Climax (클라이맥스) is a 2026 Korean noir drama that aired on ENA every Monday and Tuesday at 10:00 PM KST, from March 16 to April 14, 2026 (10 episodes). Also streaming on Disney+, Genie TV, and Viu. Directed by Lee Ji‑won and co‑written with Shin Ye‑seul, the series asks one brutal question: How far will ambition push you — and what’s left when it’s done?
Set at the intersection of politics, big business, and the entertainment industry, Climax assembles an all‑star cast led by Ju Ji‑hoon, Ha Ji‑won, Nana, Cha Joo‑young, and Oh Jung‑se. For five weeks it dominated conversations — topping Disney+’s Korean Series chart for three consecutive weeks, ranking #1 on Viu in Indonesia and Thailand, and holding the #1 spot on Naver OpenTalk, Kinolights, and WatchaPedia simultaneously.
But did it stick the landing? In this full series review, we break down everything — the cast, the episode‑by‑episode ratings rollercoaster, the plot’s highs and lows, the controversial open ending, and whether Season 2 is actually happening.
Cast and Characters

| Ju Ji‑hoon (주지훈) | Bang Tae‑seop (방태섭) | Prosecutor‑turned‑politician consumed by ambition; the show’s moral void |
| Ha Ji‑won (하지원) | Chu Sang‑a (추상아) | Former actress and Tae‑seop’s wife; survival instinct personified |

Episode‑by‑Episode Ratings (Nielsen Korea, Paid‑Platform Households, Nationwide)
| Episode | Air Date | Rating (%) | Note |
|---|---|---|---|
| 1 | Mar 16 | 2.9 | Premiere |
| 2 | Mar 17 | 3.8 | |
| 3 | Mar 23 | 3.9 | Early high |
| 4 | Mar 24 | 3.5 | |
| 5 | Mar 30 | 3.1 | |
| 6 | Mar 31 | 2.6 | |
| 7 | Apr 6 | 2.7 | |
| 8 | Apr 7 | 2.9 | Upward trend begins |
| 9 | Apr 13 | 3.3 | Mon‑Tue #1 (IZE) |
| 10 | Apr 14 | 3.9 | Series high; peak 4.6% Bundang, 4.8% Seoul metro (Nate · Chosun Biz · Financial News) |
The ratings tell a clear U‑shaped story. After a solid premiere week (2.9% → 3.8%), mid‑series fatigue dragged numbers down to 2.6% by Episode 6. The recovery only began in Episode 8, accelerating through the finale’s 3.9% — tying the Episode 3 early peak and setting the series record. The minute‑peak of 4.8% in the Seoul metropolitan area during the final act shows that those who stayed were completely locked in.
By comparison, Climax never matched the heights of ENA’s flagship Extraordinary Attorney Woo (which peaked above 17%), but it comfortably secured the #2 weekday drama slot on ENA and ranked #8 in the network’s all‑time ratings. More importantly, its Disney+ performance was dominant: #1 in Korean Series for three straight weeks (March 18 – April 11), and #1 on Viu in Indonesia and Thailand with top‑5 finishes in six Asian markets.
Plot Overview — From Ambition to Ashes
Act 1 (Episodes 1–3): We meet Bang Tae‑seop, a prosecutor with political ambitions, and his wife Chu Sang‑a, a former actress hiding a complicated past. Their marriage is strategic, not romantic. When WR Group chairwoman Lee Yang‑mi extends an invitation into her power circle, Tae‑seop jumps in — unaware that Yang‑mi’s game has no winners except herself. Meanwhile, Sang‑a’s former lover Hwang Jeong‑won resurfaces, threatening the carefully constructed facade.
Act 2 (Episodes 4–7): The middle stretch is where Climax loses momentum. Tae‑seop’s political maneuvering becomes repetitive — alliances shift, betrayals multiply, but the stakes feel abstract. The saving grace is the Yang‑mi character: Cha Joo‑young turns every scene into a masterclass of controlled menace. The relationship between Sang‑a and Jeong‑won deepens, adding emotional weight that the political thriller side lacks.
Act 3 (Episodes 8–10): Everything ignites. Yang‑mi leaks a manipulated video of Sang‑a and Jeong‑won, destroying Tae‑seop’s campaign overnight. Jeong‑won is stabbed while protecting Sang‑a and dies in her arms — the series’ most devastating scene. A one‑year time‑skip follows: Tae‑seop infiltrates Yang‑mi’s faction as an advisor to presidential candidate Son Guk‑won, while Sang‑a rebuilds her career and secretly amasses leverage using a diary of political corruption. Together, they expose Yang‑mi’s crimes on the 9 o’clock news, leading to her arrest. But two years later, Yang‑mi receives a presidential pardon, calls Sang‑a from outside prison, and the cycle of fear begins again.
What Worked
Ju Ji‑hoon’s ice‑cold precision. As Bang Tae‑seop, Ju Ji‑hoon barely raises his voice — and that’s exactly what makes him terrifying. His performance lives in micro‑expressions: a jaw clench when cornered, a half‑smile when he knows he’s already won. It’s the kind of restrained acting that rewards close attention, and it anchors a show that could easily have tipped into melodrama.
Cha Joo‑young’s villain for the ages. Lee Yang‑mi is the character you cannot look away from. Cha Joo‑young plays her with a warmth that makes the cruelty hit harder — she smiles at you right before she destroys you. The boardroom confrontations, the phone calls dripping with coded threats, the final prison‑release scene — Yang‑mi owns the best moments of this series.
Nana’s tragic gravity. Hwang Jeong‑won has limited screen time compared to the leads, but Nana makes every second count. Her death scene in Episode 9 is the emotional turning point of the entire show. The way she transitions from resigned acceptance to desperate action in her final moments is the kind of performance that lingers long after the credits roll.
Busan locations and cinematography. Shot extensively at the Busan Film Studio and various locations across the city (including the repurposed mayoral residence), Climax uses its settings as a character. The rain‑soaked streets, the cold glass towers, the cramped back‑alley offices — every frame reinforces the noir atmosphere.
The OST. Elaine Kim’s “Summit Game” became the unofficial anthem of the series, its pulsing rhythm perfectly matching Tae‑seop’s calculated moves. The full soundtrack — available on Spotify and YouTube — leans heavily into electronic noir, and it works.
What Didn’t Work
The mid‑series sag (Episodes 4–7). This is where Climax lost a significant portion of its audience — ratings dropped from 3.5% to 2.6%. The political scheming becomes circular: alliances form, break, and reform without meaningful consequences. Characters like Kwon Jong‑uk and Son Guk‑won remain underwritten, serving as plot devices rather than fully realized people.
Ten episodes weren’t enough — or were too many. The series sits in an awkward middle ground. Some subplots (the Daeyang Fund, the aspirin scandal) feel rushed, while others (Tae‑seop’s repeated strategic pivots) feel stretched. A tighter 8‑episode run or a more expansive 16‑episode structure might have served the story better.
The finale’s second half. The final 20 minutes compress a two‑year time‑skip, a presidential pardon, an international film award, a drug relapse, and a teaser for Season 2 into a breathless montage. Each of these beats deserved room to breathe. Instead, they feel like a checklist — especially Yang‑mi’s pardon, which arrives without narrative setup and undermines the catharsis of her arrest.
The open ending cuts both ways. If Season 2 happens, the finale is a brilliant setup. If it doesn’t, Climax ends as an incomplete story — a thriller that builds to a climax it never fully delivers.
The Ending Explained and Season 2 Prospects
The final scene is deliberately unresolved. Lee Yang‑mi, released on a special presidential pardon after serving less than two years of a 20‑year sentence, calls Sang‑a directly. Sang‑a — who has been struggling with fear and substance use since the scandal — collapses after taking pills. Tae‑seop finds her and carries her out. They face the press together, hand in hand, projecting unity even as everything crumbles underneath.
The unresolved threads are numerous: Chairman Kwon Se‑myung regains consciousness after years in a coma, potentially reshuffling the entire WR Group power structure. Yang‑mi is free and clearly not done. Sang‑a’s mental health is deteriorating. Tae‑seop’s political ascent — now as a serious presidential contender — puts him directly in Yang‑mi’s crosshairs again.
As of April 15, 2026, no official Season 2 announcement has been made. However, the combination of strong streaming performance (Disney+ #1 for three weeks, Viu dominance across Southeast Asia), the deliberately open narrative, and social media demand makes a continuation plausible. ENA and the production team have been carefully non‑committal in post‑finale interviews, which in K‑drama industry language usually means “we’re waiting for the numbers to justify it.”
Final Verdict — 7.8 / 10
Climax is a bold, ambitious noir that dares to say the quiet part loud: power doesn’t corrupt — it reveals. When the series is firing on all cylinders — Ju Ji‑hoon’s glacial calculation, Cha Joo‑young’s smiling cruelty, Nana’s heartbreaking sacrifice — it stands among the best K‑dramas of 2026. But the soft middle, the undercooked supporting characters, and a finale that tries to do too much in too little time keep it from greatness.
If you stayed through the mid‑series dip, the final three episodes reward your patience. If Season 2 arrives, the open ending transforms from a flaw into a masterstroke. For now, Climax is a flawed gem — brilliant in pieces, unfinished as a whole.
Rating: 7.8 / 10
One‑line verdict: “A daring noir that burns bright but ends in smoke — stunning performances and bold storytelling just barely outweigh a saggy middle and a rushed finale.”
