Cold Hearted {Durarara x Reader}

EDIT: This will never be finished. I apologize, but this story is the bane of my existence. Y/N is a cold hearted girl. She didn't care for humans, but she loved to toy with them. Some might say she's insane. Some might say she's just misunderstood. She doesn't care what they say. She just likes what she does. Durara...
