The title "Cashero" is a blend of “cash” and “hero.” Outside of some regions, it goes by the name Cashman or “Cash Hero” (現金英雄) when presented in Chinese. Kang Sang-woong gains an ability from his father; his strength increases with the amount of money he possesses, though that money vanishes whenever he uses his power. Living a typical life as a government employee and planning for marriage and owning a house, he finds himself pulled between those everyday concerns and his heroic duties while confronting a group trying to take what makes him special. Adapted from a well-liked webtoon, this action comedy series features heartfelt conversations and narration—it’s something I'd recommend checking out.
