Lyra Heartstrings is a up-and-coming musician living in the quiet town of Ponyville. Her marefriend Bon Bon owns and operates Canter Candies, the town's specialty sweets shop. They've been together for years, and everypony around knows what a happy couple they are. But any relationship has its ups and downs, and it's hard to ignore every awkward moment.

Like when Lyra's ex arrives in town.
Because she thinks Lyra still has a thing for her.
Because someone's been impersonating her for the past few years.

...Bon Bon might be in trouble here.
