>>105715169It's a Disney princess musical, they're both super traumatized after years of forced solitude and apparently don't have any other family or friends left alive. It's just sibling familial love, not romantic, but they both are kinda codependent on each other.
I expect that the sequel will see them start to branch out to their own lives, Anna will get engaged to Kristoff and Elsa will probably find a love interest too
