sound-bite almost nobody actually behaves that way. So even if it was assumed, it would be somewhat justified. It's further perfectly okay to write characters who uphold that standard and aren't simply fantasy husks that are shaped at the player's discretion.
