'Cashero': Lee Jun-ho takes on role of superhero whose powers cost him money

Global streaming giant drops 'Cashero' on December 26, introducing audiences to the world's stingiest superhero whose powers literally cost him every won he owns. Actor Lee Jun-ho transforms into Kang Sang-woong, a government employee scraping together marriage funds who discovers his strength multiplies based on how much cash he's physically holding, creating the ultimate financial dilemma when evil threatens humanity, according to Yonhap News reports.Sang-woong's supernatural ability comes with a brutal trade-off: every punch thrown, every bullet caught, every villain defeated literally burns through his money like gasoline. The teaser poster shows him clutching disintegrating bills with the haunted caption "What do I do? They want me to do good deeds while spending my own money," perfectly capturing the existential dread of sacrificing rent payments to save strangers. Unlike Marvel's billionaire Tony Stark or DC's wealthy Bruce Wayne, Sang-woong must choose between stopping crime and eating dinner, making him the most relatable superhero ever conceived.Director Lee Chang-min of 'The Vow' and 'Agency' adapts the hit Webtoon with a murderer's row cast including Kim Hye-joon as Sang-woong's girlfriend Min-sook, who watches her boyfriend's wallet empty with each heroic act. Lee Chae-min and Kang Han-na portray siblings Jonathan and Joanna, mysterious figures hunting superhumans for unknown purposes, while Kim Byung-chul appears as a supernatural lawyer and Kim Hyang-gi as another powered individual named Bang Eun-mi. The teaser shows Sang-woong demonstrating his abilities to a skeptical Min-sook before staring at his empty wallet in pure agony, followed by action sequences where he catches flying bullets while internally calculating the cost.Lee Jun-ho chose 'Cashero' as his first original lead role on the platform following three consecutive broadcast hits, gambling that this genre-bending "life-oriented my-money-my-power hero story" can rewrite superhero conventions. The series positions itself against Hollywood's endless parade of invincible, well-funded champions by asking what happens when heroism requires actual personal sacrifice beyond dramatic speeches. With promotional taglines like "My salary just passes through my bank account and today the things I need to spend money on never end," the show weaponizes millennial and Gen Z financial anxiety into what could become the year's most viral phenomenon.
