Netflix just dropped the full official trailer for its wildly inventive superhero K-drama Cashero, and the premise is as simple as it is addictive: the harder you punch, the more money disappears from your bank account. Adapted from the hit webtoon by Lee Hoon and No Hye-ok, the eight-episode series follows an ordinary public servant who gains superhuman strength—at the literal cost of his paycheck.
The trailer teases the story of Kang Sang-woong (Lee Jun-ho), a debt-ridden security guard who unexpectedly inherits superhuman strength—complete with the quirky caveat that each burst of power deducts directly from his bank account. As he navigates a world of corporate intrigue and shadowy antagonists, one line stands out amid the chaos: "Someone I can't handle with my paycheck," highlighting the protagonist's wry frustration with foes beyond his budgetary reach. Directed by a team led by writers Lee Je-in and Jeon Chan-ho, the series explores themes of inequality and resilience through its "my money, my power" premise, setting it apart in Netflix's growing K-drama lineup.
Leading the ensemble is Lee Jun-ho, known for his versatile roles in hits like King the Land, who embodies the reluctant hero grappling with the literal cost of justice. Opposite him is Kim Hye-jun (*Nevertheless*) as Kim Min-sook, a sharp-witted ally in the fight against systemic corruption. The supporting cast adds layers of tension, including Kim Byung-chul (*When the Camellia Blooms*) as the enigmatic Byeon Ho-in, and Kim Hyang-gi (*The Uncanny Counter*) as the determined Bang Eun-mi.
Adding intrigue to the villainous roster is Kang Han-na, stepping back into antagonistic territory after her memorable turn as a cunning schemer in the fantasy romance Bon Appetit, Your Majesty. Her portrayal of Joanna promises a sophisticated threat, leveraging intellect over brute force. Intriguingly, Lee Chae-min—the breakout star from that same series, where he charmed as a devoted lead—reunites with Kang Han-na but trades tenderness for treachery, appearing as the calculating Jonathan in what trailer glimpses suggest is a pivotal adversarial role.
Coinciding with the trailer's debut, Netflix released a striking new poster featuring dual versions in English and Korean, capturing the ensemble in gritty urban shadows amid cascading coins and bold typography that evokes the series' monetary motif. The visuals underscore the theme of ordinary individuals wielding "cash heroism" against overwhelming odds, with Lee Jun-ho's hooded figure front and center, exuding quiet intensity.

Filmed primarily in Incheon, South Korea, Cashero marks Netflix's continued investment in webtoon adaptations, following successes like Sweet Home and All of Us Are Dead. With its release timed for the holiday season, the series positions itself as a fresh, binge-worthy escape blending pulse-pounding action sequences with poignant commentary on modern financial pressures.
Cashero will stream globally on Netflix starting December 26, 2025, with all episodes available from launch day for subscribers worldwide. In the lead-up to the premiere, new stills were recently released, offering glimpses of Lee Jun-ho and Kim Hye-jun embodying the grounded heroism at the story's core.
