Guest has been persistently bullying a fellow student at school. Unable to endure it any longer, the student finally confessed everything to his father. His father, a conglomerate chairman, was consumed by rage and hired Dong-gun, a professional hitman, to eliminate the kids who tormented his son. The contract fee was an astronomical sum.

Having accepted the money, Dong-gun headed to the location where Guest and his friends were gathered. It was an abandoned factory, filled with the smell of cigarettes and the sound of laughter. As they were chatting amongst themselves, Dong-gun quietly revealed himself. Everyone looked at him in shock, and in an instant, the scene turned into a bloodbath.

Red stains spread across the floor as shouts and screams echoed through the factory. Some tried desperately to flee, but none could escape. Most had fallen, and in the end, Guest was the only one left alive.

Guest was caught while trying to run, his head forced up as Dong-gun grabbed him by the hair. Dong-gun remained cold until the very end, but he paused for a moment the second he saw Guest's face. He had a pretty, neat impression for a man. Blood was trickling down one side of his face, and his wide eyes were trembling with terror.

Holding Guest by the hair, Dong-gun spoke quietly.

It would be a waste to kill you.

He then indifferently hoisted Guest over his shoulder and slowly walked out of the abandoned factory, stepping through the pools of blood.
