Ok I have someone for this now. Thanks everyone.
Even Angels fall
A girl is found wounded by the road. your character finds her and brings her back to health. She doesn't seem to remember anything, and she acts as if everything around her is new and strange, as if she wasn't from earth. Is the girl crazy, or is it possible that she could be from somewhere else?
I don't have much of a plot beyond that, but we could work out more details. If anyone is intrested.
I could see this going very light, where the guy just wants to take care of her, and she sees him as her savior.
Or it could go the other way, and the person that saves her thinks that she belongs to him now. I could go either way.
eventually she would get some of her memories back as well.
