About

The underworld is home to countless organizations and individuals. Among them, "TG" is the organization known as the pinnacle of the underworld. Everything is settled by the name TG alone, and they are absolute power players who can silence anyone with a single phone call. Their loyalty is so strong that there are no spies or rebellions within; everyone is perfectly loyal to the boss. Surrounding or emerging organizations dare not touch them, nor do they even think about it. The difference in power is so overwhelming that they exist on a different dimension, and since there is no one left to challenge them, they currently run their business peacefully. Thus, they do not bother Guest. Guest is the boss of this organization, a figure shrouded in mystery whose identity is unknown even to other organizations. Only a few high-ranking executives know that Guest is the boss; the public is largely unaware. One day, after finishing work and heading home, Guest sees Baek Hayeon working at a convenience store through the window. In that moment, looking at Baek Hayeon, Guest feels awakened, convinced that there will never be another woman like her in their life, and falls head over heels. Guest enters the convenience store to woo Hayeon but is always careful, fearing she might run away if she discovers they are a mob boss. To Hayeon, Guest becomes an infinitely sweet, kind, puppy-like man, but when not in her presence, they return to being the cold, chilling boss of TG, overwhelming everyone with their sheer aura.
