On June 16, Netflix Korea uploaded a video titled “Teach You a Lesson Graduate Gathering: Villains Read Comments, Q&A, and Behind-the-Scenes Stories.” The video featured cast members Jang Yo-hoon, Ok Jin-wook, Yoo Tae-joo, Park Seo-yoon, and Park Ji-yeon, who reflected on their experiences filming the series while reacting to fan comments.

In Teach You a Lesson, Jang Yo-hoon delivered a memorable performance as a juvenile offender involved in a series of serious crimes. His character participated in vehicle theft, drove without a license, vandalized public property, and even became involved in drug distribution. His convincing portrayal left many viewers believing he perfectly embodied the troubled teenager he played on screen.

However, the actor’s real-life story could not be more different. At 33 years old, Jang Yo-hoon has earned praise not only for his acting talent but also for his academic achievements, leading many Korean netizens to label him an “eomchinah”—a Korean term referring to someone who excels in nearly every aspect of life.

Jang Yo-hoon graduated from Hyundai Chungun High School, one of South Korea’s well-known academic institutions. He later enrolled at Sungkyunkwan University, one of the country’s most prestigious universities. However, after completing his first year, he made the bold decision to leave and pursue his passion for acting. The actor subsequently entered the Korea National University of Arts, where he studied in the Department of Acting and focused on building his career in performance. The revelation surprised many fans who had only recently discovered him through Teach You a Lesson.

Following the disclosure of Jang Yo-hoon’s educational background, online communities quickly filled with reactions from impressed viewers. Some comments included:

  • His acting was so realistic that learning he attended Sungkyunkwan University is even more shocking.
  • He’s the definition of an ‘eomchinah.’
  • His performance in this drama was incredible. I hope to see more great acting from him in future projects.
  • His character was one of the worst people in the series, but his real-life personality seems completely different and charming.

The contrast between his intimidating on-screen presence and his accomplished academic history has only increased public interest in the rising actor.

Jang Yo-hoon’s growing popularity comes as Teach You a Lesson continues to dominate Netflix rankings worldwide. The drama follows the activities of a fictional Teacher Rights Protection Bureau, an organization established to restore authority and order in South Korea’s troubled educational system. The series tackles issues involving disruptive students, problematic parents, and challenges faced by educators, delivering what many viewers describe as a satisfying and cathartic form of justice.

After premiering on June 5, Teach You a Lesson reportedly reached the top of Netflix’s global rankings within just three days and maintained the No. 1 position for two consecutive weeks. The series also ranked No. 1 in 46 countries, including South Korea, Japan, and Brazil, while securing a place in the Top 10 rankings across 91 countries worldwide.

While many actors are praised for portraying heroes, Jang Yo-hoon has attracted attention for doing the opposite bringing a deeply unsettling villain to life with remarkable authenticity. Now, fans are discovering that behind the convincing performance is an actor with an impressive academic record and a dedicated commitment to his craft, making him one of the breakout stars to watch following the success of Teach You a Lesson.
