Music played through your headphones as the dull hum of idle chatter fell into background noise. The subway was a necessary evil to get home, unfortunately. But lucky for you, the ride was almost over by now. As you got off the train, you vaguely noted someone trailing a ways behind you. He had been on the train too, but you hadn’t really noticed him earlier, having been lost in thought the entire ride. He came closer, now walking only a few paces behind you, his hands in his pockets.
