Square Episode 4: So Ji-sub’s Relentless Revenge and the Dark Side of Seoul’s Underworld Captivate Viewers

A Brutal Return: Gi-jun’s Path of Vengeance Deepens

Episode 4 of 'Square' marks a pivotal moment as Gi-jun, portrayed by So Ji-sub, pushes further into the heart of Seoul’s criminal underworld. After the shocking events of the previous episodes, Gi-jun’s quest for revenge against the rival organization intensifies. The narrative reveals more about his complex relationship with his deceased brother Gi-seok and the power struggle between the two major gangs, Juun and Bongsan. The episode’s opening sequence, featuring a tense confrontation in a deserted warehouse, sets the tone for the relentless violence and moral ambiguity that define the series.
Viewers are drawn to Gi-jun’s internal conflict, as his sense of justice clashes with the brutal reality of the world he inhabits. So Ji-sub’s understated yet powerful performance, especially his expressive eyes and physical vulnerability, continues to receive widespread praise from critics and fans alike.

Action That Hurts: Raw, Gritty, and Realistic

One of the standout features of Episode 4 is its action choreography. Unlike the flashy, stylized fights common in many K-dramas, 'Square' opts for raw, almost painful realism. Gi-jun’s limp is not just a character detail; it shapes every fight, making each confrontation feel desperate and unpredictable. The baseball bat, now established as Gi-jun’s signature weapon, becomes a symbol of his determination and the violence that surrounds him.
Director Choi Sung-eun’s approach to action is deliberate and unpolished, emphasizing the physical toll that each battle takes on the characters. This authenticity resonates with viewers, many of whom have commented on social media about the “visceral impact” and “unfiltered brutality” of the show’s fight scenes.

Webtoon Roots: Faithful Adaptation and Fandom Expectations

‘Square’ is based on a popular webtoon known for its intense plot and striking visuals. Fans of the original have been closely watching how the series adapts key storylines and character arcs. Episode 4, in particular, stays true to the webtoon’s tone, maintaining the sense of unpredictability and emotional stakes.
Bloggers and critics have noted that the show’s success lies in its ability to balance loyalty to the source material with cinematic flair. The production team’s decision to preserve the webtoon’s gritty atmosphere and focus on Gi-jun’s relentless drive has been met with approval from longtime fans, who appreciate the respect shown to the original work.

Critical Acclaim: Reviews Highlight Performances and Direction

Recent articles from major outlets and drama blogs have highlighted So Ji-sub’s performance as a career-defining turn. Critics from MaxMovie and Queen praise his ability to convey deep emotion with minimal dialogue, relying instead on subtle gestures and intense stares.
Director Choi Sung-eun’s vision is also recognized for its cohesive storytelling and atmospheric world-building. The supporting cast, including Heo Joon-ho, Gong Myung, and special appearances by Cha Seung-won and Lee Jun-hyuk, add layers of intrigue and complexity to the narrative. The interplay between veteran actors and rising stars creates a dynamic energy that keeps viewers engaged.

Cultural Insight: Noir, Justice, and the Korean Urban Mythos

For international fans, understanding the cultural context of ‘Square’ adds depth to the viewing experience. The series draws on classic Korean noir traditions, blending themes of revenge, loyalty, and the blurred lines between good and evil. The setting—Seoul’s shadowy underbelly—serves as both a literal and metaphorical battleground for power and redemption.
