Gangnam B-Side – A Dark and Stylish K-drama Crime Thriller

① Overall Impression

Gangnam B-Side is a gritty, gripping K-drama that dives deep into Seoul’s darkest corners. Released as a Disney+ original in late 2024, this 8-episode crime thriller brings together a detective, a prosecutor, and a gangster – all chasing a twisted trail of disappearances in the neon-lit streets of Gangnam.

What makes this K-drama stand out is its tone. It’s moody and cinematic, with a noir atmosphere that feels more like a movie than a TV series. Each character is morally gray, and the plot unfolds like a puzzle box – slow-burning, but worth every click.

The show doesn’t hold back. From brutal fight scenes to emotional twists, Gangnam B-Side offers a suspenseful ride that keeps you hooked while raising questions about power, loyalty, and survival.

② Rating (out of 10)

⭐⭐⭐⭐⭐⭐⭐⭐ 8.5/10
Gangnam B-Side earns high marks for its strong direction, compelling performances (especially by Jo Woo-jin and Ji Chang-wook), and fearless storytelling. The final act may be divisive, but the journey is dark, intense, and captivating.

③ Synopsis

When a series of young women mysteriously vanish in Gangnam, the city is thrown into panic. Among them is a popular club ace named Jae-hee.

To solve the case, detective Kang Dong-woo returns to his old beat. He’s joined by Min Seo-jin, a prosecutor using the case to climb the social ladder, and Yoon Gil-ho, a rogue operator from the Gangnam underworld.

Each has their own agenda. But as they peel back layers of corruption, secret connections, and personal betrayal, they find themselves up against a powerful black-market network far more dangerous than expected.

With brutal realism and stylish suspense, this K-drama delivers a dark twist on the classic detective genre.

④ Ending

The finale is intense, revealing the truth behind Jae-hee’s disappearance and the full scope of the criminal cartel. Each of the main characters makes a defining choice — some for justice, some for revenge, and some for redemption.

While not everyone gets a happy ending, the payoff is emotionally raw and satisfying. The final showdown is both tragic and cathartic, delivering a heavy punch and leaving no thread unresolved.
