K-Drama Script Writing for International Writers: How Korean Drama Development Works and Where a Foreign Writer Fits

The writer-led system

The single biggest difference from American television: in Korea the drama writer (jakga) is the author of the show in a way a US staff writer is not. A drama is usually written by one lead writer, often with one or more assistant writers, across its whole run, rather than by a writers' room. The writer's name is a selling point; established writers have followings and their next project is news. Directors (PDs) and production companies are partners, but the script is the writer's.

Practical consequences:

• There is no room to join. The route to writing a drama is to become the writer of one, not to be staffed on one. Assistant-writer positions exist and are the traditional apprenticeship, in Korean, in Korea.
• The pitch is the writer's package. Development begins with a planning document and sample episodes, not with a room breaking a season.
• The writer often works ahead of the shoot. Broadcast dramas have historically been shot close to air, with scripts delivered episodes ahead rather than a season ahead; streaming originals are increasingly fully pre-produced. Either way the writer is delivering scripts during production, which shapes how scripts are written: for a large crew to read fast.

The planning document

The document that starts every drama is the gihoegan, usually translated "planning proposal." Its sections are stable across broadcasters and production companies:

1. Title and logline. One line; often a genre label and a hook.
2. Planning intention (gihoek uido). Why this drama, why now, what it is about beneath the plot. This section carries weight that a US pitch gives to comps and tone; it is where the writer states the theme and the emotional promise.
3. Format. Episode count, length, target slot or platform, genre.
4. Character introductions. A page or so per lead, less for supporting cast; the relationships, often as a chart.
5. Synopsis. The whole story, then an episode-by-episode breakdown with each episode's ending.
6. Sample scripts. Commonly episodes one and two, sometimes up to four. Contests specify.

Broadcasters' annual script contests (KBS, MBC, SBS and others have run them for decades, and cable and streaming players have added their own) accept essentially this package, and they are the traditional path for new writers. Winners are often paired with the broadcaster's drama division. The contests are in Korean.

If you have written a US pilot package, the mapping is close: the planning intention is the "why this show" page, the episode-by-episode synopsis is the season document, and the sample scripts are the pilot plus one. What is different is the emphasis: Korean development weights the whole-series arc and the episode endings more heavily, because the format is a closed miniseries, not an open-ended season.

Format, briefly

Korean scripts do not use the American column layout. A scene is (romanized from the Korean):

S#12. Pyeonuijeom ap – bam

that is, "S#12. Outside the convenience store – night", followed by stage directions (jimun) in prose, then dialogue as name, colon, line, with tags such as (E) for a voice from off-screen, (N) for narration, and (F) for filter/phone. The scripts are written in Hangul word processor (HWP) files, not Final Draft, and formatting is by convention rather than by software. Our K-drama format guide has the full convention with a side-by-side conversion from US format; the short version is that the format is easy to learn and the difficulty is elsewhere.

Structure, briefly

The standard prime-time miniseries has been 16 episodes of roughly 60 to 70 minutes, aired two a week, which produces a rhythm of episode pairs and a set of structural pillars at episodes 4, 8, 12 and 16. Streaming originals run 8 to 12. Every episode ends on a hook, because weekly retention is the format's economics. The 16-episode structure post covers the arc in detail. If you write web serials, the episode-ending hook is the same instrument as the chapter cliffhanger.

Where an international writer realistically fits

Co-development with a Korean writer or producer. The most common route for foreign writers with credits. You bring the concept, the international market sense or the source material; the Korean writer writes the Korean script. Production companies and agencies that work with international partners exist; the relationship is the entry, and it usually starts with a treatment in English and a Korean partner who believes in it.

Adaptation of your IP. Korean dramas adapt web novels, webtoons and, increasingly, foreign novels and formats. If you hold a novel or a format, the route is a rights deal with a Korean production company, and your role afterward ranges from consultant to none. Having a Korean-format treatment prepared helps the conversation; the novel-to-script adaptation post covers producing one.

International co-productions. Streaming platforms commission Korean-language series with international partners, and some projects are developed bilingually. These are rare and go to writers with existing relationships.

Writing in Korean. If you are fluent, the contests and the assistant-writer path are open to you as to anyone. Korean fluency at the level of dialogue, with its register system and the specific rhythms of drama speech, is the actual bar; grammatical Korean is not enough.

What does not work: writing a 16-episode drama in English, translating it, and submitting it to a Korean contest. The translation loses the dialogue, the contests want Korean writers, and the format signals will be off in ways a reader spots on page one.

Working with AI on a K-drama package

AI is useful at the package stage and dangerous at the dialogue stage.

Useful: building the episode-by-episode structure table with pillars and endings; generating character introductions in the planning-document shape; converting prose treatment into S# scenes for a sample episode; checking the episode endings for variety. SparkLore's prompt library has a 16-episode structure prompt and a cold-open prompt built for this, and the free script generator writes a scene in Korean drama format.

Dangerous: Korean dialogue. Models produce grammatical Korean that reads as translated; register (formal, polite, intimate, and the shifts between them that carry drama relationships) is where non-native and machine dialogue both fail. If your Korean is not native, the dialogue in a Korean script needs a Korean writer, full stop. Write the package and the English-language sample; let the collaborator write the lines.

Also: a small number of Korean contests and platforms have introduced rules on AI use, and web novel contests in particular have banned it. Check the rules of any contest before drafting anything with AI; the copyright guide has the platform positions we know of.

What to do this month

1. Watch three recent dramas in your genre with the episode structure in mind: note where each episode ends and what changes at 4, 8 and 12.
2. Write a planning document in English for your idea, in the six sections above, with a 16- or 12-episode breakdown and an ending per episode.
3. Write episode one in Korean format, in English, using the format guide. This is your sample for a Korean partner.
4. Find the partner. Producers, agencies and writers who work internationally; festival markets; the co-production programmes of the streaming platforms. The package is what you bring.

Try it in SparkLore

SparkLore writes and formats Korean drama scripts natively: S# scene numbering, jimun, name-colon dialogue and the tag system, with export to HWP-compatible DOCX and PDF, and it converts prose treatments and web novels into that format. The free AI script generator writes one scene in Korean drama format without an account, and the drama script formatter fixes alignment on a script written as notes. The prompt library has the 16-episode structure table as a form. Sign up to build the whole package in one project; the pricing page has the plans.
