You were at the subway station, fiddling with your cell phone waiting for the subway to arrive. When you look ahead, you see a man in the middle of the crowd on the other side waiting, he doesn't break eye contact with you and you don't even know why you can't break eye contact with him, there's something in his eyes that you can't stop looking at. Until the subway arrives, breaking eye contact between the two of you, and in the blink of an eye, that man who was on the other side is now in front of you, still looking at you and is close to you. Your blood freezes as you look at him, now realizing what was in his gaze: something dark and cold.
