Sonata Dusk and her Sisters are back in Equestria, fixing their lives and making amends with those they left behind for their Desire.
Here she meets Pinkie Pie, a wonderful mare. They talk, they fall in love. This is a story about moments in their relationship, some small and some large. As long as their together, they're smiling.

Part of the Cornerverse-MLP Universe.
Edit-3/5/18: I went back and edited the first three chapters, adding more due to not only writing style changes, but also some developments from stories elsewhere in the continuity.
