ENA’s upcoming 2026 drama, “Climax,” has officially locked in an impressive lineup of top-tier actors, including Ju Ji Hoon, Ha Ji Won, Nana, Oh Jung Se, and Cha Joo Young.
Announced on November 24, 2025, this powerful casting combination is generating significant buzz, promising a compelling and intense narrative centered on the brutal pursuit of power within South Korea’s elite circles.
Touted as a fierce survival drama, “Climax” will delve into the intertwined fates of individuals willing to sacrifice everything to reach the top.
The Intense Plot and Visionary Director
The drama is set to explore the darkest corners of ambition, focusing on prosecutor Bang Tae Seob’s journey as he immerses himself in a highly influential cartel.
His goal is singular and ruthless: to ascend to the highest position of power in the nation.
The narrative structure is built around exposing the grim reality and ugly side of this cartel, where desires clash and catastrophic decisions are made, ultimately promising a powerful and suspenseful viewing experience.
Guiding this intricate story is director Lee Ji Won, a highly respected filmmaker who previously earned the prestigious New Director Award at the Baeksang Arts Awards for her acclaimed film “Miss Baek.”
Her ability to craft delicate mise-en-scène (visual staging) and demonstrate outstanding, sensitive direction has been lauded by critics.
The production team for “Climax” emphasized the director’s partnership with a trusted cast, noting that the resulting synergy will create a strong and powerful project.
They specifically highlighted the amazing charm of the drama’s narrative, which revolves around the complex, intertwined desires and high-stakes decisions of its main characters.
Unpacking the Complex Leading Roles
The main cast members have been assigned roles that are key players in the drama’s high-stakes game of political and financial maneuvering:
- Ju Ji Hoon as Bang Tae Seob: The versatile actor, known for his roles in Kingdom and Hyena, takes on the leading role of Bang Tae Seob, a star prosecutor consumed by ambition. His professional life is intertwined with his personal life, as he is married to South Korea’s former top actress, Chu Sang Ah. His relentless drive to climb the societal ladder forms the core conflict of the series.
- Ha Ji Won as Chu Sang Ah: Known for her powerful performances in dramas like Secret Garden and Empress Ki, Ha Ji Won will portray Chu Sang Ah. Once the greatest actress in South Korea, her status has diminished since marrying Tae Seob, and she is now often treated as a “washed-up actress.” Her role suggests a woman navigating the treacherous social waters surrounding her husband’s ambitions and her own lost identity.
- Nana as Hwang Jung Won: The former After School member turned critically acclaimed actress (The Good Wife, Mask Girl) is cast as Hwang Jung Won. Her character is highly significant, as she operates secretly as an informant for Bang Tae Seob. More importantly, she holds the vital key—the “Pandora’s Box”—to exposing the deepest secrets and most corrupt dealings of the powerful cartel, making her a target and a threat to everyone involved.

His character is positioned in a fierce battle for the successor position of the massive corporation, indicating a powerful internal struggle for control of one of the nation’s economic pillars.
- Cha Joo Young as Lee Yang Mi: Rounding out the primary cast is Cha Joo Young, who gained immense popularity for her roles in hits like The Glory.
