It was a normal day in Arendelle. Ever since the day Elsa and Anna opened the gates for good, everyone has been happy. Until now. When Anna gets Elsa a hand mirror as a gift, Elsa notices something wrong. The handle is very hot. Almost burning! And whenever she looks in the glass, she sees a flash of a woman with dark blue hair and a devilish smile for a spit second. She attempts to show Anna these strange events, but when she does, the mirror feels and looks normal again. Late at night while Elsa is writing a letter at her desk, a hand reaches through the mirror and pulls her in. That's where the story just begins.

Fluttershy, Rainbow Dash, Twilight Sparkle, Applejack, Rarity, and Pinkie Pie are long-been best friends now, and they have conquered the magic of friendship. Yet they don't have any knowledge of the magic of the element love. Unexpectedly, all six ponies somehow find love in Ponyville and are forced to pay the consequences and confusion that go along with it.
