DEFINITELY MARVEL!!!!
Well, Marvel is my main fandom, and has been there for me for many years (I can always count on Marvel to cheer me up uwu)
But... my current fandom? I don't really have one I guess? I like a lot of things, I try not to stick too much to one fandom, if you know what I mean. But, definitely Marvel, Fire Emblem, Pokemon, BTS, and anime (Hetalia, Shokugeki no Soma, Love Live, and probably lots more..)
I'm also into books, like The Hobbit, Divergent, Hunger Games, but I'm not as attached to these like I'm attached to everything else.... I'm also into My Little Pony, which is cool, I guess :0
Currently though? I think I'm most absorbed in the Marvel fandom, especially after the release of Thor: Ragnarok. Either Marvel, anime, or BTS... Or Fire Emblem! I feel as if I'm forgetting a big fandom...
