When people talk about K-dramas, they usually think of swoon-worthy romance, charming male leads with perfect hair, and unrealistic storylines that could melt even the coldest heart. Behind all the glitz and soft lighting, there’s another side of Korean storytelling that hits much harder, and that is their revenge films.
Revenge K-dramas come in all flavours: action, thriller, melodrama, and even romance. Some of them are inspired by real-life stories, especially seeing that South Korea has a very real problem with school and workplace bullying. These dramas dig deep into the ugliness of human behaviour, the trauma it causes, and the satisfaction (and sometimes tragedy) that comes with payback.
From bullied students to betrayed lovers, each show has a scintillating storyline that’ll have you hooked. If you’re ready to watch vengeance unfold, here are seven revenge K-dramas that serve it hot, slow, and oh-so-satisfying.
1. The Glory
If revenge had a face, it would be The Glory’s Moon Dong-eun (Song Hye-kyo). Split into two parts, this Netflix drama opens with one of the most harrowing depictions of school violence ever shown on television. As a teenager, Dong-eun is tortured by her wealthy classmates while the adults who should protect her turn a blind eye.
Years later, she returns as a calm, meticulous, and armed adult with a plan so precise it could be mistaken for art. She gets a new job as a homeroom teacher for her main bully’s child. Unlike many revenge stories that rely on physical violence, The Glory focuses on psychological warfare. Dong-eun dismantles her abusers’ lives piece by piece, exposing their cruelty and hypocrisy. What makes it chilling is how quiet the revenge is. It’s like watching a storm build behind glass.
It’s also written by Kim Eun-sook, the mastermind behind Goblin and Descendants of the Sun, two romance dramas that made it to our list of the Romance K-Dramas You NEED To See.
2. Weak Hero Class
If The Glory left you furious at the system, Weak Hero Class will leave you rethinking every school friendship you’ve ever had.
Yeon Si-eun (Park Ji-hoon) is a quiet, top-of-his-class student who becomes the next target of the school bully. Instead of cowering, he fights back. Not with brute strength, but with brains, strategy, and sheer willpower. What starts as a story about standing up to bullies turns into a raw exploration of friendship, loyalty, and the scars people hide.
The bond between Si-eun and his friends is beautiful and heartbreaking, and as the season progresses, that friendship slowly starts to fracture.
The cinematography, moody tones, clever lighting, and a sharp soundtrack make it feel more like an indie film than a typical K-drama. If you thought high school was rough, Weak Hero Class is a full-blown battlefield.

3. The Penthouse: War in Life
There’s messy, and then there’s The Penthouse. This show is the very definition of makjang (over-the-top and dramatic). It’s so addictive that you’ll be screaming at your screen by episode three.
Set in a luxurious 100-storey tower called Hera Palace, the series follows three women from different backgrounds whose lives intertwine through deceit, betrayal, and, of course, revenge. When a young girl falls to her death inside the building, her death sets off a chain of chaos among the rich residents.
Every character here is morally grey. Some are monsters in designer suits, others victims turned villains. It’s outrageous, heartbreaking, and occasionally ridiculous, but that’s the fun of it. Beneath the chaos, The Penthouse is really about class privilege, the pressures of education, and how far a mother will go when her child is wronged.
4. The Worst of Evil
Now, if you’re more into crime and gangster-style revenge, The Worst of Evil is your fix. Starring Ji Chang-wook and Wi Ha-joon, this drama is set in 1990s Seoul and follows a rural cop who goes undercover to infiltrate a powerful drug gang known as the Gangnam Union.
Ji Chang-wook’s character, Park Jun-mo, infiltrates the gang hoping to bring down its leader, Jung Gi-cheol, who is a ruthless kingpin with a complicated past. The deeper Jun-mo goes, the blurrier the line between justice and corruption becomes.
The fight choreography in this K-drama is incredible. It’s gritty, fast, and realistic, and I had to skip some fight scenes because they were too gory for me. Aside from the action, The Worst of Evil explores male friendship, ambition, and what happens when loyalty becomes poison.

5. Eve
If revenge were an art form, Lee Ra-el (Seo Yea-ji) would be Picasso. Seo Yea-ji plays Lee Ra-el, a woman who loses everything as a child when her father is killed. She spends the next 13 years planning a revenge so elegant and detailed that you almost admire her for it.
Under a new identity, she reinvents herself as a graceful ballet instructor and slowly infiltrates the world of the people who ruined her life: a powerful businessman and his equally manipulative wife. What follows is a mix of seduction, heartbreak, and emotional warfare.
