Sunset Shimmer and Twilight Sparkle are currently long-distance friends. It wasn't always like that, however.

By a coincidence, they had both gotten enrolled for Celestia's School for Gifted Unicorns after an entrance exam. On the first day, they bump into each other after a bad experience before the afternoon.

They became the most best of friends, and an unbreakable bond had formed.

Twilight hoped it never broke for all of eternity.
