The Middle of the Bridge

[Sister! reader insert]

Three years passed, and you and both of your sisters became close again. But when Elsa heard a voice that only she could listen to it. She responded and woke the spirits, causing the people and Arendelle in danger. So Elsa has to go to the Enchanted Forest with her sisters, Anna, you, Kristoff, and Sven.

But when Elsa heard the voice, you heard whispers saying your name all the time. Why is another voice calling you other than Elsa? It looks like you had to find that answer too.
