Sweden/Finland

Sweden/Finland is a common pairing in Hetalia: Axis Powers, involving the characters Sweden and Finland. The pairing name is often shorted to SuFin by fans, using the first syllable of each character's name (the Su in particular from Suuweden, the Japanese pronunciation for Sweden).

Life On The Run
After Sweden grew sick of living life under the rule of Denmark, he snapped and fled the household, Finland chose to follow after him to gain freedom as well.

Though Finland was happy to be away from Denmark, he at first found the quiet and expressionless Sweden to be rather intimidating. He initially planned to run away, but after Sweden embraced him to keep him warm, figured that the taller man was probably simply hard to communicate with and not a real "threat".

Husband and Wife (?)
When Finland managed to reconnect with his friend Estonia, Sweden introduced himself and referred to Finland as his "wife". A startled Finland thought that he had to be joking, but as it turned out, Sweden was quite serious about seeing him as his "wife".

Sweden tried to get Estonia and Latvia to move in with them so that Finland would have more people to be around so he would be happy like that all the time, but could only get partial custody due to the intervention of Poland (who wouldn't let him have Lithuania).

Later on in their "married" life, Finland found a white puppy and adopted it. After a slew of bizarre names, he and Sweden made a compromise and called her Hanatamago.

Sweden also altered his spare clothing in order for Finland to have extra clothes, due to their difference in height being 12 cm.

Finland had stated that it would be nice to have children, and Sweden replied that he would "do his best". However, Finland didn't understand what Sweden was saying.

Modern Life: Being Parents
After Sealand and his king put him up for sale in 2007 to pay for the damages from a fire, Sweden, who was the only bidder, won custody of him and became his adoptive father. This is a reference to how the Swedish company The Pirate Bay(an online index of digital content of entertainment media and software created by a Swedish think-tank) attempted to buy Sealand in 2007 after harsher copyright measures in Sweden forced them to look for a base of operations elsewhere. In real life, the sale did not go through, but nevertheless in Hetalia we see that Sweden himself (who was likely alerted about Sealand during the situation with The Pirate Bay) decided to take in the boy and care for him.

In many modern day-set strips about Sealand, it is shown that Sweden has raised Sealand as a son. For example, due to Sealand being more interested in video games and TV than playing with his "papa", Sweden came up with an idea to make Sealand pay attention, by stuffing a cardboard box with "England" written on it over him and shaking him, creating what he called a "Dambolis" (in the English dub of the anime it is referred to as Cardboard-tain, a combination of cardboard and Britain). Also, the blog comic "The Nice Products that Come from Scandinavia are…" is another example of Sealand living with Sweden.

Finland also often acts as parental figure for Sealand, as seen in the 2009 Christmas Backlog comic and it's corresponding episode, Finding Santa. Sealand is distraught about not getting any gifts, and is crying on the phone to England about it. Finland is with England, and notes that Sealand must be taking another step into adulthood. It is seen later in the comic that Sealand has shown up in person with the other characters and is sitting on Finland's shoulders and being comforted.

Ladonia, like Sealand, is also treated as a child of Sweden and Finland (being Sweden's actual child and an adopted child of Finland). Though Ladonia does not call either of them papa or father, he does not object when Sealand does so while talking to him in the 2013 Halloween Event and does view Sweden as a father.

It should also be noted that America is another character who many fans consider to be an adopted child of Sweden and Finland. This in part stems from the Battle for America comic, which shows that Sweden and Finland went on a vacation to the New World to Sweden's colony of New Sweden after Sweden's part in the 30 Years War. While they were there, they were the first European nations to encounter America (and which happened at some point prior to 1655 as that is when the Netherlands kicks them out). In more modern times, America has been shown to be friends with both of them, and is especially close to Finland. One blog drawing shows Finland and America building log cabins and America states that he knows how to make log houses because Finland left the technology behind. Himaruya's note on the post explains that log houses were indispensable in early American history, and that it was the Swedish and Finnish immigrants’ parting gift. In an unfinished comic, America is shown being disheartened and upset about the Brewster Buffalo fighter jets not being very good, but then he gets a phone call from Finland gushing about how amazing the plane is and America is surprised but very grateful and feels better after the interaction. Finally, one of the main reasons that people like to think of America as viewing Sweden and Finland like parents is that in the Christmas 2010 Event, America remarks that he loves seeing families out and about, and is a bit jealous of all the kids who get presents from their dads, to which Finland responds telling America he can consider him his papa if he wants. America says he would if Finland looked older, and Finland says he'll grow a beard. America has not interacted much with Sweden but his close relationship with Finland indicates he likely is friends with Sweden as well. Additionally, historically Sweden was one of the first countries to recognize the USA before the Revolutionary War even ended, with the 1783 Treaty of Amity and Commerce. It is also seen in World Stars Chapter 194 that Sweden is one of many countries who sent indirect aid to America during the Revolutionary War.

Hetaween 2013
In the beginning of the event after Denmark has a conversation with his guest (a young girl) about their immortality, he asks the rest of the Nordics if they're lonely without wives. Sweden states he would like to be married and Finland, alarmed, asks him to clarify. It also appears that Sweden and Finland (along with Hanatamago) arrived together.

Later on in the event, Finland (whose costume is a white dress) is asked by Iceland if his costume is meant to be partner to Sweden's (who is well-dressed). Finland, blushing, says no, adding that it would "catch too much attention". He includes that he did have a three-day conversation about the costume with Sweden and then (after Iceland makes some under-the-breath comment) adds that he guesses that is strange on its own.

Fan Speculations
Some fans speculate that the relationship between Sweden and Finland has cooled down in the modern-day strips, due to Finland's independence. The two still appear to be together, though nothing has been said either way about their relationship status.

However, Sweden seems to care about Finland very much at least; almost over-caring (according to Christmas Event 2010).

Others suggest that Finland still carries a degree of Stockholm Syndrome around Sweden, and that the relationship is more one-sided than it would appear to be.

It is commonly thought that Sweden, Finland, and Sealand operate as a family unit, though it is unconfirmed if Finland has had any active part in raising Sealand beyond the strip The Creation Of Dambolis. In a more recent Christmas strip, Finland is actually depicted carrying Sealand on his shoulders, suggesting he may at least actively interact with Sealand. Finland is often pegged as the "mother" figure, which he would likely resent as much as his "wife" title in either case.

Other
Hidekaz Himaruya has said that Sweden is a homosexual. The author also said that he only acts that way towards Finland, possibly meaning that Sweden has strong feelings for him.
