The Plot of Cashero: When Power Comes at a Price?
Adapted directly from Lee Hoon’s popular Naver webtoon, Cashero tells the story of Kang Sang Woong, an ordinary office worker who suddenly gains superhuman powers. But there’s a twist his strength is tied to how much money he spends. The more he spends, the stronger he becomes.
The premise offers a clever, satirical look at capitalism and modern life, turning financial sacrifice into literal strength. As Sang Woong tries to balance his newfound powers with his growing debt, he discovers that true heroism isn’t about wealth or glory it’s about selflessness.
The show follows multiple characters from government agents to rival superhumans as they grapple with the implications of a world where money can buy power, but not purpose.
Netflix Korea teased the storyline, saying:
“Cashero is a superhero story that asks one question: What if saving the world costs you everything you own?”
The blend of satire, fantasy, and social realism makes Cashero one of the most anticipated K-dramas of 2025.
Main Cast and Characters of Cashero
Lee Junho as Kang Sang Woong (Cashero)
K-pop idol and actor Lee Junho (2 PM) headlines the series as Kang Sang Woong, the titular “Cashero.” Known for his roles in King the Land and The Red Sleeve, Junho brings both charisma and depth to the conflicted hero who must spend money to save lives.
Netflix Korea’s production chief Jin Soo-yeon commented,
“Lee Junho embodies the essence of Cashero — a man burdened by morality, humour, and the absurdity of power tied to wealth.”
Kim Hyang Gi as Kang Sang An
Rising actress Kim Hyang Gi plays Kang Sang An, the protagonist’s younger sister a bright and determined college student who becomes his emotional anchor. Fans may remember her from Sweet Revenge, Moment at Eighteen, and Poong, The Joseon Psychiatrist.
This marks her second Netflix project following a brief cameo in Space Sweepers. In Cashero, Hyang Gi is expected to play a pivotal role as the voice of reason amidst the chaos.
Kim Hye Joon in an Unnamed Leading Role
Known for her chilling performance as the Queen in Netflix’s Kingdom, Kim Hye Joon takes on another complex role in Cashero. Her character remains under wraps, but early reports suggest she plays a government operative with a secret agenda involving superpowered individuals.
Having impressed audiences in Inspector Koo and Connect, Hye Joon’s return to Netflix signals another dynamic and unpredictable performance.
Kim Byung Chul as Byeon Ho In
Veteran actor Kim Byung Chul, known for his memorable turns in All of Us Are Dead and Doctor Cha, portrays Byeon Ho In, a scientist who becomes entangled in the Cashero experiments. His morally grey character will likely bridge the worlds of science and heroism, adding tension and wisdom to the ensemble.

Filming took place across Seoul and Busan, with large-scale action sequences reportedly shot using both practical stunts and CGI. Director Lee Chang Min shared his excitement in a behind-the-scenes interview:
“Cashero pushes the boundaries of K-drama production — it’s a mix of humor, social critique, and visual spectacle we haven’t seen before in Korea.”
The production team also collaborated with VFX studios from The Witch: Part 2 and Sweet Home to ensure world-class action design.
Themes and Expectations: A Superhero Story with a Korean Soul
Unlike typical Western superhero tales, Cashero centers on ordinary humanity in extraordinary circumstances. Its satirical edge pokes fun at modern capitalism, showing how even superpowers can’t escape financial systems.
Cultural critic Ryu Dae-hoon noted,
“Cashero is not about saving the world — it’s about saving yourself from what the world demands.”
Netflix’s investment in Cashero also highlights its strategy to diversify K-drama genres, expanding beyond romance and thrillers into fantasy and sci-fi storytelling.
