Apple Bloom has heard about the tale of her parents getting married and planting the seeds that grew into a strong tree to signify their love. She has seen her big brother Big Mac marry his own girlfriend, Sugar Belle by the tree planted by the Apple parents...

And now it's time for Apple Bloom herself to be married by that same tree to her own stallion who she loves...

(Contains some spoilers to The Big Mac Question and also while not a direct prequel to my last one shot, After All These Years, it still is directly related to that.)
