After striking a deal with Wylab, the K-drama adaptation of the popular webtoon Get Schooled is coming to Netflix. Previously titled True Lessons, the series has finally been confirmed as Teach You a Lesson. The K-drama will be released on Netflix on June 5, 2026. Here’s what we know so far.

Teach You a Lesson (previously titled True Lessons) is an upcoming South Korean Netflix Original action K-drama series, adapted from the popular webtoon of the same name by author Chae Yong Taek and illustrator Han Ga Ram. It will be directed by Hong Jong Chan and written by Lam Nam Gyu.

The webtoon was at the center of a large controversy in 2023 when the 125th chapter featured a racial slur aimed at one of its mixed-race characters. Naturally, we expect screenwriter Lam Nam Gyu to avoid racial slurs in the Netflix adaptation.

What is the plot of Teach You a Lesson?

The synopsis for Teach You a Lesson has been sourced from MyDramaList:

“Tells the story of students, parents, and teachers. In a society where teachers’ rights have fallen due to students who cross the line, parents who don’t know the line, and teachers who draw the line, the drama introduces adults who are not afraid of children and tries to properly teach children what they did wrong. Na Hwa Jin is a field supervisor at the Teachers’ Rights Protection Agency. He is a hexagonal person with perfect mentality, physicality, and brains, and is the designer of all the plans for the Teachers’ Rights Protection Agency. He is also called the ‘Grim Reaper’ because he is not afraid of absurdity, fear, or compromise, but he is a character who struggles to protect justice and peace.”
