I disagree that it came out of nowhere. There were some hints at least in Book 4, they were just subtle (especially compared to previous relationships in this show). Korra responded only to Asami's letters, she blushed when Asami noticed her new hairdo, stuff like that.
It isn't great writing or anything, but there is enough, even if very little, material for me to accept it.
It's still a gay/bi relationship for the sake of it though, which is my problem with it.
