K-dramas based on webtoons have been a steady hit pipeline since at least 2014, when tvN’s office drama Misaeng turned a phone comic into a national talking point. Studios adapt webtoons because the audience already exists: a series that millions read every week comes with proven characters, a ready-made storyboard and comment sections that show exactly which scenes people care about.
If you loved Itaewon Class, Sweet Home, All of Us Are Dead or Moving, you already watched one. Below: how webtoons work, why the industry keeps buying them, the adaptations to know, and how to read the originals legally from outside Korea.
Key takeaways
- A webtoon is a Korean digital comic made for vertical scrolling on a phone, released in weekly episodes, usually in full color.
- Netflix originals Sweet Home, Hellbound, All of Us Are Dead and Mask Girl all started as webtoons, so you can stream them in any Netflix region.
- Several webtoon creators wrote or directed the screen versions themselves: Jo Kwang-jin (Itaewon Class), Kang Full (Moving) and Yeon Sang-ho (Hellbound).
- The legal English versions live on apps such as WEBTOON, Tapas and Tappytoon, and which app holds a title changes by series and country.
Why are so many K-dramas based on webtoons?
The short answer is risk. A drama costs a lot to produce, and a webtoon arrives pre-tested. Before a producer ever pitches it, the story has run for months or years in public, with view counts, likes and thousands of reader comments per episode. That is market research no writers’ room can buy.
The second reason is ownership. Korea’s two biggest webtoon platforms belong to its two biggest internet companies, Naver and Kakao, and both built their own production arms (Naver’s Studio N and Kakao Entertainment’s drama labels) to turn their comics into shows. The platform that publishes the comic now often develops the drama too, so adaptation is a business plan, not a lucky licensing deal.
The third reason is you. Webtoons reached readers abroad through English apps years before many of their dramas existed, so a series like Sweet Home had a global fanbase waiting when Netflix released it. For a streamer chasing worldwide subscribers, that built-in international audience matters as much as Korean ratings.
How webtoons work: the vertical-scroll comic explained
A webtoon (the name blends “web” and “cartoon”) is a comic designed for a phone screen. Instead of pages with panel grids, you scroll down one long vertical strip. Panels are spaced out so the gap itself does work: a long white stretch before a reveal acts like a pause in a film edit.
Weekly episodes and reader comments
Most series update on a fixed weekday, one episode at a time, much like a TV schedule. Readers rate and comment on every episode, and top comments sit right under the final panel. Creators and editors watch that feedback closely, which is part of why webtoon pacing tends to end each chapter on a hook.
How webtoons make money
Platforms usually let you read many episodes free and charge for speed. Kakao popularized “wait until it’s free”, where a new episode unlocks after a waiting period unless you pay to read now. The English WEBTOON app sells coins for early-access episodes (Fast Pass) and unlocks older ones gradually through Daily Pass. The exact rules and coin costs are set inside each app, so check there.
Why the format suits television
Vertical scrolling reads a lot like a camera moving down a shot list. Directors often describe webtoons as storyboards that come pre-drawn, with framing, close-ups and cliffhangers already decided. A 16-episode drama arc (the classic Korean miniseries shape) maps neatly onto a webtoon’s chapter-by-chapter build.
Why studios keep buying webtoon rights
Studios give a few practical reasons for adapting webtoons, and they explain most of the deals you see announced.
- Data before casting. Comment threads show which characters readers love, which twists landed and which side couples have their own fandom. That shapes casting and screen time.
- Genre range. Webtoons cover zombies, monsters, office life, revenge and fantasy romance. Network TV in Korea used to lean on family melodrama; webtoons gave streamers a stockpile of genre stories.
- A finished ending. Many webtoons are complete before filming starts, so writers know where the story lands. Korean dramas that air while being written can lose their way late in a run; an adaptation has a map.
- One story, many products. A single title can become a drama, a film, an animated series, merchandise and a translated comic. Industry people call this IP (intellectual property), and webtoons are among the easiest IP to extend.
The business side shows up in the news. WEBTOON Entertainment, the Nasdaq-listed company behind the English WEBTOON app, reported its third-quarter 2026 results this month, and according to FinancialContent, its sales came in below analyst estimates. Full commentary is in the earnings call highlights reported by Yahoo Finance. The company counts adaptations as part of the value of its catalog, which tells you how central screen deals are to the webtoon industry. This is not investment advice.
10 well-known K-dramas based on webtoons and where to stream them
Start here if you want a clear sense of how wide the genre spread runs. Streaming rights shift by country, so treat the right-hand column as a starting point and confirm on the service itself.
| Drama | Original webtoon and creator | Genre | Where to look first |
|---|---|---|---|
| Misaeng (tvN) | Misaeng by Yoon Tae-ho | Office drama | Varies by region; check Viki and local services |
| Cheese in the Trap (tvN) | Cheese in the Trap by Soonkki | Campus romance, thriller edge | Varies by region |
| Itaewon Class (JTBC) | Itaewon Class by Jo Kwang-jin | Revenge, business | Netflix in many regions |
| Sweet Home | Sweet Home by Kim Carnby and Hwang Young-chan | Monster horror | Netflix original |
| Hellbound | Hellbound by Yeon Sang-ho and Choi Kyu-seok | Supernatural thriller | Netflix original |
| All of Us Are Dead | Now at Our School by Joo Dong-geun | Zombie, high school | Netflix original |
| True Beauty (tvN) | True Beauty by Yaongyi | Teen romantic comedy | Varies by region |
| Yumi’s Cells | Yumi’s Cells by Lee Dong-gun | Romance with animated brain cells | TVING in Korea; varies abroad |
| Business Proposal (SBS) | Webtoon of HaeHwa’s web novel | Office romantic comedy | Netflix in many regions |
| Moving | Moving by Kang Full | Superhero family drama | Disney+ original |
The same pipeline runs into cinema. The Along with the Gods films came from Joo Ho-min’s afterlife webtoon, and Netflix’s Mask Girl adapted the dark webtoon by Maemi and Huimang.
Which webtoon adaptation should you watch first?
Pick by mood. Want something grounded and adult? Misaeng is still the benchmark for office drama. For horror, Sweet Home and All of Us Are Dead are the easiest to find abroad. If you want comfort viewing, Business Proposal and True Beauty are light, quick and built around romantic misunderstandings.
From web novel to webtoon to K-drama: how the pipeline works
Plenty of hit webtoons are adaptations themselves. A story often starts as a web novel (serialized prose fiction read on platforms such as Kakao Page), becomes a webtoon once it gathers readers, and then gets a drama or animation deal. Business Proposal followed that path, and so did many fantasy romances, including The Remarried Empress, whose webtoon you can read legally in English.
Each step filters the story. The prose version tests the plot cheaply, the webtoon tests the characters visually, and by the time a studio films it, the story has survived two rounds of reader judgment. That is why the same handful of platforms show up in drama credits again and again.
A worked example: Itaewon Class
Jo Kwang-jin’s webtoon followed Park Sae-ro-yi, an ex-convict who opens a small bar in Seoul’s Itaewon district to take on the food conglomerate that ruined his family. JTBC’s drama kept that spine and brought Jo in to write the screenplay himself, which kept the tone close to the comic. Its global reach came largely through Netflix, which made a Seoul nightlife neighborhood familiar to viewers who had never been to Korea.
What changes between the webtoon and the drama
Expect changes, and expect fans to argue about them. A few patterns repeat across adaptations.
- Compression. A webtoon that ran for years has to fit a season. Side plots get merged or cut, and minor characters vanish.
- Different endings. If the webtoon was still running during production, the drama may invent its own finish. Even complete stories sometimes get a softer or more open ending on TV.
- Tone shifts for broadcast. Gore and violence that work in a comic may be toned down on network TV, while streamer originals can stay closer to the source.
- Casting debates. Readers have a fixed image of each character’s face, so casting news is often the loudest moment of an adaptation’s life.
How to read the original webtoon legally from abroad
Reading the official version pays the creators whose work became the drama, and the translations are generally better than fan scans. Here is the order to check.
- WEBTOON (Naver’s global app). The biggest English catalog of Naver-published series, with free episodes and paid early access.
- Tapas. Owned by Kakao Entertainment, and home to many Kakao-published comics and novels in English.
- Tappytoon, Manta and Lezhin. Paid platforms that license specific Korean titles, including many romance and drama-source series.
- The creator’s and publisher’s announcements. When a drama is announced, platforms often promote the original, and official social accounts say where it is licensed.
Availability is title by title and country by country. A series on WEBTOON in the US might not be there in another market, and some adapted webtoons have no official English edition at all. Search the title inside each app rather than trusting a third-party list, and skip pirate sites, which carry malware risk and pay nothing to artists.
What reading a webtoon actually costs
Effort-wise, very little: one episode takes a few minutes, and the free tier on most apps lets you catch up slowly. Money-wise, it depends on how impatient you are. Coin prices and unlock rules are listed in each app’s store, so check them there before buying a bundle.
Should you read the webtoon or watch the K-drama first?
Watch first if the drama is already complete and you mostly care about the story on screen. The show is a finished experience, and the webtoon then adds back the subplots that got cut.
Read first if the webtoon is finished and the drama is only announced. You will know the full arc, and you can judge the adaptation on its own choices. Fantasy and romance readers often prefer this route because the comic usually has more inner monologue than any script can carry.
For long-running action series, do both in parallel: watch a season, then read up to where it ended. That keeps you spoiler-safe and lets you compare scenes while they are fresh. A bowl of homemade tteokbokki, the snack that turns up in half the school webtoons ever drawn, is optional.
FAQ
What is a webtoon?
A webtoon is a Korean digital comic made to be read by scrolling down a phone screen. Episodes are released on a schedule, often weekly, and most are in full color. Naver and Kakao run the largest platforms in Korea.
What was the first big K-drama based on a webtoon?
Webtoons fed screen projects before 2014, but tvN’s Misaeng that year is the adaptation most often credited with proving the model. Its realistic look at office life drew attention well beyond comic readers. After it, broadcasters and streamers treated webtoons as a regular source.
Are Netflix K-dramas based on webtoons?
Many are. Netflix originals Sweet Home, Hellbound, All of Us Are Dead and Mask Girl all adapt webtoons. Netflix also streams licensed broadcast dramas from webtoons, such as Itaewon Class and Business Proposal, in many regions.
Where can I read the webtoon of a K-drama in English?
Check the WEBTOON app first, then Tapas, Tappytoon, Manta and Lezhin. Licensing varies by title and country, so search each app directly. Some adapted webtoons have no official English release yet.
Is the webtoon better than the drama?
It depends on what you want. Webtoons usually have more subplots and inner thoughts, while dramas add actors, music and tighter pacing. Many fans enjoy both and treat them as two versions of one story.
Why do K-drama endings differ from the webtoon?
Some dramas are filmed while the webtoon is still running, so writers need their own ending. Others change the finale to fit a season length, broadcast rules or a wider audience. When the creator writes the script, as with Itaewon Class and Moving, the screen version tends to stay closer.
What to watch and read next
Keep an eye on new seasons of established adaptations. Yumi’s Cells is still drawing coverage, including a recent look at its second season from K-Culture with Jae-Ha Kim, and it pairs well with the original comic by Lee Dong-gun.
For a quick plan: pick one drama from the table that matches your mood, finish it, then open the WEBTOON or Tapas app and search the original title. Follow the creator’s official accounts and the platform’s news page, because that is where adaptation deals usually get announced first.
