Korean Dramas Have a 'Summer' — How to Read That Screen from a Country Without Four Seasons

Viki's editors picked six romance dramas for summer viewing. But in Korean drama, summer isn't a backdrop — it's a narrative device. Here's how it reads where seasons don't change.

🇰🇷 Korea·August 8, 2026·10 min read

Last Summer, a summer drama, was shot between September 2024 and February 2025 and premiered on 1 November 2025.

It was not summer when they filmed it and not summer when it aired.

Seasons in Korean drama do not come from the calendar. They are assembled on screen, and the job that assembled season does is not decoration. It is a clock. Miss it and half the story goes by unread.

Only two of the six actually aired during summer. Columns two and four do not agree, and the question the table leaves open is the one that matters: if the season on screen is neither the broadcast date nor the shooting date, when exactly is it?

All six sit on Viki, picked one apiece by Soompi and Viki editors as romances to watch in summer. Summer Strike runs 12 episodes with Seolhyun and Im Si-wan, following a woman who quits her job and moves to a seaside town. Last Summer has Lee Jae-wook playing twin brothers in a dual role alongside Choi Sung-eun and Kim Gun-woo. Be Melodramatic follows three thirty-something friends working in television, and Coffee Prince, the 2007 entry with Gong Yoo and Yoon Eun-hye, was adapted from a romance novel of the same name and extended from 16 episodes to 17 on the strength of its reception.

Korean summer is 118 days long and still growing

Before the screen, measure the actual season. Over the most recent 30-year normal period (1991–2020), summer is the longest season in Korea at 118 days.

Tropical nights per year4.1 (1973–1982)12.2 (2016–2025)3.0×

Every unit in that table is a day. The unit a drama works in is the shot. How 118 days get compressed into a handful of cuts is not something meteorological statistics can tell you.

The monsoon has become hard to tabulate at all. The Korea Meteorological Administration stopped announcing official start and end dates for jangma, the summer rainy period, in 2008, and formally retired the term "monsoon front" in 2021. The 2020 rainy period ran a record 54 days; 2021 and 2025 were over in about two weeks. Even Koreans have stopped treating summer rain as predictable.

Assuming a summer drama was shot in summer is a mistake

Last Summer began filming in September 2024 and wrapped in February 2025. The summer scenes were captured in early autumn; the rest was shot in winter. Broadcast came in November and December.

Korean production practice manufactures that gap. Three modes are mixed in the industry: fully pre-produced series shot before broadcast, partial pre-production where roughly half is in the can when the show goes to air, and live-shoot production that starts one or two months before airing and continues throughout the run. Global streaming's appetite for simultaneous release has pushed pre-production upward, and with it the distance between camera and screen.

So the summer you see is not a record of a summer. It is a reconstruction — chosen foliage, layered cicada audio, a change of wardrobe. Which is precisely why it feels more consistent than the real thing. What survives on screen is a summer more summer-like than any actual July.

Cicadas are not ambience, they are a subtitle

Pull one ingredient out and the method becomes visible.

A Korean malmaemi cicada calls at 80 to 100 decibels. Eighty decibels is roughly a subway train pulling into a station. Surveys by the National Institute of Biological Resources found cicada density in central Seoul running about ten times higher than in rural Gyeonggi Province, because urban heat raises both survival and reproduction rates. Cicadas normally call only in daylight; Seoul is bright enough at night that they call before dawn.

When a cicada track comes up under a scene in a Korean drama, two things arrive at once — the season is summer, and the hour is the middle of the day. Two subtitles' worth of information, delivered without a line of dialogue.

Other materials work the same way.

  • The sudden downpour — arrives without warning, gone in twenty minutes. This is where two people end up stuck under an eave with one umbrella
  • School uniforms and summer break — why coming-of-age stories choose summer. Time outside school is easy to stage, and light clothing dates a period clearly
  • Electric fans and air-conditioner units — the heat indoors and the household's finances in a single frame
  • The sea and the mountain valley — the signal that a character has left the city

It is no accident that Twinkling Watermelon travels back to 1995 and Lovely Runner to a high-school past with summer as the setting. Vacation creates time outside the classroom, and light clothing makes the decade legible at a glance.

A change of season is a time skip without a caption

The most important function comes last. In Korean drama, season marks the passage of time.

If two people part in summer and meet again in winter, no caption reading "six months later" is required. The leaves and the coats already carry that information. Snow means time has passed; cherry blossom means something is starting over.

This grammar only works where four seasons are sharply drawn.

Speech level marks a change in relationship the way season marks a change in time, and both tend to evaporate in subtitles — so what exactly does the speech-level layer lose? The moment honorifics disappear from the subtitles asks the same question on the language side.

What this means where you are

Most of Southeast Asia divides the year into wet and dry rather than four seasons. Trees stay green year round and wardrobes barely change. The same frames therefore read differently.

On screenWhat it means in KoreaWhat to do with it
Falling leaves or snowMonths have passedDo not file it under "the mood shifted." A season change is an uncaptioned time skip
Cicadas on the soundtrackMidday in summer — also a standard flashback cueIf the sound enters abruptly, check whether the scene has moved into the past
Two characters caught in a downpourRain that stops in twenty minutes. It works dramatically because it is shortDifferent in kind from monsoon rain. Brevity is the point
Uniforms with no school in sightSummer vacationA quiet marker of when in the year you are
"This is our last summer"Korean summer is 118 days; the other 247 are not summerWhere it is hot all year, that ache does not arrive on its own. Knowing the number changes the weight of the line
You are in Vietnam, Thailand or IndonesiaThe onset and end of the rains do the work four seasons do in KoreaMap the first rains and the end of the dry season onto Korea's early and late summer and the cue lands

One practical caution. All six titles sitting on the same platform is convenient, but service territories and subtitle languages differ country by country. Appearing on a list is not the same as being watchable in your country in your language. Viki in particular licenses title by title and region by region.

Summer has grown twenty days longer while the summers on screen stay short. If the frame ever catches up with the climate, will summer still be the season everyone is sorry to lose?
