Levi's Little Titan with a Tail(boyxboy)

Okay, so I decided to make a series of fairy tale au stories of my OTPs. Feel free to leave requests, and don't forget to read my Otaku lovelies!!!!!!!!

All Eren wanted was to visit the surface and know more about the human. His biggest dream was to live among them and do what they do.
But when he goes up to the surface, drawn by colors bursting in the sky, he finds a new reason why he wants to be human.
