A modern AU about the evolution of Elsa's love for Anna growing up and how it grew from something plantonic and sisterly into something ritcher and more romantic in feeling. Or the revolation that it had always, sort of, kind of, been one in the same type of love. And that she had never really needed to worry about it being wrong because, where Anna was involved, nothing could be.

After the Great Thaw, Elsa and Anna recover from their harrowing experience. They resume their duties as Queen and Princess until a visitor from a faraway land turns their lives over, sideways, and under. Through unexpected misunderstandings, a war and a trip to the gates of hell, they learn about themselves, each other and the wonders of True Love. (Elsanna) (COMPLETE)

Elsa still isn't entirely sure how Anna got it in her mind that they should be friends with benefits, but a few weeks and one set of unexpectedly romantic feelings in, their relationship will never be the same. Based off a set of posts by tumblr user fixeruppr.
