Random Headcanon: The notional “Western Europe circa the 11th Century with the serial numbers filed off” world that many JRPGs take place has seen so many Chosen Ones come and go that their hierarchies of social and economic class take the status into account. That’s why the random farmgirl of the week can always get a royal audience on a moment’s notice, and why nobody’s particularly scandalised when she addresses the Princess in such familiar tones: as the Chosen of Whatever, she’s fairly high up the org chart (though obviously of lesser prestige than a landed noble of equivalent rank).
The reason for this arrangement, of course, is to remove any social obstacles to getting Chosen Ones married into a noble family as smoothly as possible. Gender is no object - even those polities that normally frown upon same gender marriage are willing to look the other way for the sake of ensuring that these overpowered meatheads are kept inside the tent pissing out rather than outside pissing in. This is also why nobody objects too strongly when the aforementioned Princess runs off with the hero to go save the world: due to a series of obscure precedents, going questing with the Chosen One technically counts as a formal courtship!
