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: "Papa And Mama"
After Sealand put himself up for auction on eBay, Sweden, who was the only bidder, won custody of him and became his adoptive father. In the modern day-set strips, he has raised Sealand as a son. It is debatable if Finland acts as the "mother", as the three have only been seen together in one strip.

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".

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.
