In the third episode of Gangnam B-Side, the narrative unfolds with a somber discovery and a heated confrontation. The police find Lee Gang-su's lifeless body, setting the stage for a tense standoff between Dong-woo and Seo-jin on the bridge. Dong-woo's fervent belief that Yun was orchestrating Gil-ho's murder and framing him clashes with Seo-jin's skepticism, planting seeds of doubt in her mind about the truth she once held dear.
The episode delves deeper into the murky waters ofGangnamB-Side's criminal underbelly as Seo-jin meets with Joon-seo, who introduces her to a clandestine chat application used by everyone in their illicit trade. Joon-seo's nonchalant revelation that Gil-ho is alive and his eagerness to celebrate with Seo-jin once their business is concluded only serve to deepen her suspicions. As she begins to probe further into Joon-seo's true intentions, she is blindsided by the news that the weapon used to murder Gang-su belonged to Gil-ho, a twist that leaves her reeling.
Meanwhile, Dong-woo's investigation leads him to an arcade, where he uncovers subtle clues that link the place to Gangnam Trading. His colleague's discovery of Jae-hee, Jung-hwa, and Lemon's social media profiles reveals their prominence in the Gangnam club scene. Dong-woo sets out to locate Lemon, who is not only alive but still in Korea, while Gil-ho is left to ponder his past with Madam Baek and Jae-hee.
As Dong-woo and Kim Jang-ho follow Lemon, they stumble upon a building that holds a dark history for them. Inside, they uncover a discreet hostess bar, with rooms littered with drug bags. Dong-woo encounters Ju Yun engaged in illicit activities with two young girls and promptly arrests him and Lemon. Tak Joo-il instructs Seo-jin to dismiss Yun, who in turn tells her to contact Joon-seo, assuring her that he will keep all secrets buried for the time being.
In a desperate bid to settle scores with Yoon-seo, Gil-ho finds himself at a crossroads. Yun, on the other hand, decides to confide in Seo-jin, who enlists Dong-woo's help. Initially reluctant to trust her, Dong-woo eventually cooperates, sharing everything he knows. However, Joon-seo's call to Seo-jin cancels her meeting with Yun, revealing that he is aware of Jae-hee and Gil-ho's whereabouts. As the characters prepare to confront Joon-seo, he invites the men responsible for Jung-hwa's murder to spend one last "enjoyable" night with Jae-hee, setting the stage for a potentially explosive encounter.
The pacing of Gangnam B-Side has been a point of contention, with the series often criticized for its slow progression. Each episode raises expectations for increased complexity and tighter runtime, only to disappoint by focusing on mundane details and sparse information. This third installment offers a glimpse into the characters' backstories, but it lacks the shock value that could have elevated the narrative. The series seems to be stretching what could have been condensed into a single episode, leading to a sense of frustration among viewers.
Despite boasting a talented cast, Gangnam B-Side fails to generate the thrill and anticipation that one would expect from a crime drama of this caliber. The slow-burning plot and lack of significant revelations leave the audience wanting more, as the series struggles to find its footing in a crowded genre. With high expectations comes great responsibility, and Gangnam B-Side's third episode, while offering a deeper dive into the characters' lives, ultimately falls short of delivering the gripping, edge-of-your-seat experience that fans have been hoping for.
