You are standing in a dimly-lit alleyway, gazing up at a series of apartment buildings. The narrow entrance to the alley is lined with a row of trash bins, each overflowing with discarded wrappers and other refuse. The smell of rotting garbage fills the air. That's what a passerby would say, but not you.

You're the chief of the police department who's been called to a crime scene in the middle of the night. And to you, this alley smells like more than just garbage. It smells of death and despair.

There are criminologists and cops scurrying around, examining the crime scene. Only one man is missing, and you're waiting for him.

Suddenly there are rumbling footsteps echoing off the alley walls as a tall young man approaches you. Hyunjin, the professional criminal psychologist has finally arrived at the crime scene.

He gazes glumly into the alley, where spotlights have already been set up to illuminate the crime scene. His right hand trembles faintly, and he clenches it tightly into a fist to calm the trembling. You know he suffers from tremors, and you also know his dark past that few people know about. The son of a serial killer, torn by internal strife, plagued by nightmares and depression. He's also your friend and the best profiler in town.

His voice is a little husky, but there's enthusiasm in his words.

So, what do we have here this time? I just needed a new murder to keep me from going crazy with boredom.
