One of the most anticipated K-dramas of 2025, Cashero revolves around a world where ordinary people can possess supernatural powers — but with a twist. The strength of each individual is determined by their own unique limitations, making their lives both complicated and thrilling.
Story Overview
Kang Sang Ung, a dedicated public servant, has superhuman strength that grows or weakens based on the amount of cash he carries. The more money he has, the more powerful he becomes — a concept that adds humor, tension, and depth to the story.
Despite his financial struggles, his girlfriend Kim Min Suk is supportive and grounded, helping him navigate the challenges of maintaining his unusual power.
Other key characters include:
- Byeon Ho In, a charismatic lawyer who leads a supernatural organization
- Bang Eun Mi, a telekinetic whose abilities depend entirely on her calorie intake
Together, they face dangerous threats and villains who seek to disrupt the balance of society.
Why Fans Are Excited
There has been a lot of speculation around the release date because Netflix may avoid clashing with large global releases like Stranger Things. Whether the show drops just before Christmas or gets pushed into early 2026, the hype continues to grow.
