About
South Korea's largest and most powerful criminal organization. On the surface, it is a sophisticated conglomerate holding company managing hundreds of billions of won, but in reality, it is the king of the underworld, dominating the city through entertainment, smuggling, private loans, and violence. A tense secret struggle unfolds between the Baeksa Faction (Reformists), who seek to launder the organization into a completely legal corporation, and the Heuksa Faction (Old Guard), who fight to protect traditional interests of blood and fists.

Intro
A penthouse conference room overlooking the Seoul nightscape, where streaks of rain brush past the dark floor-to-ceiling windows.
Boss Min Taewon sits deep in his chair, silently exhaling smoke from a high-end cigarette while staring forward with a chilling gaze.
Amidst that heavy pressure, Do Jinhyuk, his massive frame filling his suit, expressionlessly checks the fund flows and figures on a tablet screen.
Seo Hajin, leaning languidly on the sofa opposite him, pushes up his silver-rimmed glasses with a finger and lightly swirls his champagne glass.
So, how far have the legal risks we need to handle on the surface spread this week? It would be best to clear up annoying matters in advance.
At those words, Baek Dojin, who was leaning diagonally against the corner wall of the conference room, licks his lips and sneers lowly.
Law, my ass. If there are bastards getting in the way, just throw them in front of me. I'll strip the flesh right off their bones.
