High school is a backdrop often chosen in Korean dramas, offering both relatable and tense atmospheres. The blend of mystery and thriller genres within a school setting amplifies the suspense, making these dramas favorites among fans who enjoy intricate plots and psychological tension.
Many Korean mystery thriller dramas set in high schools explore dark secrets, the pressures faced by students, and unusual events that disrupt everyday routines. The series on this list feature unique storylines, solid performances, and plot twists that keep audiences hooked with every episode.
1. Duty After School
Duty After School stands out with its fusion of school drama and sci-fi thriller. The story begins when high school students are suddenly drafted into military service after alien creatures invade Earth. Instead of preparing for university exams, students must train as soldiers to fight extraterrestrial threats. This drama captures the fear and anxiety faced by teenagers thrown into a life-or-death scenario. The government’s decision to conscript all students, including those in college, adds a unique layer of social commentary. According to various entertainment sources, the series is praised for its tense atmosphere and realistic depiction of unprepared youth forced into war.
2. Class of Lies
Class of Lies follows a sharp prosecutor who goes undercover as a temporary teacher to solve a murder case at an elite high school. As he interrogates the students, hidden secrets emerge, revealing the complex web of lies and deception among the staff and students. The drama excels in balancing legal investigation with the harsh realities of student life, including academic pressure and bullying. Data from Korean drama review platforms show that its success comes from its realistic portrayal of school politics and the darker side of elite education.

Save Me is commended for how it addresses sensitive themes like isolation, faith, and the power dynamics between authority figures and vulnerable youths.
4. Night Has Come
Night Has Come blends horror and thriller as a group of students on a school retreat are forced into a deadly ‘mafia’ game. Unlike the innocent party game, this version has fatal consequences—eliminated players lose their lives in real life, not just in the game.

Viewer data from drama streaming sites indicate that the unpredictable plot twists and psychological mind games make it a top pick among fans of suspenseful school stories.
5. Study Group
Study Group centers on Yoon Ga Min, a student who wants to excel academically but is better known for his fighting skills.

The drama provides a raw look at youth violence, peer pressure, and the determination to rise above one’s environment. Its mix of action sequences and heartfelt moments gives a balanced view of what students face in some of Korea’s toughest schools. Reviews highlight the show’s honest approach to bullying and camaraderie.
6. Extracurricular
Extracurricular draws viewers into the secret world of high school students leading double lives. It tells the story of students who get involved in illegal businesses to survive and finance their ambitions. As their activities attract the attention of criminals and law enforcement, the stakes rise quickly, making for a tense and gritty narrative. The drama stands out for its unfiltered exploration of youth crime and its consequences. Audience feedback often mentions how the show elevates stories of marginalized teens who are willing to break rules for the sake of their future.
7. Weak Hero Class
Weak Hero Class is based on a popular webtoon and dives deeply into the subject of school bullying.
