Kim Mu-yeol stars in Teach You a Lesson, the Netflix K drama that narrowly outperformed One Piece in the platform's first half of 2026 viewing report, released July 16. Teach You a Lesson collected 48 million views from January through June, edging out One Piece's 47 million views. The series premiered June 5, 2026, nearly three months after One Piece season 2 debuted, yet it quickly dominated Netflix's charts throughout the following month. That kind of late arrival followed by an immediate streaming surge is exactly the sort of numbers-based plot twist fandom discourse tends to miss. How Did Teach You a Lesson Beat One Piece? Teach You a Lesson comes from returning creative staff associated with Juvenile Justice and centers on the fictional Educational Rights Protection Bureau. The organization draws inspiration from real debates about bullying, corruption, and abuse in South Korea's education system, then turns that premise into a violent revenge-driven thriller. Netflix's overall TV ranking for the first half of 2026 placed His & Hers at No. 1, Bridgerton at No. 2 with 100 million views, and Stranger Things season 5 at No. 4 with 56 million views. Teach You a Lesson did not approach Squid Game's global reach, but its 48 million views were enough to beat Netflix's live-action One Piece, proving that a buzzy K drama can break through beyond the platform's non-English charts.
