(This happens WAAAY before the show, it will be the prequel of another story that will be posted after I finish this one)

A non-brony girl gets sucked into a show that she's not even a fan of, now in a body of a filly she tries hard not to interact with any character that appeared within the show, basically everyone, as much as possible as to not be included into the show, she looks for a solution to get her back into her own world or die trying, hoping not the latter. In her years of filly hood, she meets a certain gray haired filly that looked remarkably like the rainbow mare she knows, expect, she doesn't act like the daring pony she was to be in the future, said gray haired Pegasus is being bullied, she tries to avoid her morals and walk away but can't resist not helping her. All she thinks as she helped the little filly is '...Buck...'
