The last 20 years have given us some of the best K-dramas to date. In the '90s, K-dramas were known for their melodramatic plots centered on love and family, and by the 2000s, they had paved the way for lighter, slice-of-life romantic comedies. Over the past two decades, however, K-dramas have taken bolder, more experimental directions. They're no longer just dramas; the term now covers a whole spectrum of genres, from thrillers to satires.

But at the end of the day, what makes a K-drama truly great is its ability to connect with audiences. No matter how experimental these shows get, the best ones leave a lasting impression and give people something to talk about for years to come. From a revenge story set in one of Seoul's most popular districts to a Netflix global phenomenon, here are the best K-dramas of the last 20 years, ranked.

7 'Princess Hours' (2006)

Imagine finding out you're going to marry a prince when you're just an ordinary high school student. That's exactly what happens to Shin Chae-kyeong (Yoon Eun-hye) in Princess Hours, when an old royal agreement ties her to Crown Prince Lee Shin (Ju Ji-hoon). Surprisingly, Chae-kyeong never wanted this Cinderella story. The two barely get along, either. Chae-kyeong is bubbly and down-to-earth, while Shin is cold and arrogant, making their arranged marriage anything but a fairy tale.

Princess Hours was one of the early K-dramas to reach international audiences, riding the first wave of Hallyu's growing popularity. Shows about royalty might not appeal to everyone, but there's something fun about a contemporary high school romance set in a fictional South Korean monarchy rather than the usual world of British royals. With its whimsical take on the enemies-to-lovers trope, Princess Hours turns royal protocol and an unwanted arranged marriage into a charming romance that shows how love can blossom in the most unexpected circumstances.

6 'Doctor Slump' (2024)

Doctor Slump follows Yeo Jeong-woo (Park Hyung-sik) and Nam Ha-neul (Park Shin-hye), two gifted students who become school rivals. Jeong-woo grows into a successful plastic surgeon, while Ha-neul becomes a talented anesthesiologist. However, their perfect lives fall apart when a scandal destroys Jeong-woo's career, and Ha-neul reaches her breaking point after years of pushing herself too hard. Their unexpected reunion gives both of them a chance to start over, even if burying their old grudges takes some time.

The midlife crisis is out; the quarter-life crisis is in. With Jeong-woo and Ha-neul struggling to figure out what comes next, Doctor Slump feels like a shoulder to cry on during a rough patch. Rather than rushing to solve every problem, the series focuses on finding people who understand what you're going through. Between awkward encounters, heartfelt conversations, and a romance that develops naturally, the show reminds viewers that getting back on your feet doesn't always mean having everything figured out. Sometimes, all you need is someone who makes the hard days a little easier to face.

5 'Itaewon Class' (2020)

After losing his father and going to prison following a clash with the son of a powerful businessman, Park Sae-ro-yi (Park Seo-joon) has every reason to give up. Instead, he sets his sights on taking down the Jangga Group, the company responsible for turning his life upside down. His plan starts with DanBam, a small bar in Seoul's Itaewon district, where he brings together an unlikely team of people who don't quite fit in anywhere else.

There are tons of K-dramas that feature revenge plots, but what makes Itaewon Class particularly exciting is Sae-ro-yi's crew, which is one of the most diverse casts in K-drama in terms of representation. This is fitting, considering Itaewon itself is a hub of multiculturalism in Seoul. From a transgender chef to a Guinean-Korean employee, DanBam becomes a place where people who are often pushed aside can find their footing. Watching this ragtag team grow into a real threat to one of Korea's biggest food empires is incredibly satisfying.

4 'SKY Castle' (2018–2019)

SKY Castle takes a darkly funny look at South Korea's obsession with academic success, showing just how far some parents will go to give their children a competitive edge. Set in an exclusive neighborhood filled with wealthy families, the drama follows parents who treat getting into the country’s top universities, collectively known as SKY, as the ultimate measure of success. Behind their picture-perfect homes and polished appearances, however, lies a cutthroat world of fierce competition, family pressure, and desperate attempts to stay ahead.

In South Korea, the annual Suneung college entrance exam can shape a student's future, making the pressure to succeed incredibly intense. SKY Castle turns that pressure into a ruthless satire, exposing how the pursuit of prestigious degrees can come at the expense of children's happiness and mental well-being. Although the schemes in the series are outrageous and fictional, the parents' obsession is eerily scary. It's the perfect balance of frightening and amusing, addressing something considered the status quo in society until someone ends up getting hurt in the process, all to protect their social standing.

Collider Exclusive · Universe Personality Quiz Which Iconic Universe Do You Belong in the Most? Star Wars · Lord of the Rings · Harry Potter · Game of Thrones · Star Trek

FIND YOUR UNIVERSE →

01

What gives your life its deepest sense of meaning? Every universe is built around a different answer to this question.

ABeing part of something larger than myself — a cause, a rebellion, a fight for freedom that outlasts me. BThe journey itself — the places I'll go, the companions beside me, the world I'll discover on the way. CLearning — unlocking what I'm capable of, understanding the world's hidden mechanics, growing into something more. DLegacy — the name I leave behind, the power I build, the mark I make before the world moves on without me. EUnderstanding — exploring what exists beyond the horizon and asking what it means to be alive in a universe this vast.

NEXT QUESTION →

02

Which kind of world do you most want to inhabit? The environment shapes who you become. Choose carefully.

AA galaxy of planets, each with its own culture — connected by conflict, trade, and the Force. BAncient lands of breathtaking beauty, deep history, and a creeping darkness at the edges. CA world hidden inside our own — full of wonder, community, and magic waiting to be learned. DA brutal, beautiful continent where power is everything and every alliance is a calculation. EA future where humanity has reached the stars — and must decide what kind of species it wants to be.

NEXT QUESTION →

03

How do you prefer your conflicts resolved? The shape of a world's conflicts tells you everything about its soul.

AThrough sacrifice and courage — someone has to make the impossible choice so others don't have to. BThrough fellowship — the impossible becomes possible when the right people walk the same road. CThrough growth — confronting what you fear, understanding what you lack, and becoming equal to the challenge. DThrough strategy — outthinking, outmaneuvering, positioning yourself so the outcome was never in doubt. EThrough dialogue — finding the third option, the peaceful resolution, the answer that doesn't require a body count.

NEXT QUESTION →

04

Who do you want beside you when things get difficult? Your ideal companions reveal the world you were made for.

AA small crew — a pilot, a rogue, a warrior — each broken in their own way, unbeatable together. BA fellowship of different kinds of people, bound by purpose and deepened by the long road. CFriends who grew up alongside me — who knew me before I knew myself, and stayed anyway. DAllies whose loyalty I've earned — and tested — and whose ambitions align with mine, for now. EA crew of brilliant, curious, principled people from every corner of known space.

NEXT QUESTION →

05

What is your relationship with power? How you seek, wield, or resist power is the map of who you are.

AI want to use it to protect — and I'm terrified of what I might become if I'm not careful. BI distrust it. The most important power in this story is the courage to give it up. CI want to earn it — through knowledge, through effort, through becoming someone worthy of it. DI want to wield it. Preferably before someone else decides to wield it against me. EI want to understand it — its structures, its limits, its ethical dimensions. Power without accountability is the real threat.

NEXT QUESTION →

06

How does your universe treat good and evil? A world's moral architecture tells you more about it than any map.

AThere is a dark side and a light side — and the choice between them is always present, always personal. BEvil is real and ancient and patient — and goodness, however small, is the only thing that can undo it. CGood and evil are real, but they live inside people — and people are complicated, always capable of both. DGood and evil are mostly a matter of perspective and proximity. Power is the only honest currency. EEvil is usually the result of ignorance, fear, or broken systems — and understanding it is the first step to solving it.

NEXT QUESTION →

07

What role would you naturally fall into? Every universe has archetypes. Which one fits you without trying?

AThe reluctant hero — ordinary origins, extraordinary moment, changed forever by the choice to act. BThe unlikely carrier — the one nobody expected to matter most, quietly bearing the weight of everything. CThe student — not yet who I'll become, learning through every mistake, growing into something the world needs. DThe player — sharp enough to see the game for what it is, ambitious enough to try to win it. EThe explorer — drawn to the unknown, driven by curiosity, most alive when standing somewhere no one has stood before.

NEXT QUESTION →

08

What do you ultimately believe about the future? The answer to this is the clearest window into which universe already lives inside you.

AThat hope is real — that even in the darkest galaxy, a new hope is always possible. CThat even the smallest person can change the course of the future, if they have the courage to try. CThat love and friendship and doing what's right will matter in the end, even when everything says otherwise. DThat the wheel keeps turning — that power shifts, winters end, and what endures is those willing to fight for it. EThat humanity — or whatever we become — is capable of extraordinary things, if we choose to be.

Your Universe Has Been Chosen You Belong In…

Your answers point to the iconic universe your values, your instincts, and your particular way of seeing the world were built for. This is where you would find your people — and your purpose.

Star Wars

You believe in the cause — in the idea that freedom is worth fighting for even when the odds are impossible and the empire is vast.

• You are drawn to the moral clarity of a universe where hope itself is a form of resistance.
• You'd find your people in the Rebellion — a ragtag coalition of true believers held together by conviction more than resources.
• Star Wars is fundamentally a story about ordinary people choosing to matter in an extraordinary conflict — and that is exactly your kind of story.
• The Force may or may not be with you. But the will to use it for something larger than yourself certainly is.

Lord of the Rings

You understand, in the deepest part of yourself, that the journey matters as much as the destination — and that the world's beauty is worth protecting even at great cost.

• Middle-earth is a world of ancient wonder, deep friendship, and a darkness that only retreats when enough small acts of courage accumulate.
• You would thrive here because you value the fellowship more than the glory — the road more than the arrival.
• Tolkien's universe rewards patience, loyalty, and the willingness to carry something heavy across a very long distance.
• Those are not burdens to you. They are simply how you move through the world.

Harry Potter

You believe that love, loyalty, and doing what's right are not naive sentiments — they are the most powerful forces in any world, magical or otherwise.

• The Wizarding World is a place of wonder hidden in plain sight, where learning is transformative and the bonds you form at school follow you into every battle.
• You would flourish here because you take both the magic and the friendships seriously — and you understand that one without the other is incomplete.
• Harry Potter's universe ultimately rewards those who choose to stand for something even when standing is terrifying.
• That choice — made quietly, without guarantee — is something you understand completely.

Game of Thrones

You see the world clearly — its power structures, its hypocrisies, its brutal arithmetic — and you are not paralysed by that clarity. You use it.

• Westeros is a world that rewards intelligence, adaptability, and the willingness to understand that every alliance is also a negotiation.
• You would survive here — possibly thrive here — because you don't confuse the world as it is with the world as you'd like it to be.
• Game of Thrones is a story about what happens when the idealists and the realists collide. You are sharp enough to know which one lasts longer.
• Winter always comes. You are already prepared.

Star Trek

You believe the future is worth building — that curiosity, cooperation, and the expansion of understanding are not just ideals but the most practical path forward for any civilisation.

• Star Trek is a universe where the questions matter as much as the answers, and where encountering something utterly alien is cause for wonder rather than fear.
• You would belong here because you are fundamentally optimistic about what intelligence and decency can achieve — while being honest about how hard that achievement is.
• The Federation is the universe's most ambitious thought experiment: what if we actually got better?
• You don't just hope that's possible. You think it's the only thing worth working toward.

3 'Squid Game' (2021–2025)

With mounting debts and nowhere else to turn, Seong Gi-hun (Lee Jung-jae) agrees to join a mysterious competition promising a massive cash prize. Alongside 455 other contestants, he plays familiar childhood games, from Red Light, Green Light to the dalgona challenge. However, losing any game comes with a deadly price — contestants who fail to complete a challenge are killed on the spot. As the prize money grows with every death, the players must decide how far they're willing to go.

It would be remiss to talk about K-drama masterpieces without mentioning the chokehold Squid Game had on global audiences. What initially became a hit pandemic watch evolved into a cultural phenomenon, offering a unique take on capitalism and the working class through a setting that's both ridiculously childish and brutally cruel. The scariest part is how believable that desperation for money is, especially when each of these players have valid reasons to win that cash prize.

2 'Mr. Sunshine' (2018)

Set in the final years of the Joseon era, Mr. Sunshine follows Eugene Choi (Lee Byung-hun), a boy born into slavery who escapes to the United States. Years later, he returns to Korea as a U.S. Marine Corps officer and meets Go Ae-shin (Kim Tae-ri), a noblewoman secretly fighting for her country's independence. Despite coming from completely different worlds, the two fall in love as Korea faces growing threats from foreign powers and Japanese occupation.

Western audiences might recognize Byung-hun from thriller-heavy projects like Squid Game or the G.I. Joe movies, but Mr. Sunshine shows just how good he is in a more dramatic role. Paired with the equally decorated Tae-ri, the two deliver a tour de force performance as a couple whose love is constantly tested by the world around them. Mr. Sunshine drives home the heartbreaking truth that love doesn't always get a happy ending, especially when history gets in the way. Sometimes, loving someone means accepting that you might not get the future you always dreamed of.

1 'When Life Gives You Tangerines' (2025)

Set on Jeju Island in the 1950s, When Life Gives You Tangerines follows Ae-sun (IU) and Gwan-sik (Park Bo-gum), two childhood sweethearts who couldn't be more different. Ae-sun is outspoken, full of dreams, and passionate about poetry, while Gwan-sik is quiet, practical, and more comfortable showing his feelings through actions than words. Despite their differences, the two grow closer as they navigate the challenges of growing up and figuring out what they want from life.

Spanning seven decades, their love story unfolds during some of Korea's most difficult periods, when war, poverty, and family responsibilities often get in the way of personal happiness. As Ae-sun and Gwan-sik grow older, they learn that life doesn't always go according to plan, and love alone can't fix everything. Still, When Life Gives You Tangerines balances its heartbreaking moments with plenty of humor, warmth, and little victories. It's a reminder that even when life gets messy, there are still good things worth holding onto.
