In a universe where an ancient tragedy was averted, Pearl Rose goes to her teacher, Twilight Sparkle, when she and her longtime girlfriend break up. But then gets a shock.

The real rulers of Equestria wish to meet both of them. But there is more to it than just a friendly visit. Now not only will a secret be revealed at last.

But two hearts will find the love they have always longed for.

Just to be clear on the cover image. That is just the size difference between Twilight and Pearl in this universe. Pearl is very much over 18 in the story.
