Webtoon to Screen: A Revenge Tale Begins
“Mercy for None” started as the webcomic Plaza Wars: Mercy for None. Creator Oh Se Hyung drew readers into a world of gang feuds and heartbreak. Netflix chose the story for its raw emotion and dark style.
Producers signed on in mid-2023 and tapped screenwriter Kyun Tae Kim to adapt the plot. They aimed to keep the comic’s grit while adding cinematic flair. Fans watched as news of the project spread online. Planning took months before cameras rolled. In the end, the move from webtoon to TV set the stage for a revenge drama unlike any other.
Assembling the Cast: Faces Behind the Fury
Producers gathered a strong lead in So Ji-sub. He plays Nam Gi-jun, a retired gangster drawn back by his brother’s death. Heo Jun-ho stars as Lee Joo-woon, the old boss with fresh ambition. Ahn Gil-kang joins as rival leader Gu Bong-san. Lee Beom-soo steps in as the crime-scene cleaner with hidden motives.
Add Gong Myung and Choo Young-woo, and the ensemble brings depth to each fight and betrayal. Director Choi Sung-eun praised the cast’s “talented ingredients” for giving him creative freedom. Together, they turn words on a page into living, breathing danger.

Pre-Production and Scouting: From Seoul Studios to Streets
Before filming began, the team toured key sites around Seoul and Busan. They scouted gritty alleys and sleek office blocks. They tested lighting in parking lots for tight-space fights. They met with local officials to secure the necessary permits. In October 2023, they broke ground on both indoor stages and outdoor blocks.
Art directors dressed sets with neon signs and steel barrels. Stunt coordinators mapped out chase routes through crowded markets. Every choice aimed to highlight tension and mood. This groundwork proved vital when the shoot kicked off later that fall.
Filming in Seoul: Urban Noir Unveiled
Production took place entirely in Seoul from October 2023 to March 2024. The team turned Gangnam’s polished towers into crime-boss lairs. They filmed night scenes in Itaewon’s neon-lit streets to capture the danger that lurks after dark. They used the Incheon docks for tense standoffs by the water.
Inside the Pullman Ambassador Hotel’s ballroom, they staged a key press scene with the whole cast. Everywhere they shot, Seoul’s mix of old brick and modern glass added dramatic grit. The city itself became a character in this revenge thriller.

Scenery Shift: Busan’s Colorful Backdrop
In Busan, production moved to Gamcheon Culture Village and Jagalchi Fish Market. Gamcheon’s bright murals and steep lanes gave a quiet contrast to Seoul’s steel canyons. The crew shot reflection scenes where characters pause before their next move.
At Jagalchi, narrow alleys and crowded stalls became the setting for a high-speed chase. The noisy market added real tension and danger. Local vendors cheered the cast on while filming. This shift in scenery broadened the show’s visual appeal and deepened its emotional resonance.
Directorial Vision: Crafting a Dark Atmosphere
Director Choi Sung-eun steered the project with a clear vision. He wanted each frame to feel charged and raw. He worked closely with the cinematographer to use shadows and neon lights. Choi said the cast’s skill gave him “creative freedom” to push scenes harder.
He aimed for natural performances in strict settings. He chose fundamental city blocks over studio builds whenever possible. His goal was simple: let the locations speak for themselves. When an actor battles under a flickering streetlamp or searches a quiet village lane, you feel every heartbeat and thunder of boots.
Post-Production and Release: The Road Ahead
After wrapping in March 2024, editors dove into a months-long cut. They matched Seoul’s fast pace with quick edits and Busan’s calm with longer shots. Sound designers added engine roars and echoing footfalls. Netflix is scheduled to launch in mid-2025 to tap into the global K-drama buzz.
Early teasers focused on the stark cityscapes and Nam Gi-jun’s haunted gaze. Critics already praise the series for its visual style and strong performances. Fans eagerly await the launch day on Netflix to see if the series lives up to its promise of grit, heart, and non-stop action.
Final Words
“Mercy for None” stands out as more than a revenge story. It shows how setting, cast, and direction weave together to build tension. From its webtoon origin to the bright alleys of Gamcheon, each element adds depth.
The series reminds us that where a story unfolds is as vital as what unfolds. It also proves that a talented cast and a bold director can turn city streets into a living painting of noir drama. As the series streams, viewers will carry its dark beauty long after the credits roll.
