100 Days of Deception: Kim You Jung and Park Jin Young's Period Spy Thriller Hits Netflix October 10

Netflix's Next Big K-Drama Is a Genius Pickpocket Turned Spy

Mark your calendars, K-drama fans — 100 Days of Deception is officially landing on Netflix worldwide on October 10, 2026. And honestly? It might be the most exciting period drama of the fall.

Directed by Yoo In Shik and written by Ryu Bo Ri, this romantic-action thriller stars an absolutely stacked cast including Kim You Jung, Park Jin Young, Kim Hyun Joo, and Jin Seon Kyu. It's the kind of lineup that makes you clear your whole weekend the second the first episode drops.

What's 100 Days of Deception About?

Set during the Japanese occupation of Korea, the story follows Lee Ga Gyeong (Kim You Jung), a genius pickpocket who gets recruited to work for the independence army. Her mission? Go undercover as a spy inside the Japanese Government-General itself.

Here's the twist — she doesn't actually plan to be a good spy at first. Ga Gyeong intends to fake her way through it to get what she wants. But somewhere along the way, she starts feeding the independence army genuinely crucial intel, and the line between fake spy and real resistance fighter starts to blur.

Meanwhile, Park Jin Young plays Kim Tae Ung (also known as Sato Hideo), a character whose loyalties are just as murky. When a master pickpocket and a man living under a false identity keep crossing paths, the tension is basically off the charts.

The Cast and the Premiere Schedule

Kim You Jung is no stranger to Netflix hits — she's already starred in My Demon, Chicken Nugget, Backstreet Rookie, and 20th Century Girl. Park Jin Young, meanwhile, led Our Unwritten Seoul and When My Love Blooms before landing this one.

Rounding things out: Kim Hyun Joo (from Hellbound and The Bequeathed) plays Yoo So Ran, Jin Seon Kyu (of The Uncanny Counter and Vincenzo fame) takes on the role of Sato Shinichi, and Lee Moo Saeng (The Glory, Gyeongseong Creature Season 2) joins as Yoo Philip.

• Total episodes: 16
• Release schedule: Saturdays and Sundays on TVN, streaming the same on Netflix
• Runtime: ~70 minutes per episode
• Finale: November 29, 2026

Why You Should Be Hyped

If you loved the moody, high-stakes energy of Gyeongseong Creature or the clever cat-and-mouse pacing of The Scandal, this one's clearly in your wheelhouse. A pickpocket running a long con against an occupying government, with a romance simmering underneath — it's a setup that almost writes itself.

Plus, with Yoo In Shik behind the camera (known for his sharp, stylish direction), you can expect some seriously slick action sequences mixed with the kind of quiet, tense character moments that make period K-dramas so addictive.

Final Thoughts

October is shaping up to be a heavy month for K-drama fans on Netflix, and 100 Days of Deception is easily one of the most anticipated titles. Between the elite cast, the historically charged setting, and that spy-vs-spy love story, it has all the ingredients to be one of 2026's biggest streaming hits.

Set your reminder for October 10 — this is one undercover mission you won't want to miss.
