Another storyline might involve a friendship that develops during a global event in the Hetalia universe. Let's say there's a big international sports competition. The OC, who is a huge sports fan, teams up with Canada to support their respective countries.

It might be about Canada in the Hetalia universe going through a sudden change, like snapping.

At first, it might be a bit of a one - sided relationship where France is very enthusiastic about baby Canada.

France would be a likely candidate. France has always had a sort of motherly - like affection for Canada. He would probably be very eager to take care of baby Canada, dressing him up in cute clothes and feeding him French cuisine, like crepes.
