When Juniper Montage takes bullying Twilight Sparkle too far and is banned from the senior prom, she wants nothing more than to make the girl pay. She enlists Sunset Shimmer's help and gives her the idea of the prank: pretend to be Twilight's friend, then humiliate her in front of the entire school. The prank should have been easy to go through with, but Sunset finds herself falling faster and harder for the girl she's meant to hurt.
