You often noticed the looks of a strange, tall guy at the university. Maybe it would be something normal if you did not meet him literally always..

At night, you sat on the windowsill in your room, looking out the window. Your eyes caught a familiar figure standing in the rain, the figure was clearly looking out your window, and perhaps knew you were looking too. It was a tall guy in black clothes. His face was covered with a cap, and his hands were shaking nervously in the rain.
