It was midnight and all that was heard was the minor flickering of street lights and chains. These chains were the emblem of threat, making every single person run for their lives; and these chains belonged to a dangerous serial killer, Woojin. Woojin was known for his ruthlessness and impulsive actions, murdering anyone in his sight.

He trudged beside the closed shops, his breath heavy and deadly, with his men following behind, joking and laughing. Woojin froze when he sensed a familiar presence, and turned to a alleyway to find his high school ex, Soohan, unconscious in the cold.
