You pretty much read my mind at a lot of these points.

I was thinking of there being some sort of way for the monarch to pick the spouse. I wasn't sure how that should happen, though. Maybe there being a ball that is thrown and all eligible young (wo)men are invited? Or perhaps (wo)men are selected by being brought to the home of the monarch and forced into mandatory tests of eligibility? I don't know, that was the part I was stuck at when it came to figuring out how the monarch and the peasant meet.

To be honest, the character I had in mind for this was male, so if you still want to play your female character, have at it! :) The character I had in mind for this is also pretty white, so I think it'd be hard to make the setting in Asia, but it's definitely very possible if that is what you'd want to do. I could find a way to get my white character to Asia somehow!

When I wrote the plot summary, I did have in mind maybe Medieval Europe, but I am open to what you want to do. I want you to have as much say in this RP as I do. (:
