“Teach You a Lesson” has just done something only one other Korean series has ever managed: crack Netflix’s all-time top 10 list for the most-watched non-English shows in the platform’s history. The action drama enters the chart at No. 10 with 60.2 million views, eight weeks after it first premiered, putting it in the same rarefied company as the Squid Game franchise.
A Historic Chart Entry for Korean Drama
Netflix’s all-time non-English chart has been dominated almost entirely by Squid Game since the category existed, with all three seasons of that franchise currently occupying the top three spots. Teach You a Lesson becoming just the second Korean title to break into that top 10 is a significant milestone, especially for a series that isn’t a follow-up to an existing hit and had to build its audience from a standing start after its June 5 premiere.
What Teach You a Lesson Is About
The series is based on the popular Naver webtoon “Get Schooled,” created by Chae Yong-taek and Han Ga-ram, and it exists in the same fictional universe as the 2025 series Study Group. The story follows Na Hwa-jin, an inspector for a government body called the Educational Rights Protection Agency, who is sent into problem schools with unusual authority to discipline delinquent students and confront school violence using methods well outside a normal teacher’s toolkit. Hong Jong-chan, who previously directed the acclaimed series Juvenile Justice, sits in the director’s chair, bringing a similar willingness to tackle youth-focused social issues head-on.
The Cast Behind the Record
Kim Moo-yul leads the series as Na Hwa-jin, joined by Lee Sung-min, Jin Ki-joo, and P.O in principal roles. The show runs 10 episodes and debuted at No. 1 on Netflix’s global rankings in its first week, a position it went on to hold for four consecutive weeks before settling into the sustained long-tail viewership that eventually pushed it past the 60 million view mark.
Why It Broke Through Where Other K-Dramas Haven’t
Plenty of Korean dramas have found international audiences on Netflix, but very few have managed the kind of durable, multi-month viewership required to challenge an all-time chart still dominated by a global phenomenon like Squid Game. Teach You a Lesson’s premise, an action-driven school drama built around a genuinely novel central concept, gave it crossover appeal beyond the core K-drama fanbase, closer to how a procedural or action thriller pulls in casual viewers who might not otherwise seek out subtitled programming.
What This Means for Korean Content on Netflix
Netflix has leaned heavily into Korean originals since Squid Game’s 2021 breakout, and Teach You a Lesson’s chart placement is a reminder that the strategy is still paying off well beyond that one show. For a title with no existing built-in fanbase from a prior season or franchise to land this high on an all-time list is a stronger signal of the format’s staying power than another Squid Game-adjacent hit would have been, since it shows Korean drama can still break through on its own terms.
How It Compares to Other Recent K-Drama Hits
Netflix has had no shortage of Korean drama success stories over the past few years, from workplace dramas to romance-driven hits that topped weekly charts around the world. What separates Teach You a Lesson is longevity rather than a single explosive opening week. Plenty of shows debut at No. 1 globally and fade within a couple of weeks once the initial release buzz wears off; this series instead held that top spot for a full month and kept accumulating views steadily enough afterward to still be climbing an all-time chart two months after its premiere, which is a much harder bar to clear than a strong opening alone.
