After many years away from Equestria, Sunset Shimmer decides it's time to go back and get things right with Princess Celestia. Even uncertain of how the princess would react to her, Sunset goes to meet her hoping Celestia has forgiven her as well as her friends, however, what she does not expect is that things are not so simple between her and her former teacher.
Edit 12.17.2021: I've realized that the previous title was a little too long, so I changed from Who we really are? (or just another Sunset Shimmer background story) to simply Who we really are?
