Mouse (2021): Korean thriller story, cast and watch order
Mouse is a 2021 South Korean crime thriller starring Lee Seung-gi and Lee Hee-joon. It follows a rookie police officer and a detective drawn into a serial-killer investigation, using shifting perspectives and withheld information to challenge the audience’s first impressions.
Jung Ba-reum and Go Moo-chi
Lee Seung-gi plays Jung Ba-reum, initially introduced as a conscientious young officer. Lee Hee-joon plays Go Moo-chi, a detective whose personal history gives the investigation an emotional urgency. Their different temperaments are a useful starting point for following the story, but the drama is designed to complicate easy judgments about people.
What to expect without major spoilers
The series combines police procedure with speculative questions about psychology, biology and responsibility. Its scientific premise belongs to a fictional thriller and should not be read as an accurate diagnostic framework. Graphic crimes, trauma and violence make it an adult mystery rather than a light detective comedy.
Watch the main story in episode order
Begin with episode one and follow the numbered drama before seeking explanatory extras or ending discussions. Special presentations associated with Mouse may reframe events and expose answers early. A cast list or recap can itself spoil the mystery, so use spoiler-free summaries until you finish. This guide concerns the Korean television drama, not an animal documentary, a computer accessory or a different film titled Mouse.
