All of the above nations with the exception from Iceland are considered to be amongst the richest countries in the world, they are also small and might not have all that much saying in the big questions of politics.

So these nations end up hanging out like some sort of high class club.
Enter Iceland who's a good friend to one or more of them but doesn't feel that he fits in, mainly due to being poorer and not having the same kind of lifestyle.

Pairings, if any, is up to the author.

Bonus 1: Some mention about Norway being just as rich as the others but having a more modest lifestyle.
Bonus 2: Smut. I need more smut with any of these characters.
