Oh Jung Se Plays a Director Haunted by His Own Success

Oh Jung Se is about to remind audiences why he is one of Korean drama's most compelling chameleons. JTBC's upcoming Saturday-Sunday drama We Are All Fighting Our Own Worthlessness — known by its Korean abbreviation 모자무싸 — has released the first character stills of Oh Jung Se as film director Park Kyung Se, a man whose outward success masks a devastating inner turmoil.

The newly revealed images show Park Kyung Se as a figure caught between confidence and collapse. He is a critically recognized filmmaker who should have every reason to feel accomplished, yet he cannot shake the gnawing sense that he does not truly deserve his achievements. Every word uttered by his friend Hwang Dong Man, played by Koo Kyo Hwan, cuts deeper than any public failure ever could.

A Masterclass Writer Returns

The drama is penned by Park Hae Young, the acclaimed screenwriter behind My Mister, one of the most emotionally resonant K-dramas ever produced. Her signature ability to explore ordinary people's quiet desperation with extraordinary depth makes her the ideal storyteller for a narrative about self-worth and the corrosive power of comparison.

Director Cha Young Hoon helms the project, which premieres on April 18, 2026 at 10:40 PM KST. The production has already generated significant buzz thanks to its powerhouse cast and Park Hae Young's involvement.

Koo Kyo Hwan's TV Drama Breakthrough

For Koo Kyo Hwan, this marks his first-ever lead role in a television drama. The actor, celebrated for his intense performances in films like Peninsula, D.P., and Escape, takes on the role of Hwang Dong Man — a man who has spent two decades chasing his dream of becoming a film director without ever getting his break. Surrounded by friends who seem to have figured life out, Dong Man is consumed by anguish and jealousy that threaten to destroy his closest relationships.

The casting of Koo Kyo Hwan alongside Oh Jung Se creates a fascinating dynamic. Both actors are known for their ability to inhabit psychologically complex characters, and the tension between Dong Man's sense of inadequacy and Kyung Se's hidden self-doubt promises to generate the kind of layered storytelling that Korean drama fans crave.

An All-Star Ensemble

The drama boasts a remarkable supporting cast that includes Go Yoon Jung, Kang Mal Geum, and Park Hae Jun. Each brings their own weight to a story that explores what happens when the people closest to us become mirrors reflecting our deepest insecurities. Production stills and teasers released so far have shown a drama committed to visual storytelling that matches its ambitious thematic scope.

Why This Drama Matters

In a K-drama landscape increasingly dominated by fantasy and romance, We Are All Fighting Our Own Worthlessness stands out for its unflinching look at a universal human experience. The question it poses — can you truly succeed if you never believe you deserve it? — resonates far beyond the screen. With Park Hae Young's writing, Koo Kyo Hwan's raw intensity, and Oh Jung Se's ability to convey volumes with a single expression, this may be one of the most anticipated dramas of spring 2026.

JTBC's track record of producing character-driven hits gives additional reason for optimism. As the April premiere approaches, all eyes will be on whether this creative team can deliver a drama that matches the weight of its premise.
