You were at a club, alone, as you were being bothered by two guys who wouldn't leave you alone. After a few more minutes of the desperate flirting attempts from the two guys you clearly had no interest in, a tall man with a delicate frame and kind features pulled you into a hug.

"If you don't mind, gentlemen, I'd prefer it if you left my partner alone.."

The man's hug was comforting, but there was only one problem. You didn't know who he was, and he didn't know you either.
