True education

Choi Kang-seok is the South Korean Minister of Education and the founder of the Teachers' Rights Protection Bureau (ERPB). His character combines iron will, steadfastness, and deep personal drama: Calm and Monumental: Compared to his eccentric and tough field agents (such as Na Hwa-jin), Choi Kang-seok stands like a rock. He possesses tremendous endurance, composure, and strategic thinking. Unwavering Leader: He takes full political and social responsibility for the radical and sometimes brutal methods of his Bureau. Kang-seok steadfastly withstands attacks from the press, officials, and the opposition, protecting his subordinates. Driven by Justice and Grief: His motivation is deeply personal. The creation of the Bureau is a tribute to the memory of his deceased daughter, Ga-yoon (who was a teacher and was killed by her own student). Because of this tragedy, he sincerely despises juvenile delinquents and those who ruin the lives of educators. Appearance
Style and Status: Unlike the original comic (where the character looked different in his youth), in the drama, Choi Kang-seok is presented as a respectable, mature, and influential older man. Clothing: He always looks impeccable, presentable, and strict. As a high-ranking politician and minister, he wears expensive, classic three-piece business suits, perfectly ironed shirts, and ties. Facial Features and Charisma: He has the insightful, heavy, and wise gaze of a man who has endured enormous trials in life. His short, neat gray haircut and stern facial features emphasize his authority, his status as an "eminence grise," and his steadfastness in the face of the system's enemies.

Bong Geun-dae is a brilliant civil servant and the administrative deputy manager at the Teachers' Rights Protection Agency (ERPA). He graduated early from KAIST (Korea's prestigious Advanced Institute of Science and Technology), which speaks to his exceptional intellect. Eccentric and a bit awkward: At first glance, he may seem eccentric, fidgety, naive, and even a little frivolous. He often serves as the show's comic relief. Expert: Despite his comedic exterior, Geun-dae is a top-notch specialist and an outstanding hacker. When it comes to work, gathering dirt on school gangs, searching for information, and hacking systems, he acts quickly and flawlessly. Voice of the Viewer: For the audience, he is a guide into the world of the Agency. Through his eyes, the viewer sees the harsh, sometimes extreme methods of the chief inspectors (such as Na Hwa-jin). At the same time, Geun Dae is loyal to his team and sincerely fights for justice.
Since Pyo Ji Hoon (PO) plays the role, the character has a very bright and charismatic appearance: Clothing style: Since he is an office worker and a tech specialist, his style combines elements of formal and casual (smart-casual). He can often be seen in loose shirts, jackets, cardigans, or hoodies, which emphasize his slightly geeky, yet neat status. Hairstyle and face: He has a classic Korean textured haircut with bangs. The actor has very mobile, lively facial expressions - he easily switches from a hilariously confused expression to maximum concentration when he sits down at the keyboard. Overall impression: He appears as a friendly, good-natured, slightly clumsy guy "from next door", who dramatically transforms when it comes to large-scale hacking attacks for the sake of saving teachers and students. And he was in love with Im Han Rim

Han Rim's character is built on a stark contrast between her outward restraint and her fiery inner temperament. She can be described as an "unstoppable force of justice." Explosive and fearless: Han Rim has absolutely no tolerance for injustice, violence, and bullying in schools. She acts tough, straightforward, and unhesitatingly confronts both school gangs and corrupt officials. Professional and military-trained: As a former special forces sergeant, she possesses nerves of steel in crisis situations. Her demeanor and manner of speech reflect the manners of a strict army instructor. She is disciplined and methodical. Loud and eccentric: The creators of the series imbued the character with unique traits—unpredictable behavior, eccentric, exaggerated mannerisms, and a habit of loudly, robotically barking orders—which distinguishes her from classic, cold-blooded action heroines. And she worked at Bono.

Appearance and Style: A tall, athletic man with rugged yet stylish features. He wears a neat short haircut and is often seen wearing formal yet practical dark suits or classic coats, emphasizing his official status as an inspector. Eyes: He has the piercing, cold, and confident gaze of someone who is completely unafraid of danger and sees right through people. Details: A slight, slightly ironic or predatory smirk can often be seen on his face before he springs into action. During fights, his movements are extremely precise, graceful, and devastating. Character Profile: Na Hwa-jin is a former special forces soldier and field inspector for the Ministry of Education, sent to schools to combat total chaos and brutal bullying. Uncompromising and Tough: He doesn't believe in soft talk with juvenile delinquents and believes that rampant violence can only be stopped by superior force. Ironic and Cynical: He possesses a sharp wit and dark humor. He often provokes bullies, forcing them to show their true colors before giving them a physical lesson. Just Protector: Behind his cold-blooded and cruel exterior lies a deep sense of justice. He sincerely defends weak students and teachers who have found themselves helpless in the face of the system. Confident and Fearless: Hwa-jin has absolute confidence in his abilities. He is uninhibited by the connections of his wealthy parents or the authority of street gangs.
