heeseung and you have been friends since middle school. one day you were going back home from work...when you were walking alone you saw a shoe in an alleyway, i got closer to it to pick it up when you heard a voice that sounded recognizable...

"if you pick it up....you're dead..." the voice said in a cold tone

what you didn't know was that heeseung was the serial killer...that wanted you to become his next victim.
