Netflix’s upcoming year-end flagship series 'Cashero,' starring Lee Jun Ho, is set to premiere on December 26—and anticipation is already skyrocketing.
On December 1, the platform unveiled the teaser poster along with a one-minute teaser video, immediately triggering a wave of excitement across online communities and social media. Despite being released only moments earlier, the preview drew rapid global reactions such as “the casting is insane” and “I’m already hooked,” signaling intense interest from viewers at home and abroad.
The series follows Sang Woong (played by Lee Jun Ho), a civil servant struggling to save up for marriage and a home, who suddenly gains a superpower that grows stronger with the amount of cash he’s holding. But there’s a twist—every time he uses his power, the money in his hand disintegrates like dust. Adapted from a popular webtoon of the same name, Cashero blends comedy and grounded realism to explore a world where “money literally becomes power.”
The teaser poster leaves a striking impression. Sang Woong, staring helplessly at cash slipping through his fingers, encapsulates the irony of a man who can’t freely use his newfound abilities. The poster’s tagline—“What am I supposed to do? They want me to do good deeds with my own money”—perfectly sums up the conflict faced by an ordinary office worker who suddenly becomes a “cash-based hero.”
Teaser Already Goes Viral: A Relatable, Penny-Pinching Hero Concept Shakes Up Viewers
The newly released two-minute teaser quickly and clearly establishes the series’ unique universe. In one scene, Sang Woong explains to his girlfriend Min Sook (played by Kim Hye Jun) that he gains power from holding money, only to lose that money the moment he uses the ability—an explanation delivered with brilliantly comedic timing. His humorous comparisons, like “gochujang versus cho-gochujang” and “fly versus fruit fly,” capture the lighthearted wit of the original webtoon.
Action scenes follow, showing Sang Woong catching flying bullets with one hand—an undeniably heroic moment. Yet just as he taps into his power, he panics about the cash disappearing, moving cautiously to avoid unnecessary use, balancing hilarity with sharp relatability. His final line in the teaser—“My salary just brushes past my bank account, and there’s always something new to spend money on”—resonates strongly with younger generations, amplifying the buzz.
Lee Jun Ho’s Ongoing Hot Streak Continues With His First OTT Superhero Role
The excitement also ties into Lee Jun Ho’s recent string of major hits. Since completing his military service, he has delivered consecutive ratings successes with MBC’s 'The Red Sleeve' (peaking at 17.4%), JTBC’s 'King the Land' (13.8%), and most recently tvN’s 'Typhoon Family' (10.3%). Now making his debut in a grounded, everyday-life superhero narrative—and his first Netflix original lead role—Cashero is widely expected to continue his streak.
Lee Jun Ho plays Kang Sang Woong, a paradoxical hero whose abilities rely entirely on how much cash he has in hand. Because his money evaporates each time he uses his strength, the concept injects a refreshing sense of realism rarely seen in superhero stories. Viewers are eager to see how Lee Jun Ho navigates the comedic and action-driven elements with his trademark charm.
Kim Hye Jun, Kim Byung Chul, and Kim Hyang Gi Form a Cast that Viewers Already Trust
The casting lineup is one of the main reasons audiences are calling it “unbelievable.”
Kim Hye Jun stars as Sang Woong’s longtime girlfriend Min Sook, a woman with a strong knack for numbers. Her efficiency-driven personality becomes clear the moment she realizes her boyfriend’s power relies on cash—pulling out a calculator before offering heartfelt support.
Kim Byung Chul plays “The Lawyer,” a superpowered individual whose abilities activate when he drinks. He leads the Korean Association of Superpowered Individuals, clashing with an opposing group called The Ordinary Humans Association, which hunts superhumans. He becomes a key figure who invites Sang Woong to help save the world.
Kim Hyang Gi transforms into Bang Eun Mi, who unleashes telekinesis based on the calories she consumes. With her quirky concept—fighting not on “rice power” but “bread power”—she brings bold, comedic energy to the story.
The series is directed by Lee Chang Min of Eulachacha Waikiki and Agency, known for his sharp comedic touch and grounded storytelling. Writers Lee Jae In and Jeon Chan Ho of Sisyphus: The Myth join forces to construct the show’s unique world.
Early Reactions Explode: “Fresh,” “Already Funny,” “This Casting is Unreal”
Within moments of the teaser’s release, social platforms were flooded with comments like “This is so fresh,” “How is a superhero show this relatable?”, “Lee Jun Ho’s casting is truly insane,” and “This already looks great.” Many praised the clever blend of real-world financial pressures and supernatural abilities, calling it a story that perfectly reflects today’s economic anxieties but with humor and creativity.
As Netflix positions 'Cashero' as a major title in its final quarter lineup, the excitement is rapidly spreading internationally as well. Shortly after the teaser dropped, fans across Asia began expressing strong anticipation for Lee Jun Ho’s superhero debut.
With its innovative “everyday-life superpower” concept and standout cast centered on Lee Jun Ho, Cashero is poised to shake up the year-end OTT landscape. And judging from the explosive reaction to the teaser alone, all eyes are now on how far this series will go once it officially premieres.
