Cashero is arguably the most awaited K-drama of late 2025. Fans have been buzzing about this superhero-style Korean drama for months, and anticipation continues to grow.
There are strong rumors that Netflix may release Cashero close to Christmas 2025. However, because Stranger Things is also scheduled for December, industry insiders believe Netflix may shift Cashero to late December or early January 2026.
Plot Summary
The series follows Kang Sang-Ung, a hardworking public servant gifted with an unusual power — his physical strength increases depending on how much money he has.

He isn’t alone.
