“Although it originates from the folklore that "if a rat eats a person's fingernails, it transforms into that person," the drama does not stop at a simple transformation story. It intertwines the pursuit by loan sharks and detectives with the journey of Moon-jae, a novelist who has been stripped of his name, face, and even his life, as he attempts to reclaim his identity.
Netflix Mouse Release Date and Basic Information
*Field Mouse* is a Netflix original series that was released on Friday, August 28, 2026, at 5 p.m. The full story is Total of 10 episodesIt consists of and is released simultaneously to viewers not only in Korea but also around the world.
The genre is a mystery chase thriller. Directed by Kim Hong-sun and written by Lee Jae-gon, the film expands the bizarre premise of the folktale into a modern chase drama.
The core of *The Field Mouse* is the fear that someone does not stop at stealing my face, but can also take away the fact that I am my true self.
The plot of the field mouse and the fable of the mouse that ate fingernails
The starting point is a familiar folktale. Taking inspiration from the story of a mouse that transforms into the same appearance as a person after eating their discarded fingernails, I depicted the 'field mouse' in the work as an unidentified entity that steals the names, faces, and lives of others.
Novelist Moon-jae finds himself in a situation where, after having his life stolen away at a certain moment, he is instead framed as a fake. Moon-jae’s struggle to prove who he is extends beyond identity verification to the issue of reclaiming his memories, relationships, and the entirety of the time he has lived.
The tension created by this premise grows from the question, “If the faces are identical, wouldn’t we be unable to distinguish even real family members?” In the drama, the cloning of appearance from folklore has effectively transformed into a realistic horror that shakes personal information and social trust.
The reason Ryu Jun-yeol's dual role is drawing attention
| person | actor | Tracking purpose |
|---|---|---|
| Moon Jae | Ryu Jun-yeol | Reclaiming the Stolen Name and Life |
| Laozi | Seol Kyung-gu | Recovering lost money |
| Sunyong | Lee Kyu-hyung | Tracking the truth of the case and the identity of the field mouse |
Ryu Jun-yeol took on the role of Moon-jae, for the first time in his acting career playing two rolesI took on this challenge. Rather than exaggerating the two characters to seem like overly different people, I chose an acting style that distinguishes them through subtle differences such as personality texture, gaze, and tone of voice.
In particular, voice serves as an important distinguishing device in scenes where the two characters converse. Since the same actor portrays different characters on the same screen, the subtlety with which differences in facial expressions and breathing are displayed determines the level of immersion in the play.
Ryu Jun-yeol decided to appear in the film after being drawn to the modern reinterpretation of the folktale and the script, which made it difficult to predict the next development. The fact that he personally sought out the original work out of curiosity about the backstory of the piece also suggests that the relationship between Mun-jae and the field mouse sparked strong curiosity in the actor.
The pursuit dynamic between Seol Kyung-gu's Noja and Lee Kyu-hyung's Sunyong
It is not a structure where Moon-jae chases the field mouse alone. No-ja, played by Seol Kyung-gu, is a loan shark who doubles as a private investigator, and he jumps into the case to recover his lost money.
Laozi is a character who acts ruthlessly for money and his goals. Sol Kyung-gu created Laozi's atmosphere by coordinating his costume, makeup, and appearance with the director and production team, and he also took charge of the film's major action scenes.
Lee Kyu-hyung appears as Detective Sun-yong, who pursues the truth of the case. Sun-yong is established as a character with a sharp personality full of anger and dissatisfaction, and for the role, Lee Kyu-hyung Lost about 10kgThe sun has changed its appearance.
Key Viewing Points for *Field Mouse* and the Actors' Preparation
The most striking aspect is that while the three characters pursue the same target, their objectives are completely different. For Munjae, survival and the restoration of his identity are at stake; for Noja, money is important; and for Sunyong, he approaches the truth through investigation.
As the interests of the three intertwine, cooperation and suspicion alternate. Since Sunyong pursues the truth from a separate perspective as a detective while Munjae and Noja follow the case, there is a high possibility that the same scene will be interpreted differently by each character.
The action sequences are also worth mentioning. Sol Kyung-gu portrayed Laozi's rough personality through physical movements, while Ryu Jun-yeol suggested a scene where he is unconscious during the action, participating in a way that suited the character's situation.
Lee Kyu-hyung initially understood Sun-yong as a skilled fighter, rough, and violent character, so he gained weight and bulked up. However, he later lost weight to align with the director's desire for a sharper physique, and he revealed at the press conference that the process was painful.
Things to know before watching Netflix's The Field Mouse
*Field Mouse* is not a work that faithfully reproduces the setting of the folktale, but rather a series that explores modern anxieties surrounding identity and personal information through a thriller. Therefore, rather than how the mouse transforms, the more important question remains: when a person has their life stolen, who do the people around them and society truly accept?.
Ryu Jun-yeol's first dual role, Sol Kyung-gu's loan shark action, and Lee Kyu-hyung's weight loss of approximately 10kg were the key highlights known even before the release. With the addition of the chilling horror and dynamic chase scenes emphasized by Director Kim Hong-sun, viewers who enjoy folklore-based mysteries will find it worthwhile to watch while comparing the motives of each character.
If you want to watch without knowing the ending or the field mouse's identity in advance, it is best to reduce related search terms and start from Episode 1.
