Why are so many K-drama fans spending their weekends in 1932? Because 100 Days of Deception (100일의 거짓말, Baegirui Geojinmal) has quietly become one of the most talked-about Korean shows of the autumn. Kim You-jung plays a pickpocket who goes undercover inside the Japanese colonial government. Park Jin-young, better known to K-pop fans as GOT7's Jinyoung, is the elite interpreter she is not supposed to fall for. The show is halfway through its 16-episode run on tvN, and its ratings keep climbing. This guide covers who is who, when each episode airs in your time zone, how to watch it legally outside Korea, the soundtrack so far, and the real history and places behind the story. All figures are as of November 8, 2026.
Key takeaways
- 100 Days of Deception airs on tvN every Saturday and Sunday at 9:10 p.m. Korea time (KST), one episode per night, from October 10 to a scheduled finale on November 29, 2026. Outside Korea it streams on Netflix in many regions; in Korea it is on TVING.
- Episode 8 set the series high so far at 9.761% nationwide (Nielsen Korea), and the show reached No. 4 on Netflix's global non-English TV chart in the week of October 12-18.
- The story is fiction set against real 1932 history. Two real places connected to the production, the Seoul Museum of History and Dilkusha, are free to visit, and the museum's cast-voiced audio guide runs until November 29.

The story in one minute (no spoilers)
The year is 1932 and the city is Gyeongseong (경성), the name Koreans used for Seoul during Japanese rule; the colonial authorities called it Keijō. Lee Ga-kyung (Kim You-jung) is the city's best pickpocket and a gifted con artist. She is saving every coin for one goal: leaving for America. A resistance group called Gugukdan (구국단) offers her a deal she can hardly refuse. If she spends 100 days undercover as an interpreter trainee at the Government-General, the seat of colonial power, and helps them get to its new Inspector-General, they will help her get out.
Her problem is Kim Tae-woong (Park Jin-young), who also goes by the Japanese name Sato Hideo. He is a brilliant interpreter just back from more than ten years abroad, fluent in Korean, Japanese and English, and the adopted son of the very man the resistance wants dead. Netflix's own one-line summary puts it plainly: Gyeongseong's top pickpocket infiltrates the colonial government to steal secrets, "only to fall for her target's son."
The show runs on that tension. Every conversation is a translation and every translation can be a lie, which is why interpreting sits at the center of the plot rather than in the background. Expect spy-thriller set pieces, a slow-burn romance and a lot of moral pressure on characters who can never say what they mean.

The five leads were confirmed by tvN in February 2026, after casting reports going back to October 2024. Here is who plays whom, based on the Wikipedia cast list and Netflix's title page.
| Actor | Character | Who they are in the story |
|---|---|---|
| Kim You-jung (김유정) | Lee Ga-kyung / Geum Seo-hee | Pickpocket and con artist who goes undercover as an interpreter for 100 days |
| Park Jin-young (박진영, GOT7's Jinyoung) | Kim Tae-woong / Sato Hideo | Elite interpreter at the Government-General, adopted son of Sato Shinichi |
| Kim Hyun-joo (김현주) | Yoo So-ran | Gugukdan sniper who returns under a new identity and offers Ga-kyung the deal |
| Lee Moo-saeng (이무생) | Yoo Phillip | Korean-American correspondent and Gugukdan member in a marriage of convenience with So-ran |
| Jin Seon-kyu (진선규) | Sato Shinichi | The newly appointed Inspector-General and the resistance's main target |
A note on spelling, because it trips up a lot of searches: Netflix and many English outlets write the lead actress's name as Kim You-jung, while others use Kim Yoo-jung. They are the same person. Likewise, the Park Jin-young in this drama is the GOT7 singer-actor born in 1994, not the JYP Entertainment founder who shares his name.
The cast also did unusual homework. According to the production notes collected on Wikipedia, the actors trained with language coaches because the script calls for Japanese, English and Chinese dialogue. Kim You-jung studied Japanese and English for five months, Park Jin-young worked on telling American and British English apart, and Jin Seon-kyu spent two months in Kyoto preparing his Japanese lines.
Behind the camera, director Yoo In-shik made Dr. Romantic and Extraordinary Attorney Woo, and writer Ryu Bo-ri wrote Do You Like Brahms? and Trolley. This is their first project together, and it is a special production marking tvN's 20th anniversary.
Episode schedule and air times
tvN airs one episode each Saturday and Sunday at 21:10 KST. With 16 episodes, the run is eight weekends long. The dates below follow that pattern and match the scheduled finale on November 29 reported by The Week; broadcasters can still shift a date for sports or special programming, so check tvN or your streaming app before a big watch party.
| Weekend | Episodes | Korean air dates (KST) | Nationwide rating (Nielsen Korea) |
|---|---|---|---|
| 1 | 1-2 | Oct 10-11 | 5.278% / 7.605% |
| 2 | 3-4 | Oct 17-18 | 6.991% / 9.044% |
| 3 | 5-6 | Oct 24-25 | 6.538% / 9.515% |
| 4 | 7-8 | Oct 31-Nov 1 | 7.193% / 9.761% |
| 5 | 9-10 | Nov 7-8 | 7.4% / episode 10 airs tonight |
| 6 | 11-12 | Nov 14-15 | Not yet aired |
| 7 | 13-14 | Nov 21-22 | Not yet aired |
| 8 | 15-16 (finale) | Nov 28-29 | Not yet aired |
The pattern is easy to see once the numbers sit side by side: the Sunday episodes have always rated higher than the Saturday ones, and both nights have trended upward. Episode 9 on November 7 was the best Saturday so far, according to MyDramaList's write-up of the Nielsen figures, with a 10.5% peak in the Seoul metropolitan area.
What does 21:10 KST mean where you live? In November, after daylight saving time ends in North America and Europe, the Korean broadcast starts at 7:10 a.m. in New York, 4:10 a.m. in Los Angeles, 12:10 p.m. in London, 8:10 p.m. in Manila and Singapore, and 11:10 p.m. in Sydney. Those are broadcast times in Korea. Netflix has not published an exact upload time for each episode, so it may appear a little later in your app.
How to watch outside Korea
Netflix has a title page for the show (rated TV-14 on its US page), and Netflix's own Top 10 data lists it in country charts as far apart as Indonesia, Saudi Arabia, Nigeria and Peru, so it is clearly available in many regions. JustWatch's US listing shows it on Netflix, including the ad-supported plan. In South Korea itself it airs on tvN and streams on TVING. We have not checked every country, and Netflix is not available everywhere: its help center lists places where the service does not operate at all, including mainland China and North Korea.
- Search "100 Days of Deception" in your Netflix app. If it does not appear, try the Korean title 100일의 거짓말 or the alternative English title "100 Days of Lies".
- Still nothing? Check JustWatch for your country, which lists the legal services that carry it where you live.
- Before you press play, open the audio and subtitle menu and pick your subtitle language. The dialogue switches between Korean, Japanese and English, and those switches carry plot information, so keep subtitles on even in scenes where you think you understand the language.
- Add the show to My List or turn on reminders so new episodes show up on Saturday and Sunday after the Korean broadcast.
- If you are in Korea, use TVING or watch live on tvN. A VPN to reach another region's catalog usually breaks the service's terms, and we do not recommend it.
How popular is it? The real numbers
It is easy to read "hit drama" in a headline, so here are the figures we could actually check. On Netflix's official Top 10 site, 100 Days of Deception ranked No. 4 among non-English TV shows for October 12-18 with 2.8 million views, and No. 8 for October 19-25 with 2.3 million views. It dropped out of the global top ten for October 26-November 1, a week crowded by Lupin, Dead-End Job and Doctor X, but it stayed in Netflix's country top tens in 12 places that week, including No. 3 in South Korea and No. 3 in Indonesia.
At home the trend is stronger. The premiere drew 5.278% nationwide, the best start for a tvN weekend drama in 2026, and episode 8 reached 9.761% nationwide and 10.675% in the Seoul area. Wikipedia's summary of local reports also has it at No. 1 in TVING's weekly rankings for October 19-25 and at the top of Good Data Corporation's drama buzz chart, with Park Jin-young and Kim You-jung first and second among actors. For comparison, SBS's Friday-Saturday drama Doctor X is the bigger ratings hit, at 17.7% nationwide on November 7.
If you followed our Doctor X viewing guide, you will recognize this pattern: Korean hits often build week by week rather than exploding on day one.

The real 1932 Gyeongseong behind the drama
You can enjoy the show without a history lesson, but a little context makes many scenes land harder. Korea was under Japanese rule from 1910 to 1945. The drama's Government-General is the colonial administration, and its headquarters was a real, enormous building. The Government-General Building was built inside the grounds of Gyeongbokgung, the main royal palace of the Joseon dynasty. It served as the colonial seat of power from 1926 to 1945 and was the largest government building in East Asia when it was built. For decades after liberation it was seen as a symbol of imperialism, and it was demolished in 1995-96 so the palace could be restored.
The drama's art team, led by production designer Yang Hong-sam, rebuilt this world through research into period signage, furniture and everyday objects. Its Government-General sets use high staircases, marble and vertical columns to make the colonial administration feel imposing, which matches the photographs of the real building.
Why 1932 matters
The choice of year is not random. 1932 was one of the most dramatic years of the armed independence movement. In January, a member of the Korean Patriotic Organization (한인애국단), a militant group under the Korean Provisional Government in Shanghai, nearly assassinated Emperor Hirohito. On April 29, Yun Bong-gil set off a bomb at a ceremony in Shanghai's Hongkou Park that killed a Japanese general and the head of Shanghai's Japanese residents' association. Yun was executed that December at the age of 24, and he is honored in both South Korea and China today.
The drama's Gugukdan is its own creation, and its characters and plots are fictional. Set against these real events, though, its stakes make sense: in 1932 the idea of resistance cells planning attacks on top colonial officials was not far-fetched.

The journalist detail fans miss
Lee Moo-saeng's Yoo Phillip, the Korean-American correspondent, presses colonial officials by pointing to reporting by Albert Wilder Taylor on the Jeam-ri massacre. Taylor was real. He was an American foreign correspondent in Seoul who broke news of the 1919 March 1st Movement to the world, according to the Seoul Metropolitan Government. His family home, Dilkusha, still stands, and the drama's Heewon residence was inspired by it.
The OST so far
Music director Kim Tae-seong, who scored the show with Choi Jung-in, is releasing the soundtrack in parts. Four singles were out by November 1, and the first will interest K-pop fans most: it is sung by Kim Tae-rae of ZEROBASEONE.
| Part | Song | Artist | Release date |
|---|---|---|---|
| 1 | Together | Kim Tae-rae (ZEROBASEONE) | October 18, 2026 |
| 2 | You | Lee So-ra | October 26, 2026 |
| 3 | Same Old Heart | Luca Minor | October 31, 2026 |
| 4 | Remember Me | So Soo-bin | November 1, 2026 |
Each part was released with an instrumental version, which is handy if you want the score without vocals. With eight episodes left, more parts may follow, but none had been announced in the sources we checked.
Visiting the drama's Seoul

Here is the part we think most fans will enjoy if they are in Seoul this month. Two free sites connected to the drama sit in the same corner of central Seoul, west of Gwanghwamun, and you can pair them with the palace where the colonial headquarters once stood.
Seoul Museum of History (서울역사박물관). The museum hosted the tie-in exhibition "1932 Gyeongseong, Becoming a Spy". The lobby section, with props and furniture used in filming, closed on September 27. The audio guide voiced by Kim You-jung, Park Jin-young, Kim Hyun-joo, Lee Moo-saeng and Jin Seon-kyu, which introduces objects in the third-floor permanent exhibition, runs until November 29, 2026. The museum opens Tuesday to Sunday from 9 a.m. to 6 p.m. (last entry 5:30 p.m.), stays open until 9 p.m. on Fridays, and is closed on Mondays. Admission to the permanent exhibition is free.
Dilkusha (딜쿠샤). Albert and Mary Taylor built this red-brick house in 1923-24; it was rebuilt after a fire, and the Taylors were expelled by the Japanese authorities in 1942. Restored as an exhibition hall and run by the Seoul Museum of History, it opens Tuesday to Sunday, 9 a.m. to 6 p.m. (last entry 5:30 p.m.), is closed Mondays and January 1, and is free. The address is 17 Sajik-ro 2-gil, Jongno-gu. Guided tours in Korean, English and Japanese need a reservation; the museum asks you to call the Dilkusha Information Center (+82-70-4126-8853) a week ahead.

A simple half-day route:
- Start at Gyeongbokgung in the morning. The Government-General Building is gone, but standing near Heungnyemun Gate helps you picture how the colonial headquarters dominated the palace. Our guide to Seoul's free palace entry period has the hours and closed days.
- Walk to the Seoul Museum of History on Saemunan-ro and pick up the cast audio guide for the third-floor galleries. Leave time for the large scale model of Seoul on the same floor.
- Continue to Dilkusha on Sajik-ro 2-gil. Check the map before you go, because the house is tucked into a residential lane rather than on a main road.
- Plan the trip for Tuesday to Sunday. Mondays close both the museum and Dilkusha, and the audio guide ends on November 29.
Want to go further? Wikipedia notes that Nonsan Sunshine Land in South Chungcheong Province, the open-air set used for Mr. Sunshine, was one of the filming locations. In Seoul itself, two buildings from the period still stand: the former Bank of Chosen, now the Bank of Korea Money Museum, and the former Mitsukoshi store, now Shinsegae's main branch.

If the show has made you curious about its stars, these credits are a good place to start. Availability differs by country, so check your local services.
- Kim You-jung: she has played period roles since childhood. Start with Moon Embracing the Sun (2012), where she played the young heroine, then her first starring role in Love in the Moonlight (2016) and the fantasy Lovers of the Red Sky (2021). For something modern, try the fantasy romance My Demon (2023-24) or the psychological thriller Dear X (2025).
- Park Jin-young: his first lead was He Is Psychometric (2019). He gained wider recognition in The Devil Judge (2021) and Yumi's Cells (2021-22), and Our Unwritten Seoul (2025) earned him a Baeksang Best Actor nomination. On film, Christmas Carol (2022) won him the Baeksang Best New Actor award.
- Same creators: Yoo In-shik's Extraordinary Attorney Woo and Ryu Bo-ri's Do You Like Brahms? show both sides of this team's storytelling.

FAQ
How many episodes does 100 Days of Deception have?
Sixteen. tvN airs one each Saturday and Sunday at 9:10 p.m. KST, and the finale is scheduled for November 29, 2026.
Is 100 Days of Deception based on a true story?
No. The characters and the resistance group in the drama are fictional, but the setting is real: 1932 Seoul under Japanese rule, the Government-General Building, and a year of real independence attacks such as Yun Bong-gil's in Shanghai.
Is it on Netflix in my country?
It is on Netflix in many regions, including the US, and it has appeared in Netflix country charts across Asia, the Middle East, Africa and Latin America. Netflix catalogs differ, so search the app or check JustWatch for your country. In South Korea it streams on TVING.
Is Park Jin-young in this drama the GOT7 member?
Yes. He is Jinyoung of GOT7, born in 1994. He is not the JYP Entertainment founder, who has the same name.
Can I still see the drama exhibition in Seoul?
Partly. The lobby exhibition at the Seoul Museum of History ended on September 27, but the cast-voiced audio guide in the third-floor permanent exhibition runs until November 29, 2026.
Our take
100 Days of Deception does something many period dramas avoid: it puts language, translation and lying at the heart of colonial history instead of just using 1930s costumes. Kim You-jung is doing what she has done since childhood, carrying a period drama, and Park Jin-young's quiet, guarded style suits a man who lives between two names. With eight episodes still to go and rising ratings, now is a good time to catch up. Two episodes a weekend means you can finish the first half in a few evenings. If you are in Seoul before November 29, the museum audio guide and Dilkusha turn the drama's world into a free afternoon out.
