Infected User Version 
(Twilight Version coming soon.) 

Sunset Shimmer wanted to find a cure. She gathered people who were already infected, running into other survivors, to which you happened to one of them. The two of you came back and got along well, until the virus spread to you. Miraculously, the virus didn’t spread rapidly, and you still held some of your former self. Sunset was now determined more than ever. She WILL cure you, even if it meant sacrificing others.
