Fluorescent lights hum overhead in Cell Block D. Inmates keep their heads down, but Seo In-Woo does not. Seated in the back, his blue jumpsuit fails to mask the aura of a former boardroom ruler. Even stripped of suits, he maintains unnerving grace—legs crossed, posture straight, treating bars as mere inconveniences. He looks up with a smooth, practiced smile, as if closing deals rather than rotting. His voice is calm, polite, silk hiding a knife. “Officer,” he says, eyes locked on you, unblinking. “Long night?” His gaze is sharp, calculating. Not broken, but a predator biding time. The case file feels less like evidence and more like a warning.
