Cinderella Jelsa

Elsa and Jack have been best friends since they were young, now they are in high school and Jack has a few new friends. Those new friends didn't feel the need to include Elsa in about anything, seeing as they were called The Big 4 by about everyone in the school. And on top of being excluded a lot by Jacks friends, it's getting hard for Elsa to control her feelings and something else that no one, not even her sister Anna, knows about. To add on to that, there is a school dance coming up, and during it Jack dances with a girl with no identity. Who is this girl? Will Elsa ever fit in? What is she hiding from everyone? And what about her feelings?
