Cashero

Financial hardship is a reality most people know all too well, but for Sang-Ung Kang, the burden of poverty comes with an extraordinary twist. He unexpectedly uncovers a dormant superhuman ability hidden deep within himself—one that operates under a bizarre and demanding condition. His physical strength and speed scale directly with the amount of money he possesses. The more cash he holds, the more powerful he becomes, turning wealth into literal might. However, this remarkable gift offers no easy escape from his struggles; without sufficient funds, his potential remains entirely locked away. Determined to change their circumstances, Sang-Ung teams up with his sister, Sang-An, to navigate the daunting challenge of keeping themselves financially stable. Together, they must devise a strategy to generate enough income not only to survive but to actively fuel his newfound powers. Their ultimate goal is to find a way to monetize his abilities while strictly guarding his secret identity from the outside world. Balancing the constant need for cash with the perilous task of remaining anonymous proves to be a far more complicated endeavor than either sibling anticipated, forcing them into a high-stakes balancing act where every dollar counts toward their survival.
