@Hiraelle And when I say "it would take less to guess they'd fall in love if one of them was a guy", just look at Korra's first relationship : it's obvious as shit something will happen between them (guy whom I forgot the name, not Asami obviously) since the first time they met
Well at least that was obvious to me, cause we're used at having that kind of love when it's between two people of different gender that we know that this will happen, except if the show was labeled "queer"
