“The Defects” Director Oh Gi Hwan Shares Cast Highlights, Powerful Themes, and Must-Watch Moments Ahead of Premiere

The highly anticipated action thriller “The Defects” is gearing up for its premiere—and director Oh Gi Hwan is offering fans a deeper look into the drama’s intense storyline, complex characters, and powerful performances. Based on a popular webtoon, The Defects is shaping up to be one of the most emotionally charged and action-packed dramas of 2025.

With its premiere slated for July 21 at 10 p.m. KST, the series is already drawing attention for its gripping plot, stellar cast, and thought-provoking themes.

A Dark Yet Hopeful Storyline Rooted in Family and Survival

“The Defects” tells the haunting story of children who were abandoned by their adoptive parents and now fight for survival in a cruel, indifferent world. It’s a brutal narrative that doesn’t shy away from trauma and revenge, but director Oh Gi Hwan insists it also offers a glimmer of light through its exploration of family, resilience, and emotional connection.

“This is the work that asks the most fundamental questions out of everything I’ve directed so far,” said Oh. “Even as the director, I can’t wait to watch it myself.”

The production process was long and meticulous, with Oh emphasizing that the scriptwriting phase was particularly challenging—a testament to the care and complexity behind the story.

Spotlight on the Cast: Strength, Emotion, and Action

Oh Gi Hwan didn’t hold back in praising the drama’s main cast, each of whom brings something distinct and dynamic to the screen.

Yum Jung Ah: “The Commander”

“Yum Jung Ah was, in a word, a general—a true commander,” Oh remarked. “Her acting skills go without saying, but what stood out was her ability to grasp the overall situation of the drama. Whenever I wavered, she calmly helped steer the direction of the story.”

Known for her commanding screen presence, Yum Jung Ah is expected to deliver a performance that anchors the show both emotionally and thematically.

Won Jin Ah: The Action Ace

“She felt like a special agent on a mission,” Oh said. “Won Jin Ah took on most of her own action scenes and brought extraordinary emotional control to her performance.”

Her duality—balancing physical intensity with emotional vulnerability—will likely make her one of the drama’s breakout characters.

Choi Young Joon and Dex: Confident and Compelling

“Both Choi Young Joon and Dex embodied their characters with confidence and made a powerful impression,” he added. “All of the actors came together for a flawless ensemble.”

Whether seasoned or rising stars, the cast of The Defects is being positioned as one of the drama’s strongest assets.

Why “The Defects” Stands Out: Themes, Style, and Narrative

According to Oh Gi Hwan, The Defects sets itself apart through its:

Unique narrative direction
Tension-filled storytelling
Diverse and cinematic action sequences

The director emphasized that the series doesn't just rely on high-stakes thrills—it’s designed to blend darkness with light, and intensity with heart.

“Something too strong is not actually genuinely strong,” Oh reflected. “That’s why I made space for moments of comedy and emotion amid the chaos.”

This balanced approach is expected to create a more immersive and relatable experience for viewers.

Message to Viewers: Reflect, Relate, and Don’t Watch With Pressure

In a heartfelt conclusion, Oh Gi Hwan shared his hopes for the series:

“I hope this series encourages viewers to look again at the people beside them. That’s the goal and message I wanted to convey. Please enjoy The Defects without pressure and look forward to the premiere.”
