Where to Watch Gangnam B-Side: Korean Crime Thriller Streaming Now

Gangnam B-Side (Korean: 강남 비-사이드) is a South Korean crime thriller that masterfully intertwines suspense with social realism, making it one of Disney+’s most gripping Korean originals to date. Written and directed by Park Noo-ri, the series brings to life the glitzy yet shadowy Gangnam district of Seoul, a neighborhood famous for its luxurious lifestyle but tainted by its hidden underworld.

The story revolves around Detective Kang Dong-woo, played by Jo Woo-jin, who, after uncovering corruption in his own police force, is ostracized by peers and family. Drawn back to Gangnam after the mysterious disappearance of his daughter’s friend Kim Jae-hee (Kim Hyeong-seo), Kang teams up with a morally ambiguous broker, Yoon Gil-ho (Ji Chang-wook), and the determined prosecutor Min Seo-jin (Ha Yoon-kyung). Together, they navigate the dangerous corridors of Gangnam's elite clubs, delving into a web of narcotics, vice, and corruption that implicates the city’s wealthiest elites.

A Stellar Cast and Riveting Performances

The show’s strength lies in its richly developed characters. Jo Woo-jin shines as the flawed yet relentless detective, and Ji Chang-wook’s portrayal of Yoon Gil-ho, a broker torn between survival and loyalty, adds depth to the narrative. Kim Hyeong-seo (better known as the singer BIBI) delivers a standout performance as Kim Jae-hee, a runaway turned club ace whose tragic yet hopeful journey becomes a central thread in the story. Ha Yoon-kyung’s Min Seo-jin adds a touch of determination and humanity to the trio, making this ensemble cast one of the series’ highlights.

Themes of Glamour and Grit

Set against the neon-lit backdrop of Gangnam, the series offers a vivid exploration of duality—the dazzling surface of wealth and the lurking shadows of crime. Drawing from writer Joo Won-kyu’s real-life experiences as a driver for call girls, the narrative feels both grounded and intensely dramatic. Director Park Noo-ri amplifies this realism by incorporating insights from club promoters, prosecutors, and police officers, resulting in a gripping tale that immerses viewers in the stark realities of Gangnam’s underground scene.
