Will There Be a ‘Mousetrap’ Season 2 on Netflix? Here’s What We Know So Far

Netflix’s newest Korean thriller just dropped, and viewers are already binging their way through its twisted identity theft mystery. ‘Mousetrap’ premiered on the streamer, and fans hooked on its cat and mouse chase are already wondering whether a second season is coming.

The series follows a reclusive novelist whose life is stolen out from under him, and the ending leaves plenty of threads that could easily be pulled into another season. Here is everything currently known about the future of ‘Mousetrap’.

What Is ‘Mousetrap’ About?

‘Mousetrap’ is a South Korean mystery thriller written by Lee Jae-gon and directed by Kim Hong-sun, based on the Kakao webtoon Field Mouse by Ludovico. The story centers on Mun-Jae, a reclusive novel writer, who is unable to unlock his own cellphone one day and discovers that his sole friend has vanished.

Mun-Jae soon realizes that a mysterious figure known only as Rat has taken everything from him, including his name, his identity, and his property. Director Kim Hong-sun has said the story was inspired by a classic Korean folktale premise, the idea that a rat becomes human after eating fingernails, which he wanted to blend with genuine psychological dread and genre thriller suspense.

To reclaim his stolen life, Mun-Jae tracks down loan shark No-Ja, a calm and dangerous man who runs a private detective agency and has been searching for Mun-Jae for three years over an old debt. The unlikely pair end up joining forces, and their partnership becomes the emotional backbone of the series as the hunt for the Rat escalates.

‘Mousetrap’ Cast and Characters

The stolen-identity thriller stars Ryu Jun-yeol as Moon-jae, Sul Kyung-gu as No-ja, and Lee Kyu-hyung as Sun-yong, a detective who joins the hunt for the Rat. Ryu Jun-yeol described Moon-jae as a man who had lived in isolation.

Ryu Jun-yeol, known for ‘Reply 1988’, and Sul Kyung-gu, known for ‘Hyper Knife’, headline the cast as two very different men whose lives are manipulated by the same veiled figure. In December 2024, it was first reported that Ryu Jun-yeol and Sul Kyung-gu were in talks to star in the series, and by May 2025 both actors were confirmed to lead the cast.

The supporting cast also includes Kim Sung Oh as Seung Gyu, Hyun Bong Sik as Myung Su, and Moo Jin Sung as Son Su Hyeon, described as Mun Jae’s friend. Both lead actors tend to work more in film than television, with Sul in particular spending decades as one of Korean cinema’s most reliable character actors, which makes pairing him opposite Ryu in a cat and mouse premise feel like a notable swing for the production.

‘Mousetrap’ Release Details

‘Mousetrap’ was scheduled for release on Netflix on August 28, 2026. The series runs for 10 episodes with a duration of around 50 minutes each, and carries an 18 plus content rating for violence and profanity.

The project was first unveiled in January 2026 as part of Netflix Korea’s 2026 slate and was originally announced for a third quarter 2026 release window before Netflix confirmed the specific August date by the end of July 2026. Principal photography began in the first half of 2025, and additional supporting cast members Moon Jong-il and Go Hyung-woo joined the project in December 2025.

‘Mousetrap’ arrives in a fairly crowded August for Korean television, landing alongside ‘Flex X Cop’ Season 2 on Disney Plus and ‘Our Sticky Love’ on Netflix. That kind of competition means ‘Mousetrap’ will need strong buzz and word of mouth to stand out in the algorithm, which matters a great deal for how quickly Netflix might greenlight another round.

Will There Be a ‘Mousetrap’ Season 2

As of right now, Netflix has not announced any plans for a second season of ‘Mousetrap’. That is not unusual, since the streamer typically waits for viewership data before making a renewal call on any of its Korean original series.

Early reviews have described the series as slick but somewhat sluggish, which suggests critical reception so far has been mixed rather than a slam dunk. A tepid critical response does not automatically kill a show’s chances, since plenty of Netflix Korean dramas have overperformed with audiences despite lukewarm reviews, but it does mean the pressure is on the show’s viewership numbers in its crucial first weeks.

Given that ‘Mousetrap’ was just unveiled as part of Netflix Korea’s broader 2026 slate, the streamer clearly has confidence in the property and the pairing of Ryu Jun-yeol and Sul Kyung-gu. Whether that translates into a season 2 will likely depend on how the show performs on the global Top 10 charts over its first month.

For now, viewers should treat ‘Mousetrap’ as a self-contained mystery until Netflix says otherwise, though the show’s premise leaves plenty of room for the Rat’s story to continue if the numbers cooperate. If you have already finished the season, what do you think should happen to Moon-jae and No-ja if the hunt for the Rat continues into a second chapter.
