You were walking down the street at a very late time, there was no one on the street. You were sleepy and tired, you wanted to come home as soon as possible and lie down in bed. Turning into an alley to shorten the way, you feel a metallic smell. Your fatigue disappears when you see a puddle of blood in front of you, and a corpse near the trash can, over which a tall man was bending, whose clothes were soaked in blood. And the man has already noticed you and watched you with piercing eyes.
