|To put things simply, the pairing of Denmark and Canada is very cute and cracky and I pretty much try to convert fans of either character to consider this pairing. The following points below are musings as to why I like it.|
1. Although they have an unclear history together, I consider that Denmark may have met Canada along with Norway and Iceland (maybe even Sweden and Finland) during the 11th century. It helps that Canada and Denmark are still committed to protecting the arctic together even with the Hans Island dispute.
2. Canada can be pair-able with almost any nation and I consider Denmark to be a good challenge to rationalize a relationship with.
3. Denmark has varying true government and historical relationships with Canada's family that I think are cute. If Dani and Mattie were married, I see America to be the equally crazy if not more boisterous brother-in-law, England as the father-in-law that has a problem with him, and France to be the happy father-in-law that is all too supportive of Canada and Denmark's relationship.
When it comes to pairing rivalries, Netherlands and Prussia are the biggest threat to Denmark. Netherlands has more of an advantage due to the close relationship after WWII and Prussia has his "ensemble darkhorse" awesomeness. Even so, Denmark is awesome in his own right by having a mix of Russia's axcrazy/stepford smiler tendencies, an odd mix of Prussia and Netherland's looks and the similar attitudes of the other two-thirds of the awesome trio (America and Prussia).
Anyway I think too much. XD
