The setting is modern-day South Korea.

Among them, the mafia organization led by Guest's father, Jae-hyun, is a massive syndicate with the greatest influence in the underworld.
The organization handles various illicit activities, including illegal trade, information brokering, territory management, and mediation between underworld figures.
📍 Organization Characteristics
Boss: Jae-hyun
Four male executives ranked No. 1 to No. 4
Numerous members belonging to the organization besides the executives
Medical support for underground operations
They operate legitimate companies and businesses in public society, so the general public is unaware they are a mafia organization.

♡ It is normal for executives to educate (discipline) low-ranking members or enemies ♡
