Basis and Development
Mask Girl is based on the Naver Webtoon of the same name, written by Maemi and illustrated by Hee-se, serialized from August 15, 2015, to June 9, 2018. The original work delves into themes of identity and duality, following a protagonist who navigates societal pressures related to her appearance by leading a secretive double life as an office worker and a masked online performer.[2][5] The adaptation rights were secured by production companies House of Impression and Bon Factory to develop the story as a Netflix original series. Kim Yong-hoon was brought on board as both writer and director, representing his debut in television following the success of his 2020 feature film Beasts Clawing at Straws.[2][6] During pre-production, the creative team opted for a concise 7-episode miniseries format to preserve tight pacing and narrative momentum, transforming the webtoon's black comedy elements into a broader thriller structure with suspenseful twists. A pivotal decision involved casting three distinct actresses—Lee Han-byeol for the young, pre-surgery phase; Nana for the post-surgery period; and Go Hyun-jung for the prison stage—to visually and performatively embody the lead character's evolving identities and life transformations.[2][7][6]Casting and Filming
The casting for the lead role of Kim Mo-mi in Mask Girl involved open auditions held in 2022, culminating in the selection of three actresses to portray different phases of the character's life: rookie Lee Han-byeol for the young, pre-plastic surgery stage, selected from a competitive 1000:1 audition process that impressed director Kim Yong-hoon and the original webtoon authors; K-pop idol Nana (Im Jin-ah) for the office worker phase following the character's murder and transformation; and veteran actress Go Hyun-jung for the prison phase.[8][2][9] Key supporting roles were announced in February 2022, with Ahn Jae-hong cast as Ju Oh-nam, Mo-mi's co-worker and a fan of her masked persona, bringing his experience from prior dramatic roles to the production.[10][11] Yeom Hye-ran was cast as Kim Kyung-ja, Oh-nam's mother, following her acclaimed performances in projects like The Glory (2022–2023), where she earned praise for her versatile supporting turns.[10][9] Principal photography took place from February to September 2022 across South Korea, primarily in Sejong—utilizing practical locations such as neighborhoods, streets, Sejong Lake Park, and the Sejong City Office of Education for office and urban scenes—and Goesan County in North Chungcheong Province for additional sequences, with some interiors shot on sound stages to depict cam sessions and prison environments.[12][2] One notable production challenge was coordinating the schedules of the three lead actresses to maintain continuity across Mo-mi's transformative phases, a logistical hurdle highlighted by Go Hyun-jung as an intriguing "3 people, 1 role" dynamic that demanded precise alignment in performance and timing.[13] While specific COVID-19 protocols for Mask Girl were not detailed publicly, the 2022 filming aligned with industry-wide measures in South Korea, including testing and masking on set amid ongoing pandemic restrictions.[14] Post-production, including editing to support the series' non-linear narrative structure, was completed by late 2022, with visual effects for masked sequences and other enhancements handled by Dexter Studios to integrate the distinct portrayals of the protagonist seamlessly.[15][2]Cast and Characters
Principal Cast
Lee Han-byeol portrays the young adult Kim Mo-mi, an insecure office worker harboring dreams of stage performance from her childhood while leading a secret life as the masked camgirl Momi. A newcomer to acting, Han-byeol makes her debut in Mask Girl, delivering a performance that authentically conveys Mo-mi's vulnerability, suppressed angst, and determination in her initial phase of self-doubt.[2][16][17] Nana (Im Jin-ah) plays Kim Mo-mi in her transformed phase as the beautiful A-reum following plastic surgery, navigating a dual existence that amplifies her camgirl persona Momi amid newfound confidence and external pressures. Formerly a member of the K-pop group After School, Nana entered acting with her debut role in the 2016 remake The Good Wife and gained prominence in the 2017 film The Swindlers. Her portrayal seamlessly extends Mo-mi's arc, emphasizing the character's shift from insecurity to assertiveness while underscoring the illusions of identity change.[2][18][19] Go Hyun-jung depicts the imprisoned Kim Mo-mi, embodying her hardened, resilient persona shaped by incarceration and loss. A veteran actress who rose to stardom with her acclaimed portrayal of the ambitious Lady Mishil in the 2009 historical drama Queen Seondeok, which earned her multiple awards including the Grand Prize at the MBC Drama Awards, Go infuses the role with profound depth and emotional intensity.[2][20][17] Ahn Jae-hong stars as Joo Oh-nam, Mo-mi's awkward coworker and eventual love interest, whose unrequited admiration for her intertwines with his fandom of Momi. Recognized for his comedic prowess in the 2019 series Be Melodramatic, where he played the eccentric director Son Beom-soo, Ahn brings nuance to Oh-nam's peculiar blend of loneliness, obsession, and tentative affection.[2][21] Through these distinct portrayals, the principal cast highlights Mo-mi's evolving identity across non-overlapping phases of her life—from youthful insecurity and transformation to hardened survival—effectively mirroring the series' themes of self-perception and reinvention without narrative redundancy.[18][22]Supporting Cast
Yeom Hye-ran plays Kim Kyung-ja, the grieving mother of Joo Oh-nam, whose quest for justice drives key emotional conflicts in the story.[2] Her portrayal captures the raw intensity of maternal loss and rage, earning praise for its depth and contributing to the series' exploration of revenge.[23] Yeom previously gained recognition for her role in the Netflix series The Glory (2022–2023), where she depicted a complex supporting character in a bullying narrative.[23] Lee Jun-young appears as Choi Bu-yeong in episode 4, embodying an antagonistic figure that heightens tension through confrontational dynamics.[24] The actor is known for his versatile action-oriented performances, including the lead role in the film Brave Citizen (2023), a vigilante thriller. His brief but impactful presence in Mask Girl underscores the series' episodic escalations of conflict. Other notable supporting performers include Moon Sook as Sim Yeong-hui, Kim Mo-mi's mother, who provides grounding family context amid the protagonist's turmoil; Shin Ye-seo as Kim Mi-mo, Mo-mi's daughter, whose storyline advances themes of inherited stigma and bullying; and Han Jae-yi as Kim Chun-ae, a rival and ally who aids in pivotal escape sequences.[25] These roles collectively propel subplots related to familial bonds, law enforcement pursuits, and personal rivalries, bolstering the black comedy elements by adding layers of irony and pathos without dominating the central narrative.[26]Plot and Episodes
Synopsis
Mask Girl is a South Korean miniseries that centers on Kim Mo-mi, a young office worker in Seoul plagued by insecurity over her appearance due to rigid societal beauty standards. By day, she endures a monotonous corporate routine, but by night, she transforms into the enigmatic masked camgirl known as "Mask Girl," streaming performances that garner a devoted online following and allow her to embrace a hidden spotlight she once dreamed of as a child.[2] This double life, adapted from the Naver webtoon of the same name by Maemi and Hee-se, spirals into chaos when unforeseen violent incidents force Mo-mi to confront the perils of her anonymity and the blurred lines between her real and virtual personas.[2] The narrative unfolds in a non-linear fashion, weaving through distinct phases of Mo-mi's life—from her early years and professional struggles to periods of isolation and reinvention—employing flashbacks to gradually unveil the events that reshape her identity.[27] This structure, spanning decades and multiple actors portraying the protagonist at different stages, builds a puzzle-like tale of transformation amid escalating personal crises.[27] Throughout the series, themes of online notoriety clash with real-world pressures, including workplace bullying and buried family truths, infusing the story with black comedy through increasingly outlandish developments like desperate cover-ups and identity shifts.[1] As a seven-episode miniseries without additional seasons, it culminates in a tense arc of retribution and introspection, highlighting the consequences of Mo-mi's quest for validation.[3]Episode Guide
