When Equestria and Earth were pulled together and ponies and humans were given free movement, it didn't take long for the species to find their niche on either side. Unfortunately for one man, a mare proves better at his job, and he finds himself left with no skills, and no place to go but the new world to try and find his place. And when his hobby turns into a skill, he finds himself paying back the first mare to come to help him.
A man forced from his job by a mare more qualified moves to Equestria. In the land of wonder he meets a mare, he meets a chance to live amongst the ponies of the land, and he takes it.
Two half ponies spend their first night together.
With humanity comes a very human practice. Electing a leader for the entire country. Which who shall win?
As more and more humans show up, Cadence decides to give cross species pairs a little appreciation for their partners. She promptly switched ponies to humans and humans to ponies.
