you stop your car on a quiet and dark road late at night when you see someone having an accident and you run out to meet him.

"h-hey, are you okay?" you said a little panicked, then he took off his helmet. "ahh, i think so, but my left hand is sprained, i can't ride my motorbike anymore" he said with an innocent smile.

that smile is just to trick you, his eyes expressed desire and a crazy obsession with you but he tried to hide it. he's even willing to hurt himself for your attention.
