Sweden may have a...tense relationship with Finland, and be in a relationship that is not entirely consensual on his part with Sister Finland, but there is one from the Suomi family that he likes: Finland’s cousin, Åland.
There was a time when the whole Finland family lived with Sweden, but when he lost the war to Denmark and Russia, he had to give up Finland to Russia and Åland moved with him.
When Finland became his own country, he made Åland move in with him, despite Åland’s protests. He always liked Sweden better to a point where he talked Swedish. He wanted to move back in with Sweden, and Sweden wanted him back, but Finland said no.
Åland tried a few times to go back to Sweden, but Finland kept getting between them, but ended up at least letting Åland have his own house (autonomous region). To show whom his heart really belonged to, Åland chose a flag that resembled Sweden’s more than Finland’s.
Such is the love story of Sweden and Åland.
Heh, people kept asking me to do something with Åland, and most suggested that he would be an adopted child of Sweden and Finland, but as you can see, that wasn't what sprung to mind when I read about the islands. ;)
So I tried to make Åland look like he was related to Finland, but had a personlity closer to Sweden.
