Is "Teach You a Lesson" Based on a Webtoon?

If “Teach You a Lesson” has been showing up everywhere since its June 2026 release, one of the most common questions about it is whether it’s based on a webtoon. It is — and knowing the source material helps make sense of the show without needing any spoilers.

The confirmed source material

“Teach You a Lesson” is based on “Get Schooled” (참교육, “Chamgyoyuk” — literally “real education”), a Naver webtoon by Chae Yong-taek and Han Ga-ram. The Netflix series follows an inspector from the Educational Rights Protection Bureau, a fictional government body authorized to use unconventional methods to intervene in delinquent-student cases — the same premise as the source webtoon. This is a confirmed production fact, not a fan theory: it’s stated directly on the show’s own listing and corroborated by its production record.

Why this is worth knowing

Korean film and television draw heavily on webtoons as source material — it’s one of the most common ways a hit show gets made, not an exception. Knowing a show is a webtoon adaptation tells you two practical things: there’s a completed, already-published story you can look up in outline (without this article spoiling it for you), and the official webtoon platform is the reliable place to go if you want more than the show gives you — not an unofficial scan or summary site.

What this article won’t do

This is a source-material confirmation, not a plot summary or a review. The source webtoon has drawn public discussion over how it portrays school discipline, and the show’s own director has spoken about approaching that material differently on screen — that’s a separate conversation from the simple fact of adaptation, and it’s not something a general confirmation piece is the right place to adjudicate. If you’re curious about that discussion, entertainment coverage of the show is where to look; this article stays with the one question in its title.

How adaptations like this generally work

If this is the first time you’ve run into a “based on a webtoon” credit, it helps to understand the broader pattern — how Korean webtoon adaptations work in general, why studios pick them, and how to find official source material for other shows.

Where to go from here

Once you know a show has a real, findable source, the next practical question is usually where you can actually watch it — official platforms and availability change by country, so it’s worth checking directly rather than assuming.
