Netflix Review: Cham Gyoyuk — More Addictive Than Bitter Americano
Top 10 in 85 countries, #1 in 19. This is not a corporal punishment fantasy — it is a longing for someone who refuses to give up.
Espresso is bitter and intense. The first time I watched Italians drinking nothing but espresso and decided to follow suit, I nearly spit it out. The kick is something else — consciousness arrives immediately, eyes snap open. Watching Netflix's Cham Gyoyuk (True Education), I kept thinking of that first espresso. Eyes wide open. Bitter. The show landed in the top 10 in 85 countries and hit number one in 19. Why does this distinctly Korean school fantasy grip adults who are long past graduation? Is it the punishment scenes? Or is it the imagination of punishment being possible at all?

Japan Wrote the Grammar — But This Is a Different Story
School-set dramas belong to Japan by precedent. Works dealing with ijime (bullying) appeared in novels, manga, and anime decades ago. What made Cham Gyoyuk work in a global market was that it borrowed Japanese genre grammar while running on entirely different fuel. The structure — violence, catharsis, a hero — looks familiar, but the underlying narrative is really about two men finding opposite ways to take revenge on the world.
The universality angle makes it even clearer. School violence, erosion of teacher authority, cyberbullying: these have become simultaneous social problems not just in Korea but across the US and Europe. Researching for this piece, I found that a teacher in Malaysia said they found comfort in this show. The feeling that "schools are falling apart" does not respect borders.
It's Not About Corporal Punishment — It's About Justice
What's interesting is that corporal punishment is the show's central mechanism. In an era when 156 countries have banned school corporal punishment, a protagonist who wields it — a teacher, no less — was welcomed. This is less about endorsing corporal punishment than it is about justice.
People want an eye for an eye. When law and institutions fail to punish perpetrators justly, audiences dream of private vengeance that matches the offense in kind. Korean webtoons already spotted this market — works like Vigilante have been doing it for years. The point is that people seek catharsis in the extralegal, the beyond-the-system. Where Japanese school drama sat with the tragedy of broken relationships, Cham Gyoyuk wired that tragedy into action and retribution.
The Netflix platform effect is also real. The share of Korean-language content among Netflix originals jumped from 12% to 20% in a single year. Cham Gyoyuk follows the lineage of "K-social-critique" hits — Juvenile Justice, The Glory. Good Korean content already has a global audience waiting for it.
How Far Has Teacher Authority Actually Fallen?
Curious, I called a teacher friend. The answer: half true, half exaggerated. There are genuinely problematic parents and genuinely problematic teachers out there, but the show amplifies.
Looking at the data: infringements on educational activity in Korea have been rising consistently since 2016, with a pandemic dip in 2020 followed by a doubling the year face-to-face classes resumed — a record high. In polling, half of respondents named parents' "my-child-first" mentality as the top cause of teacher authority violations. And in actual recorded violations, parents accounted for 71% of perpetrators. The mix: no legal mechanism to stop parents from violating teachers' rights, a tilt in the balance between student rights and teacher authority, and accumulated distrust of public education.
What surprised me is that this doesn't seem to be Korea's structural problem alone. Korea and Japan share the dynamic of parental credentials outpacing teachers', over-protection of fewer children, and a psychology of not wanting children to endure the authoritarian education parents themselves suffered. America arrives at a similar outcome via completely different causes: low pay, low social regard for teachers, mass departures post-COVID. Twenty percent of US teachers leave within five years of being hired. Student-on-teacher assault is no longer surprising news. Same headline — "teacher authority in collapse" — grown from opposite soil.
Why Parents Became Like This. Why Teachers Retreated.
I thought about the dynamic of military service: the soldier who was hazed by seniors tends to pass that resentment down to juniors. In schools, this cycle gets tangled. Parents who experienced the injustices of their own education try to prevent their children from going through the same — and in doing so, direct their aggression at schools and teachers. "I endured it, but my child absolutely will not" becomes preemptive control, excessive involvement.
Previous generations loved their children too. But the arithmetic is different when you have one or two children instead of many. Everything about that child becomes tied to the parent's sense of personal success or failure. Small setbacks for the child can no longer be tolerated.
Teachers' position has shifted entirely as well. When schools were the only path to university entrance, teachers were irreplaceable. Now private tutoring academies produce faster, more measurable results. Authority comes from dependency — "this person cannot be substituted" — and teachers have lost that foundation in the domain of academic outcomes. The collapse of teacher authority is not a moral failure. It is the vacuum left by being outcompeted.
Na Hwa-jin Takes Responsibility to the End
A teacher whose authority has eroded struggles to manage student behavior. Every intervention carries the risk of complaints and legal exposure. The rational response is to perform only the minimum required. But when parents and students feel "the teacher doesn't care," trust falls further and complaints multiply — a downward spiral.
This is exactly where Cham Gyoyuk lands. The real teacher has burned out and stepped back. The fictional Na Hwa-jin intervenes until it's finished. What audiences feel is not the pleasure of revenge so much as a vicarious satisfaction in an authority figure who does not quit. The reason we are drawn to this rough, improbable story is not catharsis through violence. It is the imagination of someone staying responsible to the end.
The Korean Teachers and Education Workers Union criticized the show for presenting corporal punishment and rights violations as natural solutions, and for framing student rights and teacher authority as opposed. Some noted that the racial and gender controversies in the original webtoon carried into the adaptation. The counter-argument is that drama isn't documentary — that the student-rights-versus-teacher-authority framing already existed in Korean education discourse before this show created it. But the moment the Gyeonggi province education superintendent mentioned the show and suggested examining its premise for real-world applicability, calling it pure fiction became untenable.
Same Problem, Different Approach: Black Dog
Black Dog covers the same collapse of teacher authority, but resolves it entirely differently. There is an episode — "Seong-suni bought two pieces of fruit" — in which a student raises a challenge about an exam question. When viewers were polled on whether the student's objection was a legitimate right or an overreach, it split exactly 5-5. That's the point: the show asks a question and lets it sit. Cham Gyoyuk doesn't do ambiguity. Villains are fully villainous; the protagonist's solutions are close to omnipotent.
Black Dog is a drama that lingers. Cham Gyoyuk is a drama that strikes immediately. The irony is that even within the cathartic revenge genre, Cham Gyoyuk ended up generating controversy and debate — not by design, but as a reaction from audiences who found the justification for the punishment too crude to accept without questioning.
Does the World Need Cham Gyoyuk?
Policy is already moving. The Ministry of Education redefined teacher complaint handling as an institutional responsibility and doubled the number of Educational Activity Protection Centers. Starting with the 2026 academic year, records of school violence will be mandatory considerations in all university admissions. These are necessary steps for teacher protection. But they absorb conflict into systems rather than eliminating the source. The underlying causes — credential inversion, private tutoring supremacy, parental over-investment — remain untouched.
Whether schools can escape the exam-centric track in the medium term, I genuinely don't know. That education policy is tied directly to national competitiveness can be seen in China's trajectory and in the shorthand "China obsessed with engineering, Korea obsessed with medicine." You can't design a country's future while leaving its schools behind.
In that sense, Cham Gyoyuk was a drama with the kick of espresso — a new kind of jolt. Espresso isn't addictive because of its bitterness. It's addictive because that bitterness wakes something up. What Cham Gyoyuk held us with wasn't punishment or retribution. It was the simultaneous awakening of the feeling that things cannot stay as they are. You don't have to agree with the methods. That it generated the conversation at all was enough.
