The Price of Confession: Murder Mystery with Powerhouse Cast
Premiere: December 5, 2025
Kicking off the month is this psychological thriller featuring three of Korea’s most acclaimed actors. Jeon Do Yeon, Kim Go Eun, and Park Hae Soo headline a twisted tale where a woman suspected of murdering her husband encounters a mysterious figure known as “the witch.”
An Yun Su’s simple dream of family happiness shatters when her husband dies under suspicious circumstances. As she fights to prove her innocence, dark secrets emerge that challenge everything she believed about her life. The 12-episode series promises weekly revelations that’ll keep audiences theorizing until the final episode.
With director Lee Jung-hyo at the helm and this star-studded ensemble, The Price of Confession positions itself as December’s prestige drama. For fans of complex female leads and psychological narratives, this series delivers the sophisticated storytelling K-dramas are renowned for.
The Great Flood: Disaster Spectacle Meets Human Survival
Premiere: December 19, 2025
Just in time for holiday viewing, this disaster film plunges Earth into catastrophic flooding. Kim Da Mi and Park Hae Soo (yes, he’s everywhere this month!) star in director Kim Byung Woo’s vision of humanity’s struggle against nature’s fury.
The 106-minute film centers on An Na, an AI researcher, and Hee Jo, a security specialist, trapped in a sinking apartment building. As water levels rise, the film explores not just survival but deeper questions: Why is Hee Jo so determined to save An Na specifically? Who orchestrated this disaster?
Disaster movies consistently perform well on Netflix, and with Korea’s reputation for spectacular action sequences and emotional storytelling, The Great Flood could become the streaming platform’s next viral hit. Expect stunning visual effects, heart-pounding tension, and the human drama that makes Korean disaster content resonate globally.
Cashero: The Superhero Series Worth Its Weight in Cash
Release: December TBA (possibly delayed to January 2026)
The most anticipated title remains maddeningly undated. Cashero follows Kang Sang Ung, a public servant with a unique superpower—his strength increases based on how much cash he carries. Yes, you read that correctly. His abilities literally depend on his bank account.
This deliciously absurd premise tackles real-world anxieties about money while delivering superhero action. Lee Jun Ho leads an ensemble cast including Kim Hye Joon and Kim Byung Chul in this 8-episode fantasy that’s been delayed multiple times.
Speculation suggests either a pre-Christmas drop or January 2026 delay due to scheduling conflicts with Stranger Things. Regardless, when Cashero finally arrives, it promises fresh perspective on the superhero genre through Korea’s satirical lens.
For enthusiasts of genre-bending content and superhero narratives, Cashero represents the experimental storytelling that makes K-content so compelling internationally.
Dynamite Kiss: Rom-Com Finale Arrives
Finale: December 29, 2025 | New Episodes: Wednesdays & Thursdays
Closing out 2025 is the finale of this romantic comedy about workplace deception and unexpected attraction. Jang Ki Yong and Ahn Eun Jin navigate the chaos when a kiss leads to mistaken assumptions about marriage, children, and office romance.
Ko Da Rim lied about her personal life to secure employment, claiming to be a married mother. When she impulsively kisses her team leader Kong Ji Hyuk, he assumes he’s involved with a married woman, creating comedic misunderstandings that drive the 14-episode series.
Weekly episodes continue through December, giving fans regular rom-com doses during the holiday season. The finale promises resolution to the deception and acknowledgment of genuine feelings brewing beneath the lies.
Why December 2025 Matters for K-Drama
