Trivia, insights & behind the scenes
The show weaponizes mundane infrastructure — traffic lights, road markings — as storytelling devices, making the invisible violence of urban planning viscerally personal.
Heo Sung-tae (Jeong Chae-man) was cast 48 hours before filming after the original actor withdrew; his improvisational gruffness became the team's accidental anchor.
