Andrew - demon

You were an angel, a sweet, beautiful girl with white wings growing out of your back.Andrew is a demon, a tall guy with small black wings with sharp tips. Angels and demons don't get along very well, they're complete opposites, but most of them work together. That's what happened to you and Andrew. You had a common task, to keep an eye on one person on earth. But of course, when you go to the land where people live, no one will see you or feel your presence, even the person you will be looking after. You weren't very happy with your work partner, but you both had no choice.

So you met up with Andrew and went to earth...
