From web novel to webtoon to drama: how Korea builds one story in three formats
In Korea, a web novel is rarely written as a finished thing. More often, it's the first draft of a story that will be told again, twice, in two other formats, and the industry around it is built with that second and third telling already in mind.
The starting point is 웹소설, the web novel, published in short episodes called 회차, sold individually rather than as a complete book, and paced deliberately like a television serial rather than like a print novel arriving all at once. It's read across a handful of major platforms, among them KakaoPage, Naver Series, Munpia and Joara, each competing for the same readers and the same pool of stories worth adapting further. A survey by Korea's Ministry of Culture, Sports and Tourism together with KPIPA, published April 16, 2025 and based on responses from 800 creators across ten platforms, names the two leading genres: romance fantasy and a distinctly Korean staple sometimes called "regression," in which the protagonist is sent back in time to relive events with the benefit of hindsight. The same survey found that 79 percent of readers pay for what they read, spending an average of 8,032 won per session, a habit of small, per-episode payment that lines up neatly with the format's episodic shape.
What happens next to a successful web novel is where the format really shows its hand. Korean press, including the Korea Times and the Korea Herald, has documented for years a well-worn relay: a web novel that finds an audience gets adapted into a webtoon, the vertically scrolling comic format Korea effectively pioneered, and a webtoon that finds its own audience gets adapted again into a live-action or animated drama. The industry around webtoons is substantial enough to warrant its own annual accounting: KOCCA, the Korea Creative Content Agency, published its 2024 Webtoon Industry White Paper on January 15, 2025, documenting a sector organized around exactly this kind of intellectual-property relay rather than around any single format standing alone.
What makes this worth pausing on is less the existence of adaptation, which happens everywhere books get made into films, and more the direction of the causality. In most publishing markets, a novel is judged as a novel first, and adaptation, if it comes, arrives years later as a separate, later decision made by an entirely different set of people. In this Korean web novel relay, the text format seems to be built, from very early on, as the cheapest and fastest way to test whether a story has an audience worth spending webtoon and drama budgets on. The episode structure, sold and read one installment at a time, generates exactly the kind of granular audience data, which chapters get read, reread, dropped, that a publisher deciding whether to greenlight a webtoon adaptation would want to see before committing real money.
None of the sources reviewed here try to quantify how many web novels actually make that full three-format journey, and it's worth assuming the number is a minority of what gets published, the same way most novels anywhere never get optioned for film. What this relay does change is the posture of the format at the bottom of it. A web novel in this system isn't necessarily written to be the final version of the story. It's written, in a very real commercial sense, to find out whether the story deserves a final version at all, in whichever format actually turns out to be the right one.
