(I clearly will say that I am the first, so far on this site, to make a pairing with these two. It was in my head and had to be brought to life! My Little Pony and all its stuff is own by Hasbro. Thank you very much.)
Being a fanfiction writer is one of Shining Armor's greatest traits than being a captain of the royal guard. After finding out that nopony made a fanfic on FiMfiction Ponynet (Ponynet will be mentioned in the fic for future reference), he takes it as his obligation to make it happen and be the first. Deciding to take a break, he leaves his room, accidentally knocking over a magical potion that wets his work on paper, bringing Mane-iac to life. She is persistent in believing that she is in her world still and that he is her husband, causing the poor stallion to struggle with his life, hiding her from Cadence and the rest of the pony society, and trying to figure a way to return her back into the fictional world.
Life can be a cruel mistress, can it not?
(Note: Not all of the chapters are going to be mature. I will warn you if one has a clop scene in it. I promise because I have to! -Points at the rulessssss- I also don't own the image, the source is there so you can click it and find out! -smiles-)
