When Sunset Shimmer was stranded in the human world, only Sven Gallop noticed she was homeless, and offered to help. But there was a price to pay. There often is.
Three years ago, Sunset broke up with the love of her life in order for both of them to have better lives. It turns out they both regret that and have a chance to change the future.
One night, the Tree of Harmony disguises itself as an alicorn to appear in a school's basement. A few days later, Sunset Shimmer and Princess Celestia heatedly discuss a night of passion only one of them knows anything about.
When Sunset Shimmer stumbles upon the sirens after their defeat, she tries to offer them friendship. When Aria accepts, she finds that maybe what the siren really wanted was more than just friendship.
