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.
After making peace with the Dazzlings, Sunset decides to spend time with them individually. With Adagio and Sonata out of the way, she moves on to Aria, but what blooms from this is something neither of them ever expected.
