Mousetrap: Ryu Jun-yeol and Sul Kyung-gu Face Off in Netflix's Can't-Miss August Thriller

Netflix Just Scheduled Its Most Anticipated K-Thriller of the Summer

Identity theft is scary enough on paper — but imagine waking up one morning and your phone refusing to recognize your face. That's the nightmare hook of Mousetrap, the new Netflix thriller shaping up to be one of August 2026's biggest streaming drops. Scheduled for August 28, the series marks the first-ever pairing of Korean powerhouses Ryu Jun-yeol and Sul Kyung-gu — and K-drama Twitter is already losing it.

Based on the Kakao webtoon Field Mouse by Ludovico and directed by Kim Hong-sun with a script by Lee Jae-gon, Mousetrap follows a reclusive writer named Mun-jin. One morning, his identity is systematically stolen: his phone won't unlock, his accounts are gone, and somewhere out there, a mysterious man known only as The Rat is living his life — and burning whatever's left of it to the ground.

Ryu Jun-yeol & Sul Kyung-gu: The Dream Pairing

Mun-jae is played by Ryu Jun-yeol, who's been stealing hearts since Reply 1988 and recently bent reality in Netflix's mind-bending survival hit The 8 Show. As the world stops recognizing him, his quiet desperation becomes the show's beating heart.

On the other side: Sul Kyung-gu — one of Korea's most respected screen veterans, known for The Whirlwind and Kingmaker — as No-ja, a calm, dangerously patient loan shark who happens to run a private detective agency on the side. Here's the twist: No-ja has been hunting Mun Jae for three years, ever since the writer borrowed money from him and vanished. So when Mun's identity collapses, his only ally is the one man who's been looking for him all along. To get his life back, the writer and the shark must work together to track down The Rat — while The Rat keeps pulling strings from the shadows.

Why It's the Must-Watch of August

• A fresh formula: not another serial-killer romance — an identity heist with a living, breathing victim.
• Two giants, first collision: Ryu Jun-yeol and Sul Kyung-gu share the screen for the very first time.
• Webtoon pedigree: Field Mouse earned a cult following on Kakao before adaptation.
• Perfect season slot: it lands right alongside Our Sticky Love, Flex X Cop Season 2, and My Bias, My Boss for the Korean content summer.

How to Stream It

Mousetrap is expected to premiere globally on Netflix on August 28, 2026, with all episodes released at once — ideal for a weekend binge. If you vibed with the paranoia of The 8 Show or the political head of The Whirlwind, mark the calendar.

One thing is certain: nobody in Mousetrap wakes up feeling like themselves by episode eight. It's shaping up to be the knife of the K-thriller summer — absolutely unmissable. 🍿
