The Netflix drama Teach You a Lesson is gaining global attention not only for its intense storyline about school violence but also for the powerful real-life impact of its cast, especially rising actor Lee Seung Gyu, whose recent actions have extended the showâs message far beyond the screen.
In the series, Lee Seung Gyu appears in the opening episode as Ryu Jun Hyung, a chilling antagonist who embodies the cruelty of privilege and unchecked power. His character is the son of a presidential hopeful lawmaker, Ryu Gwang Pil, and uses his social status to intimidate and dominate his school environment through violence and manipulation.
The drama, written by Lee Nam Gyu, Kim Da Hee, and Moon Jong Ho, and directed by Hong Jong Chan, quickly established itself as a hard-hitting exploration of systemic abuse within the education system, blending emotional storytelling with social commentary.
Lee Seung Gyuâs performance left a strong impression on viewers, with many praising his ability to portray both cold-hearted cruelty and a shocking downfall. His portrayal was so convincing that audiences online nicknamed him âa handsome piece of trash,â reflecting both admiration for his acting and the hatred toward his character.
Beyond the screen, however, Lee Seung Gyu took the dramaâs message to heart in a meaningful way. He made a donation to the BTF Blue Tree Foundation, an organization dedicated to preventing school violence and supporting victims and their families.
The foundation itself is a deeply important institution in South Korea, focusing on education, prevention programs, and emotional support services for victims of bullying. It was established by Chairman Kim Jong Ki after the tragic loss of his child due to school violence, giving the organization a profoundly personal mission.
Lee Seung Gyu explained his motivation with emotional sincerity, stating, âI want to turn the pain I encountered through acting into real-world support. Even after the drama ends, I wonât forget.â His words resonated strongly with fans who praised his humility and awareness of the storyâs real-world relevance.
The drama is set in a fictional system where a government agency called the Bureau for the Protection of Teachersâ Rights is created to address cases of violence and injustice within schools. This framework allows the story to explore both institutional corruption and the emotional struggles of victims seeking justice.
Based on a popular webtoon, Teach You a Lesson expands its narrative by blending fictional storytelling with real societal issues, creating a narrative that feels both entertaining and socially impactful. The adaptation retains the emotional weight of its source material while elevating it for a global streaming audience.
According to Netflix Tudum rankings for June 8â14, the series reached No. 1 on the Global Top 10 Non-English TV Shows chart, accumulating 21.1 million views in a single week, highlighting its massive international success and resonance.
What makes the series particularly powerful is how it confronts the long-lasting effects of bullying, showing not only the immediate pain of victims but also the systemic failures that allow such behavior to persist. This message has clearly struck a chord with audiences worldwide.
Ultimately, Teach You a Lesson stands out as more than just a drama about school violenceâit has become a cultural conversation starter. With Lee Seung Gyuâs standout performance and his meaningful real-world contribution, the series reinforces its core message: that stories about pain can also inspire action, awareness, and change.
