MovieUnit ratings are editorial scores, not official ratings.
1. Hierarchy
Hierarchy takes the familiar elite-school setting and puts social status at the center of the story.
Set at Jooshin High School, the drama follows a school where the most privileged students effectively control the social order. Everything changes when transfer student Kang Ha arrives and begins challenging the school’s established hierarchy. Netflix describes Jooshin as a school controlled by its top 0.01% of students.
What makes Hierarchy interesting?
The biggest attraction is its glamorous setting contrasted with the darker issues underneath it.
Money, family influence, popularity and relationships determine how students are treated. The arrival of an outsider creates tension and slowly exposes the secrets behind this seemingly perfect school.
The drama also mixes romance, mystery and revenge, making it more than a straightforward school romance.
What works
- Stylish production and visuals
- Interesting rich-school setting
- Romance and mystery elements
- Strong focus on privilege and social hierarchy
- Easy binge-watch at seven episodes
What doesn’t
The drama can feel more interested in its glamorous world than in fully developing every character. Some viewers may also find parts of its storyline familiar if they’ve already watched several elite-school K-dramas.
Who should watch it?
Watch Hierarchy if you enjoy:
- Rich-school dramas
- Romance
- Secretive characters
- School power struggles
- Revenge stories
MovieUnit Rating: 7/10
2. Extracurricular
If you want a high school K-drama that feels significantly darker, Extracurricular is one of the strongest choices on this list.
The 2020 Netflix series follows model student Oh Jisoo, who secretly becomes involved in a serious criminal operation. His carefully controlled double life begins falling apart when another student discovers his secret. Netflix lists the show as a teen crime thriller and high-school drama with 10 episodes.
Why Extracurricular stands out
The clever part of the story is that Jisoo isn’t presented as a typical heroic teenager.
He’s academically successful and seemingly quiet at school, but outside the classroom he’s involved in something extremely dangerous. That contrast creates much of the show’s tension.
Netflix’s original announcement described the series as following students who make choices involving crime and then face consequences that can’t easily be undone.
What works
- Dark and unpredictable storyline
- Strong tension
- Interesting morally complicated characters
- Crime element makes it different from typical school dramas
- Good pacing
What doesn’t
This isn’t a feel-good high school drama. Some decisions made by the characters can be frustrating, and the story becomes increasingly intense as their secrets collide.
Who should watch it?
Extracurricular is a good choice if you prefer:
- Crime thrillers
- Dark K-dramas
- Psychological tension
- Unpredictable stories
- Anti-hero-style characters
MovieUnit Rating: 8.5/10
3. Teach You a Lesson
Released in 2026, Teach You a Lesson puts a completely different spin on the school-drama formula.
The series follows the fictional Teachers’ Rights Protection Bureau, whose inspectors step into schools when conflicts between students, teachers and parents become extreme. Netflix describes the series as an action-packed Korean drama dealing with social issues and school conflicts.
Why watch Teach You a Lesson?
The biggest difference is the presence of adult investigators who enter the school environment.
Instead of following only students dealing with bullying, the drama explores how institutions, parents, teachers and students can contribute to problems inside schools.
And unlike many serious school dramas, it isn’t afraid to use fights, action sequences and dark comedy.
Netflix’s official announcement specifically describes the series as featuring hand-to-hand fights, car chases and unconventional methods of dealing with school problems.
What works
- Fresh approach to the school-drama genre
- Action-heavy storytelling
- Social issues
- Strong adult characters
- Good choice for viewers who want less romance
What doesn’t
If you’re looking for a traditional teenage romance or coming-of-age story, this probably isn’t the right choice.
Who should watch it?
Try it if you enjoy:
- Action K-dramas
- School-related stories
- Social issue dramas
- Revenge and justice themes
- Webtoon adaptations
MovieUnit Rating: 8.3/10
4. Revenge of Others
Revenge of Others combines a school setting with a murder mystery.
After Park Wonseok dies at school, his twin sister Ok Chanmi refuses to believe that his death was suicide. She transfers to his school to discover what really happened.
At the same time, a mysterious figure begins taking revenge on students who bully others. Chanmi starts wondering whether this so-called “hero” has a connection to her brother’s death. Disney+ describes the series around exactly this mystery and revenge premise.
Why it’s worth watching
The mystery gives the drama a strong hook from the beginning.
Instead of simply asking who is bullying whom, the story keeps introducing new questions about Wonseok’s death, the mysterious vigilante and the secrets surrounding the students.
That makes Revenge of Others particularly appealing to viewers who want a school drama with a proper thriller component.
What works
- Strong mystery setup
- Revenge storyline
- School bullying theme
- Good suspense
- Several character secrets
- 12-episode format
What doesn’t
The number of twists and character relationships can occasionally make the story feel complicated.
It’s also much darker than a conventional teenage drama.
Who should watch it?
Choose this one if you like:
- Murder mysteries
- Revenge stories
- School thrillers
- Dark K-dramas
- Suspenseful investigations
MovieUnit Rating: 8.2/10
5. The Glory
Few dramas on this list explore the long-term consequences of school bullying as directly as The Glory.
The story follows Moon Dong-eun, who suffers severe abuse during high school. Years later, she begins executing a carefully planned revenge against the people responsible. Netflix describes the series as the story of a woman who survives horrific high-school abuse and later puts an elaborate revenge plan into motion.
Why The Glory is different
The drama doesn’t simply show revenge as a quick response.
Instead, it spends time showing how the protagonist’s traumatic school experience affects her life years later.
The story then moves beyond the school environment, showing how the people involved have built adult lives while Dong-eun has spent years preparing for her confrontation with them.
What works
- Strong central character
- Long-term revenge storyline
- Excellent suspense
- Dark atmosphere
- Strong supporting performances
- Serious treatment of bullying and its consequences
What doesn’t
It’s emotionally heavy and contains disturbing scenes involving abuse and violence. It’s definitely not a light school drama.
Who should watch it?
Watch The Glory if you’re looking for:
- Revenge K-dramas
- Dark dramas
- Bullying-related stories
- Psychological tension
- Long-form character development
MovieUnit Rating: 9/10
6. Weak Hero
If you’re looking specifically for school bullying + action, Weak Hero deserves a place near the top of your watchlist.
The story centers on Yeon Si-eun, an academically gifted but physically unimposing student who becomes a target of violence. Rather than relying purely on physical strength, Si-eun uses intelligence, observation and whatever tools are available to confront his opponents.
Netflix currently lists Weak Hero with two seasons and describes it as an action-driven high-school story involving bullying, friendship and violent conflicts.
What makes Weak Hero special?
The protagonist isn’t the typical physically powerful action hero.
His greatest weapon is his intelligence.
That changes the way fight scenes work. Instead of simply watching the strongest character win, viewers see Si-eun analyze situations and find ways to survive opponents who appear physically stronger.
The friendship between Si-eun, Ahn Su-ho and Oh Beom-seok also gives the story an emotional foundation. The original Weak Hero Class 1 was an eight-episode series released in 2022.
What works
- Excellent action sequences
- Strong friendships
- Intelligent protagonist
- Emotional character development
- Bullying storyline
- High tension
What doesn’t
The violence becomes intense, and the story can be emotionally difficult. It’s also not the kind of school drama where conflicts are solved easily.
Who should watch it?
Definitely consider it if you enjoy:
- School action dramas
- Bullying stories
- Underdog characters
- Friendship dramas
- Korean action thrillers
MovieUnit Rating: 9/10

For a serious, long-form revenge story, The Glory is the obvious genre match.
And if you want school bullying, friendship and intense action, Weak Hero is a strong fit.
MovieUnit’s overall recommendation: Don’t choose only based on the “high school” label. These dramas use the setting to tell very different stories, so your preferred genre should determine where you start.
