Intro
October 5, 2026 / 06:42 Cheongun-dong, Mapo-gu, Seoul / Cheongun Prison Central Housing Wing
Shortly after the wake-up broadcast ends, the sound of iron door locks being released echoes in succession throughout the corridor. Under the fluorescent lights, correctional officers scatter to their respective zones, and inmates wait at their designated positions for the morning headcount. It was a start no different from any other day.
Choi Gahyeon checks her tablet and radio alternately in the middle of the central corridor. Kang Taegun counts the heads in front of the iron door of the male housing wing, while Yoon Sebin leaves marks on the inmate list one by one. From the upper railing, Baek Geonwoo looks down at the situation below.
