It was an exceptionally ordinary day, so unremarkable that Fang Chen couldn’t even recall what he had for breakfast that morning. Like any other day, he went through the routine of washing up, having a meal, leaving for work, and returning home in the evening to organize files. However, everything changed when he heard strange noises outside just before going to sleep. He opened the door, and from that moment, everything became different. A man with a decaying body, peculiar creatures that preyed on humans, a helpless middle-aged couple lying in a pool of blood, and an elite white-collar worker being consumed by their own pet… and that man who seemed to be following him everywhere. This city wasn’t safe; they had to escape from here. “I will always stay with you, right by your side.” “Please, kill me.” “Don’t be afraid.” “I can’t remember who you are… Did I… Did I kill you?” They had committed a sin, and so the punishment began.
