The royals that you will try and win the hands of come from the *fictional* kingdom of Geluo. The rest of the world as you know it still exists (e.g Paris, New York ect)

A couple of things about Geluo:

#1) The legal alcohol buying age is 18. You can drink it at 15, with adult supervision, and without at 16 and 17.

#2) it is very open-minded. All sexual and gender orientations are accepted, and all genders are equal. The ruling party do not tolerate discrimination, but of course, there may be some idiots who are still racist, sexist ect ect

#3) it is a relatively small kingdom, but is well respected among the other world leaders.
