Identity TheftLoan SharkWebtoon AdaptationReclusive WriterPsychological Suspense

Je Moon-jae has spent years disappearing into his own fiction, a reclusive novelist who’d rather write about the world than live in it. Then someone erases the boundary entirely: a figure known only as The Rat steals his name, his face, and his entire financial existence, leaving Moon-jae unable to prove he is who he says he is. Mousetrap turns that identity theft into a hunt, forcing him into an alliance with No-ja, the loan shark who’s been chasing Moon-jae’s debt for years and now has more reason than anyone to help him get his life back.

Netflix has built a real track record with this exact register — the mismatched-duo crime thriller where neither party trusts the other but circumstance won’t let them walk away. Ryu Jun-yeol and Sul Kyung-gu read as an inspired pairing on paper: a man who’s lost every external marker of who he is, teamed with someone whose entire job is finding people who don’t want to be found. Ten episodes, one premiere date, and a premise built on the very Korean-thriller instinct that identity is never as fixed as it looks.

✍️ KDramaWorlds Editor’s Take

Worth the watch? Our honest answer, and who it’s aimed at.

🐀 Identity Stolen 💰 Loan Shark Ally 🕵️ Mistaken Identity Chase 📖 Webtoon Origins

Mousetrap’s premise does something K-thrillers rarely commit to fully: it strips its protagonist of every external proof of self before the story even starts. Moon-jae isn’t framed for a crime or forced into hiding, he’s erased, his name and fortune handed to someone else while he’s left arguing with a system that has no category for ‘the real person.’ It’s a sharper hook than the genre’s usual chase plot, closer in spirit to the identity-under-siege dread Mouse built its psychological thriller around than to a straightforward heist or revenge plot.

Mousetrap (2026) — cinematic still

Pairing him with No-ja is the smarter structural choice — a loan shark who’s spent years treating Moon-jae as a debt to be collected now has to treat him as a client to be protected, and that reversal only works if both actors sell the discomfort of it. Netflix has proven with titles like Mask Girl that Korean thrillers built around a stolen or hidden self can go to genuinely unpredictable places once the premise stops being a gimmick and starts being the engine.

Ryu Jun-yeol playing someone stripped of agency is an interesting swing against his usual charismatic-lead type, and Sul Kyung-gu rarely takes a role he doesn’t commit to fully. Whether Mousetrap earns its 10-episode runtime or front-loads its best ideas into the premiere is the open question heading into August 28.

⚖️ Final Verdict
What works
A genuinely fresh hook — losing your identity entirely, not just your freedom
Ryu Jun-yeol and Sul Kyung-gu’s casting suggests real chemistry potential in an adversarial-turned-allied dynamic
Director Kim Hong-seon’s atmospheric pedigree (Dear Hongrang) is a good sign for tone and pacing

What to know first
Anticipation Pick — no episodes have aired yet, so tone and pacing are still unknowns
Full season is expected on Netflix, so plan for a binge rather than a weekly watch
Webtoon adaptations vary widely in how much of the source’s mystery mechanics survive the screen

Anticipation Pick— A premise built on real dread: what happens when the system simply stops recognizing you as yourself.
