Angel of Mercy

I don't know why I got stabbed. I don't know why I healed overnight. 

I don't know why I keep seeing the same guy in my dreams, on the sidewalk, at the minimart near my apartment - the insanely hot guy with the piercing blue eyes that nobody can see but me. 

I have to follow him. I have to talk to him. 

And he's not the only one stalking me. That guy with the knife? He's still out there, and he knows where I live.

I have to know. What am I now? Am I still human? Am I part angel? Or am I something new?
