52 parts Complete MatureSeoul never sleeps, and neither do its crimes. A rookie cop walks into the Major Crimes Unit with nothing but a scarred past, a half-buttoned silk shirt, and three years of secrets buried under smoke and blood. Beside him, a senior detective... cold, relentless, carrying wounds that never healed... doesn't believe in charm, only discipline. Their collision is instant.
Cases burn fast: bodies in Itaewon clubs, whispers in back alleys, fires that hide more than they destroy. Each step forward uncovers another layer of corruption, another hidden bond, another betrayal buried where no badge can reach. The department isn't just chasing criminals; it's haunted by them.
Behind courtroom walls, arguments cut sharper than knives. At home, roommates become unlikely allies, informants turn into lifelines, and friendships bend dangerously close to breaking. Trust is tested in the smallest moments... in a glance across crime scene tape, in a smile that hides a weapon, in the silence between two men who both refuse to fall first.
And when the past finally resurfaces, it's not just the city on trial. It's them.
Because in Seoul... truth is never clean, loyalty is never free, and every badge comes with a cost.
