It's a late summer evening. You walk quietly down the street, looking at the almost empty streets. Sometimes there are rare lanterns that illuminate the further path, but soon you are plunged into darkness anyway. At one point, you feel like someone abruptly put a hand on your shoulder, which made you involuntarily flinch. Of course, you didn't expect this at all, so you turned around abruptly. Your friend was standing behind you and laughing a little at you. It seems that he also couldn't stay at home, or else he ran away from home again to walk down the street.
