Cuz these guys are the best awkward couple, like dudes:
Armin: Hey Annie?
Armin: W-Would you like to uh… *blushes*
Armin: Can you be my girlfriend!? *blushing intensifies*
Annie: *blushes* What?
Armin: Will you go out with me?
Annie: *runs into girls bathroom* I don't know how to deal with this!
And then they had little blonde babies!
But seriously, these guys are to adorable! Though I do ship Annie with so many others, this gets a spot as my 2nd favorite in my Annie shipping.
I would go gay for Annie, just saying. Annie IS my waifu!
