From brutal classroom hierarchies to delayed revenge: 14 best K-dramas about fighting school bullies like ‘Teach You a Lesson’

Park Ji-hoon stars as Yeon Si-eun in Weak Hero: Class 1, an academically top-performing student whose quiet, withdrawn presence initially makes him an easy target for school bullies. Physically unimposing, Si-eun does not rely on strength or intimidation. Instead, he uses observation, precision and quick decision-making to survive repeated attacks that escalate in intensity throughout the series.

The story traces how Si-eun gradually adapts to a hostile school environment, turning everyday objects and situational awareness into defensive tools. His approach to conflict is methodical rather than emotional, often anticipating patterns of violence before they fully unfold. This calculated style of resistance becomes the defining feature of his character as the threats around him grow more organised and dangerous.

Choi Hyun-wook plays Ahn Su-ho, a skilled fighter who becomes one of Si-eun’s earliest allies, while Hong Kyung appears as Oh Beom-seok, a transfer student whose involvement complicates the group’s dynamic. Their relationships shift as pressure builds, showing how alliances in a school dominated by school bullies can fracture under stress.

Rather than positioning violence as spectacle, the drama focuses on survival logic and the psychological toll of constant confrontation. It also highlights how school bullies operate not only through physical force but through hierarchy and group power, forcing Si-eun to rely on strategy as much as endurance.

The series is available on Netflix.

The Glory begins in the aftermath of high school violence, following Moon Dong-eun, played by Song Hye-kyo, as she rebuilds her life after enduring severe bullying in school. The early experiences that shape her trajectory are not shown as isolated incidents but as sustained abuse that alters her education, relationships and sense of safety, ultimately forcing her to abandon her original ambitions.

Years later, Dong-eun returns with a structured plan for revenge against the classmates who participated in or enabled the abuse. Rather than relying on spontaneous retaliation, she carefully maps out each target, identifying their vulnerabilities and building long-term strategies to dismantle their lives from within. The narrative gradually reveals how deeply interconnected the former group of school bullies has remained, even after leaving school, and how their past behaviour continues to influence their adult lives.

Lee Do-hyun plays Joo Yeo-jeong, a surgeon who becomes involved in Dong-eun’s plan and adds another layer of moral complexity to her pursuit. Lim Ji-yeon portrays Park Yeon-jin, the central antagonist whose life appears outwardly successful while hiding a history of violence. Park Sung-hoon and Yeom Hye-ran also feature as members of the original group, each reflecting different levels of complicity.

The drama shifts between past and present to show how school bullies leave long-term psychological and social consequences, not only for victims but also within the structures that allowed the abuse to continue. It is available on Netflix.

Pyramid Game adapts the webtoon of the same name and is set within a single high school classroom where a monthly voting system decides students’ social hierarchy. Kim Ji-yeon (Bona) plays Sung Su-ji, a transfer student who quickly learns that the class operates under a structured popularity ranking. Each student is assigned a score based on peer votes, and those at the bottom become designated targets, effectively legitimising school bullies through group consensus rather than individual aggression.

Jang Da-ah plays Baek Ha-rin, a key figure within the class’s social order whose influence shapes how the system is maintained, while Ryu Da-in appears as Myung Ja-eun, one of the students navigating the shifting alliances and pressures created by the rankings. As Su-ji becomes increasingly aware of how the system functions, she moves from observer to active resistance, challenging both the mechanics of the game and the classmates who enforce it.

The series is available on Paramount+ in selected regions, depending on licensing availability.

Revenge of Others stars Shin Ye-eun as Ok Chan-mi, a high school student whose life is upended after her twin brother dies under unclear circumstances. Refusing to accept the official explanation, she transfers to his school to investigate what really happened, gradually uncovering a network of violence, secrecy and manipulation beneath its surface.

Lomon plays Ji Soo-heon, a student with his own reasons for being drawn into Chan-mi’s search for answers. Their paths intersect as they navigate a school environment where reputations and influence often matter more than accountability, and where school bullies operate with varying degrees of protection depending on status and connections.

As Chan-mi pushes further into the investigation, she discovers that her brother’s death is tied not only to individual acts of aggression but also to a wider culture of intimidation and silence. The series builds its tension through shifting alliances, hidden motives and the constant uncertainty of who can be trusted, especially within a system where consequences are unevenly applied.

Blending revenge drama with mystery thriller elements, the story steadily reveals how school bullies can shape outcomes far beyond isolated incidents, affecting both victims and bystanders caught in the same hierarchy. It streams on Disney+ in selected regions.

Study Group stars Hwang Min-hyun as Yoon Ga-min, a student at a vocational high school who is far more committed to academics than his surroundings would suggest. Despite being known for his quiet determination and disciplined approach to studying, Ga-min finds himself enrolled in a school where disorder and physical intimidation regularly disrupt daily life.

His initial goal is simple: form a study group that can help him and his peers improve their academic performance and eventually secure better futures. However, that plan is repeatedly derailed as he is pulled into conflicts involving school bullies who dominate the school’s informal hierarchy. Rather than stepping away, Ga-min becomes increasingly involved in protecting classmates who are targeted, forcing him to balance his academic ambitions with constant physical confrontations.

The series uses an action-comedy structure to contrast Ga-min’s earnest, almost rigid focus on studying with the chaotic environment around him. Fight sequences are interwoven with moments of levity and classroom dynamics, highlighting how unstable the school setting has become and how frequently school bullies interrupt attempts at normal student life.

As the story progresses, the study group itself becomes a symbol of resistance and stability, representing students trying to carve out structure in an environment shaped by intimidation. The series is available on TVING and Viki in selected regions.

The King of Pigs stars Kim Dong-wook as Jung Jong-seok and Kim Sung-kyu as Hwang Kyung-min, two men whose lives are still shaped by a violent incident from their school years. The series is adapted from Yeon Sang-ho’s earlier animated film of the same name and expands its focus to examine how long-buried trauma resurfaces in adulthood.

The narrative moves between past and present, gradually revealing the school environment where bullying was normalised through rigid hierarchies and unchecked aggression. Jong-seok and Kyung-min’s shared history becomes the emotional core of the story, with each character carrying different interpretations of what happened and what it cost them. Rather than presenting school bullies as a distant memory, the drama frames them as a continuing presence that influences behaviour, relationships and mental state years after the events themselves.

As the investigation into the past unfolds, the series shifts into a psychological thriller, focusing less on direct confrontation and more on memory, guilt and suppressed anger. The tension builds through fragmented recollections and shifting perspectives, showing how the same incidents can be remembered in conflicting ways by victims and perpetrators.

The drama ultimately positions school violence as something that does not end at graduation, but continues to echo through adulthood in unpredictable and often destructive ways. It can be streamed through Prime Video in selected markets.

Angry Mom is far more confrontational as it is built around a parent stepping into the same environment as her child’s tormentors. Kim Hee-sun plays Jo Kang-ja, a former troublemaker who returns to her daughter’s high school after discovering she is being targeted by school bullies. What begins as concern quickly turns into direct intervention as she goes undercover to expose the abuse and the power structures protecting it. Kim Yoo-jung plays Oh Ah-ran, Kang-ja’s daughter, whose quiet suffering becomes the catalyst for the entire story. Ji Hyun-woo appears as Park No-ah, a teacher who becomes an uneasy ally as Kang-ja navigates the school’s internal politics.

Unlike many K-dramas about bullying where the issue is handled through student-led resistance alone, this drama positions an adult outsider as the central force challenging the system. The narrative moves between classroom dynamics, administrative cover-ups and escalating confrontations, gradually revealing how deeply embedded the bullying culture is within the school.

The series originally aired on MBC and is available on Viki in selected regions, depending on licensing availability.

Extracurricular stars Kim Dong-hee as Oh Ji-soo, a model student who appears quiet and disciplined at school while secretly running a criminal side business to fund his future. Park Ju-hyun plays Bae Gyu-ri, a classmate who becomes entangled in his operation after discovering his double life. Jung Da-bin appears as Seo Min-hee, while Nam Yoon-su plays Kwak Ki-tae, both representing different layers of privilege, pressure and vulnerability within the school’s social structure.

Although the series is not centred solely on bullying, it builds its tension around the broader ecosystem that allows exploitation and coercion to take hold among teenagers. School life is portrayed as highly stratified, with students navigating academic pressure, financial insecurity and shifting peer dynamics that often leave little room for safety or stability. Within this environment, students at different levels of the hierarchy exert influence over others, sometimes directly and sometimes through more subtle forms of pressure.

As the narrative progresses, the consequences of these choices escalate beyond the classroom, drawing in outsiders and exposing how easily control can shift when oversight is absent. Several characters find themselves caught between survival instincts and moral compromise, where decisions are driven less by ideology and more by immediate necessity.

The series uses this framework to show how school bullies and broader systems of intimidation can exist alongside ambition and normal school routines, blurring the line between victim and participant. It is available on Netflix.

Go Hye-jin, played by Shim Dal-gi, moves through school largely unnoticed, but not untouched. In Shadow Beauty, her daily life is shaped by quiet exclusion and appearance-based judgement, the kind of pressure that allows school bullies to operate without always resorting to overt confrontation. She is mocked in subtle ways, ignored in group settings and measured constantly against shifting beauty standards.

That sense of invisibility shifts completely when she logs on as “Genie”, a confident social media persona with thousands of followers. Online, she is admired and actively engaged with, a stark contrast to how she is treated in person. The gap between these two identities becomes harder to maintain as her online presence grows and expectations begin to spill into her offline life.

Choi Bo-min plays Lee Jin-sung, a classmate who becomes connected to her digital persona, while Lee Na-gyung appears as Yoo Na, a popular influencer whose polished image reflects the competitive culture of online visibility. Heo Jung-hee also features within Hye-jin’s school environment, reinforcing the everyday dynamics that define her experience at school.

Rather than focusing on direct clashes, the drama explores how school bullies can function through exclusion, comparison and reputation. It also shows how digital spaces can temporarily invert those hierarchies while introducing new forms of pressure that are just as difficult to escape.

It streams on Viki in selected regions.

Im Si-wan stars as Jang Byeong-tae in Boyhood, a coming-of-age drama set in rural South Korea during the 1980s. After being repeatedly targeted by school bullies at his previous school, he transfers in hopes of resetting his reputation and finally blending into a calmer environment. The move, however, proves more complicated than expected, as he quickly becomes entangled in the tightly knit social structure of his new school.

At the centre of his new life are misunderstandings that spread quickly through rumour and observation, shaping how classmates perceive him before he has a chance to define himself. In this setting, school bullies do not always act through direct violence at first; instead, status, alliances and reputation determine who becomes a target and why. Byeong-tae finds himself navigating these shifting dynamics while trying to avoid repeating the same patterns that followed him from his previous school.

Boyhood streams on Coupang Play.

Set during a school trip that spirals into chaos, Night Has Come places an entire class inside a real-life version of the Mafia game, where survival depends on identifying hidden killers among their peers. Lee Jae-in, Kim Woo-seok and Choi Ye-bin lead the ensemble as students who are suddenly forced to navigate suspicion, shifting alliances and rapidly collapsing trust.

The rules of the game are simple on paper but destabilising in practice. Each round ends with a vote, and the student with the most suspicion is eliminated. As fear builds, classmates begin revisiting old grievances and social hierarchies that once defined their school life. School bullies do not retain the same control they once had, but the tensions they created still shape how others respond under pressure.

Lee Jae-in plays Kim Jun-hee, who becomes increasingly involved in decoding the logic of the game while trying to keep the group from turning on itself. Kim Woo-seok appears as Go Kyung-jun, and Choi Ye-bin as Oh Yoo-jin, both navigating fractured relationships as paranoia spreads through the class.

What follows is less about the game itself and more about how quickly group dynamics deteriorate when trust becomes a liability. Former victims are no longer passive, and those who once held influence find their positions shifting as the stakes rise and certainty disappears.

Night Has Come streams on Viki in selected regions.

Kim Hyang-gi, Cha Eun-woo and Park Solomon star in Revenge Note (also known as Sweet Revenge 1), a teen fantasy drama built around a mysterious mobile app that allows users to take revenge on anyone whose name is entered into it. What initially seems like an online rumour quickly turns into a real tool that exposes hidden tensions within the school, particularly cases involving school bullies who have long operated without consequence.

At the centre of the story is Ho Goo-hee, played by Kim Hyang-gi, an ordinary student who unexpectedly becomes connected to the app and begins using it to address injustices around her. As she becomes increasingly involved, she is drawn into situations that force her to question the limits of punishment and what accountability should look like when school systems fail to intervene.

Cha Eun-woo plays a supporting brother figure in his acting debut role, while Park Solomon appears as Ji-hoon, a student who becomes entangled in the consequences of the app’s use. Their roles help frame the contrast between social popularity and hidden vulnerability within the school hierarchy.

The series maintains a lighter, more stylised tone compared to darker revenge-driven dramas, but it still explores how school bullies operate through status and exclusion, and how students react when formal systems of discipline are ineffective or absent.

Revenge Note streams on Viki in selected regions.

Park Ji-hu, Yoon Chan-young, Cho Yi-hyun and Lomon lead All of Us Are Dead, a zombie survival drama set almost entirely within Hyosan High School after a viral outbreak traps students inside the building. What begins as a contained emergency quickly escalates into a full-scale crisis, cutting off communication with the outside world and leaving students to survive on their own.

Before the infection spreads, the series establishes the school’s internal dynamics, including a clear hierarchy shaped by popularity, fear and physical intimidation. One of the early threads follows a student pushed to the edge by sustained school bullying, setting the emotional and narrative tone for how violence already existed within the school long before the outbreak.

As the situation deteriorates, classrooms, hallways and stairwells become fragmented survival zones. Groups form and dissolve based on immediate threats rather than long-standing relationships. Former victims, bystanders and school bullies are forced into the same spaces, where previous power structures lose meaning in the face of constant danger.

Park Ji-hu plays Nam On-jo, a resourceful student trying to survive alongside her classmates, while Yoon Chan-young appears as Lee Cheong-san, whose decisions become central to the group’s survival. Cho Yi-hyun plays Choi Nam-ra, a class representative whose arc reflects the shift from order to isolation, and Lomon portrays Lee Su-hyeok, a former delinquent navigating changing loyalties and responsibilities.

The series uses its horror framework to highlight how quickly control collapses when institutions fail, showing that the school’s internal system of school bullies and social hierarchy is fragile once survival becomes the only priority. It streams on Netflix.

The most compelling dramas about school bullies rarely focus solely on physical confrontations. Some, such as Weak Hero: Class 1 and Study Group, feature students fighting back directly. Others, including The Glory and The King of Pigs, examine how trauma persists long after graduation. Recent titles like Teach You a Lesson and Pyramid Game also shift attention toward the systems that allow school bullies to thrive in the first place. These 14 series show the many ways Korean dramas continue to explore school violence, revenge, survival and resistance across a wide range of genres.
