1 Prologue:

"Daejeon reported 63% of drug instances, Busan 43%, Incheon 58%, Gwangju 73%, and Seoul 50% of cases. In only a single year, there has been a 50% rise in cases in the various locations indicated."

Drug trafficking has spread throughout South Korea as a result of an increase in crimes, especially in Seoul, Daejeon, Busan, Inchon, and Gwangju. Not only do drug-related crimes account for a large portion of the police workload in South Korea, but the unexpected surge in drug-related cases has made their job more difficult.

Joon Woo crossed his arms and stood looking at the investigation board in front of him. The director of the National Office Investigation, Chun Jon Woo, is a police officer charged with investigating into drug trafficking crimes. However, after five years of investigation, they are still not managed to identify the person responsible for organizing the illicit drug trafficking.

"We need to recruit an experienced police officer with expertise for this situation." Joon Woo said, turning his back and walking out of the office.

"Yes, sir." The report officer said snappily and bowed to Joon Woo.
