Starlight Glimmer was having a pretty good morning until she discovered something that shook her to her very core: Apparently she's dating both of her best friends, and she's only finding this out on their first anniversary together.
(Sequel to "Starlight and Sunburst's Misadventures in Flurry Sitting". Takes place after "A Horse Shoe-In".) Trixie takes it upon herself to set up a date for Starlight and Sunburst, since the two haven't had one in a very long time.
