In a 'behind the spotlight fanfic', the main characters could be anyone who is part of the world that exists out of the public eye in the original story. For instance, if it's a fanfic related to a theater production, it could be the understudies waiting for their chance to shine, the ushers who see all the drama both on and off stage, or the set designers who create the magical worlds for the actors. Their personalities, their hopes, and their challenges could be the central focus of the fanfic.
I don't know for sure as it depends on the specific fanfic. It could be the side characters who are usually in the background of the main story but are brought to the front in this fanfic. Maybe it's the managers, the makeup artists, or the stagehands who have their own stories to tell.
