Netflix original series 'Teach You a Lesson' is continuing its explosive global run, rewriting the streamer’s rankings in the process. Since its debut, the Korean drama has rapidly built momentum with viewers worldwide, and in its third week of release, it once again held firmly to the top spot—cementing its breakout status as a full-fledged phenomenon.
According to Netflix’s global rankings released on June 24, 'Teach You a Lesson' recorded 11.8 million views and 126.2 million viewing hours for the week. Netflix defines views as total viewing hours divided by a title’s runtime. With that, 'Teach You a Lesson' successfully defended its No. 1 position on the Global Top 10 Non-English TV chart for a third consecutive week.
Its performance has been dominant across both domestic and international markets. The series ranked No. 1 in 19 major Asian markets, including South Korea, Vietnam, Taiwan, Singapore, the Philippines, and Malaysia, while also landing in the Top 10 in a total of 85 countries worldwide. In South Korea, it has maintained the No. 1 spot on the “Top 10 Series in Korea Today” chart without losing the position even once since its release.
Its weekly numbers make the scale of its success even clearer. The drama opened with 6.4 million views in its first week, surged to 21.1 million views in week two, and added another 11.8 million views in week three, bringing its cumulative total to 39.3 million views so far.
Fueled by that momentum, 'Teach You a Lesson' is also shaking up the all-time rankings for Netflix Korean original dramas. By reaching 39.3 million views in just three weeks, it has already overtaken 2021 drama 'My Name,' which previously held the No. 6 spot with 29.4 million views, and has now claimed sixth place on Netflix’s all-time Korean drama rankings.
At present, the top Netflix Korean original dramas are led by 'Squid Game' Season 1 with 265.2 million views, followed by Season 2 with 192.6 million, Season 3 with 145.8 million, All of Us Are Dead with 55.5 million, and The Glory with 39.7 million. With only a 400,000-view gap separating 'Teach You a Lesson' from 'The Glory,' the series is widely expected to move into the Top 5 very soon. As its momentum shows no signs of slowing, industry attention is now turning to just how far 'Teach You a Lesson' can climb.
Based on the hit webtoon of the same name, 'Teach You a Lesson' is an action drama centered on the Educational Rights Protection Bureau, a government body that works to restore collapsed school authority, stand up for victims of school violence and campus crimes, and bring order back to schools. The adaptation transforms the webtoon’s established world-building and satisfying revenge-driven narrative into a polished screen production, backed by director Hong Jong Chan’s stylish direction and writer Lee Nam Gyu’s tightly constructed script. The show’s distinct, vividly drawn characters—brought to life by a committed cast—have also been cited as one of its biggest draws.
At the center of the series is Na Hwa Jin, played by Kim Moo Yeol. A former special forces operative who now serves as a supervisor in the Educational Rights Protection Bureau, Na is portrayed as the most formidable figure in the drama’s universe. He tackles corruption, violence, and dysfunction in schools with his own direct and uncompromising methods. Though he projects a cold and intimidating presence on the outside, he is deeply compassionate at heart—always siding with victims, listening to their stories, and offering genuine care.
The live-action version of Na preserves the webtoon character’s reputation as a near-invincible “human weapon,” formerly of the elite 707 Special Mission Group and one of the unit’s top close-combat fighters. The drama leans fully into that image, showing him effortlessly overpowering multiple adult men and displaying not only hand-to-hand combat skills but also expert knife-fighting ability.
Lee Sung Min plays Choi Kang Seok, the education minister who founded the Teacher Rights Protection Bureau and serves as one of the drama’s central pillars. As political opponents and other forces attempt to dismantle the organization over its unconventional methods, Choi forcefully defends the bureau’s purpose and the true meaning of protecting teachers’ rights. He acts as a powerful shield behind the scenes, blocking political pressure and allowing Na Hwa Jin and the other supervisors to do their jobs without hesitation.
In the original webtoon, Choi is depicted as a heavyweight political figure—a six-term lawmaker with 26 years of political experience and a former party leader. The drama scales the character down somewhat by making him the education minister, a change that grounds the story in a more realistic framework and strengthens its plausibility.
Jin Ki Joo plays Im Han Rim, Na Hwa Jin’s junior from the special forces and a fellow bureau supervisor. She is one of the adaptation’s most striking reinterpretations. At first glance, Han Rim appears refined and innocent, but she quickly reveals herself to be fearless, blunt, and impossible to control, constantly surprising those around her. She is unwavering in her beliefs and pushes forward with fierce determination, sometimes to the point of seeming inflexible, but her sincerity toward victims is unquestionable.
While the webtoon version of Im Han Rim balanced a short temper with a generally calm and composed personality, the drama reimagines her as a more eccentric and impulsive character with a stronger offbeat edge. Her military background is also emphasized more heavily, to the point that she still speaks in a rigid military-style tone even in everyday situations.
'Teach You a Lesson' is also dominating buzz rankings that measure public conversation and audience response. According to FUNdex, the popularity index run by Korean content analytics firm Good Data Corporation, the drama rose to No. 1 in the integrated TV and OTT drama category just two weeks after release.
By its third week, not only the series itself but also its lead actors had climbed into the upper ranks of the buzz charts, reflecting the show’s sustained popularity. Analysts say the drama’s strong resonance comes from the way it confronts very real social issues—such as school violence, the erosion of teachers’ authority, and juvenile crime—while delivering the material with the cathartic payoff of a genre series.
The show’s impact has now extended beyond entertainment, drawing attention from both the political sphere and the education sector. Discussions have reportedly begun in the National Assembly over whether a real-life version of the Teacher Rights Protection Bureau—currently fictional in the drama—could be implemented in some form.
A policy forum titled Why and How to Create a Gyeonggi Office for the Protection of Educational Activities is set to be held at the National Assembly Members’ Office Building. The event is being framed as the first official forum designed to explore concrete legal and institutional frameworks to strengthen teachers’ rights and protections, amid a sharp rise in public attention surrounding the issue following the global success of 'Teach You a Lesson.'
The forum will feature in-depth presentations aimed at developing a roadmap for restoring order to struggling school environments and ensuring safe working conditions for teachers. The keynote presentation will be delivered by teacher Kim Se Joon of Gugal Middle School under the theme Why Schools Need a Gyeonggi Office for the Protection of Educational Activities Now, offering a firsthand look at the realities facing schools on the ground.
As 'Teach You a Lesson' continues to dominate, other Korean dramas on Netflix are also benefiting from the momentum. SBS drama 'My Royal Nemesis,' which is currently available on Netflix after its television run, recorded 2.7 million weekly views and ranked No. 6 on Netflix’s global non-English chart for the fourth week of June, proving its continued appeal with viewers.
One of the most notable ripple effects, however, has been renewed interest in director Hong Jong Chan’s previous work. His 2022 Netflix original Juvenile Justice has seen a sharp resurgence in global viewership thanks to 'Teach You a Lesson’s success. The series drew 1.2 million weekly views and re-entered the Global Top 10 at No. 10, showing strong reverse-charting momentum. By bringing renewed attention to a previous project already praised for its social message and weighty direction, 'Teach You a Lesson' has once again reinforced Hong’s reputation as a hit-making director.
With stylish action, compelling characters, and a weighty social message that forces viewers to confront real-world issues, 'Teach You a Lesson' has assembled all the ingredients of a global smash. Attention is now focused on how long it can remain at the top of Netflix’s worldwide rankings—and whether the drama’s impact could help shape the future of South Korea’s education system.
