ABOUT
A FANLISTING?

The fanlistings.org points out that:
"A fanlisting is a place for all fans of a particular show, movie, actor, actress, singer, etc. to come together and build the biggest listing of people from all around the world who are fans of that subject".
So... in other words, is a listing of fans about a main subject where you join with your name, e-mail adress and your country and show your... fan love? XDDD.

SUFiN TIME!
First of all, learn some basic stats about them (Credits to Hetalia Wikia).
Berwald Oxenstierna: Berwald has short, light blond hair and greenish-blue eyes, and wears glasses. Berwald was once a Viking and the "Conqueror Of The Baltic Sea", but now stands neutral in military matters and has calmed down, putting his strength into welfare. He is silent and difficult to understand, not speaking much due to the fact that he was born in a cold area. He is actually quite playful deep down, but it rarely shows through and he simply gives off an intimidating air. His hobbies include making furniture and art, and it is said that his canned Surströmming can be used as a deadly weapon. He speaks in a Tohoku accent, often translated as grunting and truncated words. Despite his silence, he apparently takes interest in arguing and debates.
Tino Väinämöinen : Tino has short blond hair and violet eyes (originally colored blue in some early illustrations). He is also often shown in the role of Santa Claus, due to the fact that Santa is claimed to live in Finnish Lapland. Tino is described as being simplistic, gentle, and honest, as well seeming rather adult-like. He's very talkative, especially around Berwald, thinking up jokes to lighten the atmosphere. He loves to think of interesting and unusual festivals that no other country could imagine, and actually likes the taste of salmiakki. He also happens to love saunas.
Their relationship: Here comes the love. Well, at the beggining, they escaped of the rule of Denmark, and even if Finland was happy to be away from him, he felt intimidated because of Sweden, so he was planning to run away, but after Berwald showed his good feelings when he tried to keep Tino warm, Finland noticed he wasn't a bad person, just he was hard to communicate. so then they decided to stay together, and so the history began.
And the love grew up when Sweden called Finland his "wife" while they had gone to visit Estonia, so that meant Berwald considered Tino someone special. And later they adopted a puppy named "Hanatamago", wich is a weird name but because of the love of Sweden, he made a compromise to call the puppy like that. And at the end Berwald adopted Sealand as a son, and if he's the father, you can consider Tino as the mother, so there you have the family.
As you see there are a lot of proofs of their relationship, besides Himaruya-sama said that Sweden is homosexual, so there you have, he's in love with Finland, and it seems that Tino feels something deeper than friendship for Berwald <3.
