A successful novelist suddenly loses his name, money, home, and even the ability to prove who he really is. The person responsible is simply known as “The Rat,” and finding him becomes the only way for the writer to get his life back.
That is the strange setup of Netflix’s new Korean thriller Mousetrap. Starring Ryu Jun-yeol and Sul Kyung-gu, the 10-episode series mixes identity theft, mystery, crime, and psychological tension into a story that becomes increasingly complicated as it moves forward.
But after all 10 episodes were released at once, one question has started appearing among K-drama fans: is Mousetrap actually worth watching, or is it better to skip?
What Is Mousetrap About?
Je Moon-jae (Ryu Jun-yeol) is a successful novelist who has lived almost completely isolated from society for several years. A traumatic incident from his childhood left him struggling with severe panic disorder, and he has built his entire life around staying inside his luxurious apartment.
His carefully controlled routine suddenly falls apart when his phone stops recognizing his fingerprint, and he discovers that he cannot access his bank account. His only close friend, who has been handling many parts of his life, also suddenly disappears.
Moon Jae soon discovers something much worse.
Someone has stolen his identity, taken control of his property and money, and is living under his name. Even more frighteningly, Moon-jae struggles to convince other people that he is actually the real person.
His search eventually brings him face to face with No-ja (Sul Kyung-gu), a ruthless loan shark who has been looking for Moon-jae because of an unpaid debt. No-ja initially sees him as nothing more than a debtor, but the situation changes when he realises that Moon-jae may also be the victim of a much bigger scheme.
The two men form an unlikely partnership and begin searching for the mysterious person known as "The Rat". Meanwhile, Detective Park Sun-yong (Lee Kyu-hyung) investigates the strange chain of events surrounding Moon-jae and No-ja.
Why Are Viewers Interested in Mousetrap?
The biggest strength of Mousetrap is easily its premise. Identity theft is nothing new, but the drama takes the idea much further by asking what happens when someone does not simply steal your money or information, but effectively takes over your entire existence.
Moon-jae has spent years avoiding the outside world, so watching him suddenly forced into unfamiliar situations adds another layer to the mystery. He has to deal with people who do not believe him, while trying to understand how someone could have prepared such an elaborate plan.
The partnership between Moon-jae and No-ja is another reason viewers have stayed interested. Their personalities could not be more different, and neither man completely trusts the other.
But There Is One Big Problem
The biggest criticism surrounding Mousetrap is its pacing.
Several viewers felt that the drama takes too long to move its central mystery forward. The first episode spends considerable time establishing Moon-jae's isolated life and showing his confusion after his identity disappears, while N-ja and Sun-yong remain more mysterious in the beginning.
Some viewers enjoyed this slow build because it allowed the paranoia to grow gradually. Others felt that the story could have been shorter, particularly during the middle episodes where certain developments and revelations begin to feel repetitive.
One Reddit discussion described the series as average and felt that the 10-episode format stretched the story, while another viewer who finished the entire drama praised its storytelling, unusual ending, and the fact that it offered something completely different from the usual romance-focused K-dramas.
So, the pacing seems to be the biggest dividing point among viewers.
Watch It or Skip It?
The answer depends largely on what you expect from the drama.
Watch it if you enjoy slow-burn Korean thrillers, unusual mysteries, strong performances, and stories where it is difficult to tell who can actually be trusted. The central identity theft idea is interesting enough to keep the mystery alive, and the pairing of Ryu Jun-yeol and Su Kyung-gu gives the series much of its personality.
Skip it if slow pacing quickly loses your interest or if you prefer thrillers that constantly introduce new action and major revelations. Some viewers felt that Mousetrap repeats certain ideas instead of moving forward as quickly as the premise promises.
Overall, Mousetrap seems to work best when treated as a psychological mystery rather than a fast crime thriller.
Where and When to Watch Mousetrap
Mousetrap premiered on August 28, 2026, exclusively on Netflix. The limited series has 10 episodes, with all episodes released together, making it possible to binge the entire mystery in one go.
The drama stars Ryu Jun-yeol as Je Moon-jae, Sul Kyung-gu as No-ja and Lee Kyu-hyung as Detective Park Sun-yong. It is directed by Kim Hon-sun and written by Lee Jae-gon.
Mousetrap is based on the Korean webtoon Field Mouse (Deuljwi) by Ludvico. The drama keeps the original story's central idea of an ordinary person's identity being taken from him and builds it into a darker crime mystery.
Final Thoughts
Mousetrap is not a perfect thriller, and the mixed reactions make that pretty clear. Some viewers found the pacing frustrating, while others became increasingly invested as the mystery unfolded.
What makes it worth discussing, however, is that it takes a simple question, “What if someone stole your identity?” and turns it into something much darker.
If you have already watched Mousetrap, do you think it is worth recommending, or does the slow pacing make it a skip?
