Netflix’s Teach You A Lesson is facing criticism over a breast surgery line after viewers circulated screenshots of a scene referencing breast reduction surgery. The backlash has added a new flashpoint to the wider Get Schooled controversy around the drama, which was released on Netflix on June 5, 2026, after earlier objections to its source material and premise.12
The disputed line is delivered by a teacher character played by Jin Ki-joo. In the scene cited in the backlash, the character says, “Yeah, I got surgery. Breast reduction surgery.”1 Koreaboo reported on June 9, 2026, that the line drew intense criticism from viewers who saw it as misogynistic, while some online responses argued that public criticism was concentrating too heavily on one scene rather than the series as a whole.1
Breast Surgery Line Becomes New Focus

The current criticism centers on a sarcastic exchange involving Jin Ki-joo’s character and a reference to breast reduction surgery. The line became the subject of online discussion after screenshots from the Netflix drama spread among viewers.1 The available reporting identifies the controversy as a response to the wording and tone of the scene, rather than to a production statement or a formal complaint from a named organization about this specific line.
Teach You A Lesson is the English title associated with the Netflix series based on the Korean webtoon True Education, also known in English discussion as Get Schooled. Netflix previously announced the project under the working title True Lessons on March 20, 2025, naming Kim Moo-yul, Lee Sung-min, Jin Ki-joo and Pyo Ji-hoon among the cast.3 The official production announcement described the story as centered on a fictional Educational Rights Protection Bureau that intervenes when students, teachers or parents cross the line.3
That premise remains central to the latest debate. Dong-A Ilbo, reviewing the drama after release, described the story as following a fictional Teachers’ Rights Protection Bureau with extraordinary authority to punish students, teachers and parents who disrupt schools.2 The review also noted that the adaptation removed some disputed elements from the webtoon, including racism-related material, but said the broader framework of justifying physical force remained open to criticism.2
Earlier Objections Framed The Series Before Release
The breast surgery line controversy did not emerge in isolation. Before the Netflix release, Teach You A Lesson had already faced public objections tied to the original webtoon’s themes and the drama’s premise. Chosun Edu reported that the Korean Teachers and Education Workers Union held a press conference outside Netflix Korea on July 23, 2025, calling for production of the drama to stop.4
The union objected to the project on the grounds that the source material framed corporal punishment and violence as responses to school problems and included hateful or violent expression.4 Kim Ji-yeon, a KTU vice chair, was quoted at the press conference as saying, “Hate and violence can never be freedom of expression.”4 That criticism placed the production under scrutiny months before the current debate over the breast reduction surgery line.
Netflix’s own March 2025 announcement presented the series as a story about intervention in school conflicts through the fictional bureau. Jin Ki-joo was quoted in that release as saying, “Firmly grounded in today’s reality, the script is so compelling.”3 The contrast between the official framing and later criticism has shaped the public discussion around whether the series functions as social commentary, provocation, or endorsement of punitive solutions.
Dispatch reported on May 20, 2026, that Netflix had released the main poster and trailer for Teach You A Lesson, describing the series as based on the popular webtoon of the same name and following a Teachers’ Rights Protection Bureau confronting students and parents who cross boundaries in schools.5 At that time, the release was scheduled for June 5, 2026.5 By June 8, 2026, Dong-A Ilbo was reviewing the drama after its release, confirming that the public debate had moved from production concerns to the finished series.2
Chart Performance Amid Backlash
The controversy has unfolded alongside strong viewing performance. ZAPZEE reported on June 8, 2026, that Teach You A Lesson rose from No. 5 to No. 3 on Netflix’s global TV chart shortly after release and reached No. 1 in 25 countries.6 The outlet also summarized the project’s difficult road to release, citing prior criticism of the original webtoon over racist and hateful expressions and earlier concern from a Korean teachers’ union.6
Those figures show that the drama’s visibility expanded quickly even as criticism continued. The available sources do not show an official Netflix response to the specific breast surgery line, nor do they report a production change connected to the current backlash. What is documented is a sequence of disputes: objections to the source material and premise in 2025, scrutiny of the adaptation’s handling of contested elements, and now criticism of a specific line involving breast reduction surgery after release.

The latest criticism over the Teach You A Lesson breast surgery line has therefore become part of a broader argument about how the series depicts authority, punishment, gendered language and school conflict. With the drama already released and ranking prominently on Netflix charts, the Get Schooled controversy now rests on both its long-running source-material disputes and viewer reaction to scenes in the finished adaptation.
