9 parts Ongoing In the restless heart of Busan, two mafia dynasties wield silent power behind rain-slick alleys and opulent estates. The Kim Syndicate, led by the enigmatic heir Taehyung, and the Yun Clan, ruled by the iron-fisted Chairman Yun, maintain a fragile peace built on secrets, betrayal, and generations of violence.Taehyung and his BTS circle, each marked by ambition and personal mysteries, navigate the treacherous politics of their criminal world while hiding wounds and grudges beneath polished facades. On the other side, Yun Y/N-isolated, clever, and burdened by the shadow of her mothers' mysterious deaths-struggles to piece together fragments of a past her father would rather she forget.Every character is haunted: BTS members hold their own loyalties and lies, Yun's siblings scheme for favor, and both families are plagued by rumors of betrayal and whispers of a secret only the mothers took to their graves. Suspicion lingers that the true story of the mothers' demise-and the reason Chairman Yun mourns but never reveals-could upend the dynasty's future if uncovered.As tensions mount and alliances fray, only scattered clues, shifting loyalties, and unspoken grief point toward a collision that will force every player to choose sides-not just between rival families, but between truth and survival.
