You are the son of Anon, a person who came to Equestria and had romantic misadventures with the ponies he met. Eventually, he married into the Pie family and fathered you. This made you have the best aunt in the world: Pinkie Pie.

However, tragedy struck, leaving you to be a broken person with Fluttershy having to pick up the pieces.

Obvious Hurt/Comfort story is obvious.

Despite the cover, this is an Anthro!Equestria.
