Kim Mo-mi is an ordinary office worker who, deeply insecure about her looks, leads a secret double life as “Mask Girl” — a popular masked livestreamer who performs for an anonymous online audience hungry to adore her. By day she endures quiet humiliations and an unrequited crush on her boss. By night she builds a following she can only keep by hiding her face. When a spiral of obsessive fans, brutal violence, and an exposed identity shatters everything she has built, the consequences don’t stop with Mo-mi — they ripple outward for decades.

Told across seven episodes in the voices of different characters — Mo-mi’s stalker, his fiercely devoted mother, a wronged friend, and the daughter born from tragedy — Mask Girl is not a story about one woman’s fall. It is a story about what happens to the people left standing in the wreckage. Adapted from the webtoon series by Maemi and Hee Se, and written and directed by Kim Yong-hoon (Beasts Clawing at Straws).

📺 Episode Guide

Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.

Mask Girl Episode 1 — Kim Mo-mi
EP 01
Kim Mo-mi
August 18, 2023
Kim Mo-mi grew up dreaming of becoming a pop star, but her plain looks shattered those ambitions early. By day she toils at a dull office job, nursing a secret crush on her married boss and enduring the quiet cruelties of pretty colleagues. By night she becomes Mask Girl — hiding her face on a livestream where strangers finally adore her. When an emotional breakdown during a broadcast exposes her misery to a viewer she doesn’t realize is her own co-worker, her carefully divided life begins to crack.

Mask Girl Episode 2 — Ju Oh-nam
EP 02
Ju Oh-nam
August 18, 2023
Episode 1 rewinds — this time through the eyes of Ju Oh-nam, a socially isolated loner who has identified Mask Girl as Mo-mi from the distinctive moles on her hands and has been quietly stalking her. When a wealthy fan attempts to assault Mo-mi at a motel, Oh-nam intervenes and kills the man — then helps Mo-mi dispose of the body. Traumatized, Mo-mi quits her job and undergoes plastic surgery to start over. Oh-nam tracks down her new address, breaks in, and rapes her. Mo-mi stabs him to death in self-defense.

Mask Girl Episode 3 — Kim Kyung-ja
EP 03
Kim Kyung-ja
August 18, 2023
The perspective shifts to Kim Kyung-ja — Oh-nam’s fiercely overprotective mother who spent her entire life sacrificing for her son. When Oh-nam goes missing and police discover a decomposed body in his apartment, then his own remains in a suitcase, Kyung-ja is consumed by grief and a burning need for justice. The public exposure of Mask Girl as Oh-nam’s murderer gives her a target. Her obsessive investigation leads her to track down a woman she believes to be Mo-mi — and she takes her at gunpoint.

Mask Girl Episode 4 — Kim Chun-ae
EP 04
Kim Chun-ae
August 18, 2023
The woman Kyung-ja abducted is not Mo-mi — she is Kim Chun-ae, Mo-mi’s closest friend, bound to her by a shared history of being ostracized for their looks and reinventing themselves through surgery. Under duress, Chun-ae lies to protect Mo-mi. When Mo-mi arrives to help, the friends are cornered by Kyung-ja in a chaotic standoff: Kyung-ja shoots Chun-ae, who manages to bludgeon Kyung-ja before dying. Mo-mi, believing Kyung-ja dead, dumps both bodies in a lake — then surrenders herself to police.

Mask Girl Episode 5 — Kim Mi-mo
EP 05
Kim Mi-mo
August 18, 2023
Years pass. Mo-mi’s baby daughter Mi-mo grows up with her maternal grandmother, relentlessly bullied at school for being “Mask Girl’s daughter.” Angry and isolated, Mi-mo transfers schools and forms an intense friendship with Ye-chun, a fellow outsider who harbors deeper feelings for her. The two girls plan to run away together — until Mi-mo discovers her identity has been exposed at her new school and furiously blames Ye-chun. In reality, the leak comes from Kyung-ja — who survived her injuries, now lives in disguise, and has positioned herself outside Mi-mo’s school, quietly closing in.

Mask Girl Episode 6 — Kim Mo-mi (Prison Years)
EP 06
Kim Mo-mi (Prison Years)
August 18, 2023
Inside prison, Mo-mi navigates a brutal hierarchy before reaching a fragile peace with the powerful inmate Ahn Eun-suk. Years into her sentence, she receives an anonymous letter from Kyung-ja — who has survived and is systematically dismantling Mi-mo’s life from the outside. Mo-mi attempts a desperate prison escape that fails, earns solitary confinement, and then offers to donate a kidney to Eun-suk’s daughter as leverage for goodwill. Kyung-ja visits Mo-mi directly and reveals her long game: she intends for Mo-mi to suffer the precise agony of losing a child — the same grief Kyung-ja has never escaped.

Mask Girl Episode 7 — Mi-mo and Mo-mi
EP 07 · Final
Mi-mo and Mo-mi
August 18, 2023
Mi-mo, estranged from Ye-chun and her grandmother, has moved in with Kyung-ja — whom she loves as a grandmother figure, unaware of the woman’s true identity or intentions. When Kyung-ja attempts to strangle Mi-mo to death on a live broadcast, Mo-mi escapes from a hospital where she had been taken for the kidney operation. Racing to Kyung-ja’s house alongside Ye-chun and Mi-mo’s grandmother, the three arrive in time to stop the killing. But Kyung-ja stabs Mi-mo’s grandmother fatally before police can intervene — and as she raises her gun toward Mi-mo, Mo-mi throws herself in front of the bullet, dying in her daughter’s arms while Kyung-ja is shot by police. In the aftermath, Mi-mo is taken in by Ye-chun’s family. She watches an old home video of her mother as a young girl performing at a talent show — and for the first time sees Mo-mi not as a criminal but as a human being who only ever wanted to be loved. The nightmares stop.

🏁 Ending Explained

What actually happened — and what the finale is really saying.

The ending of Mask Girl isn’t really about resolution — it’s about inheritance. Mo-mi dies protecting the daughter she barely knew, in the same way that everything in this series has cascaded: one act of violence or longing producing consequences that outlast the person who caused them. Kyung-ja’s decades-long plan of revenge collapses not because it was wrong to want justice, but because the person she was punishing had long since become a different woman — and the person she was targeting to cause that pain was a child who did nothing to deserve it. The show never exonerates Mo-mi. But it asks whether destruction without end is still justice, or just another form of obsession.

Mask Girl (2023) Episode 6 — Kim Mo-mi Prison Years

Mi-mo surviving is deliberately bittersweet. She has lost her grandmother, she will carry the knowledge of what her mother did, and she has now watched a woman die to save her. But she ends up with Ye-chun’s family — people who chose her — and she ends up watching her mother before any of the violence happened: a young girl on a stage, performing, wanting to be seen. That is the image the show wants to leave you with. Not the mask, not the blood, not the prison cell. The girl who just wanted an audience, who never got one she could actually trust. The nightmares stop because Mi-mo has finally seen the human being rather than the headline. That’s the show’s version of mercy.

As for Kyung-ja — the show’s most morally complex figure — her arc ends with her surviving the police shooting but losing everything she devoted herself to. She is not framed as a monster; she is framed as a mother whose grief curdled into something she could no longer control. Yeom Hye-ran’s performance ensures that even in Kyung-ja’s final act of attempted murder, there is something heartbreaking beneath the rage. Mask Girl trusts its audience enough to hold all of this simultaneously — sorrow, condemnation, and reluctant understanding — without collapsing into comfort or easy moral conclusions. Watch it for Yeom Hye-ran, stay for the structure, and let the ending sit with you longer than you expect it to.

✍️ KDramaWorlds Editor’s Take

Our honest read on why this drama is worth your time — and who it’s for.

🖤 Dark Noir🪞 Identity & Masks🔪 Uncompromising🌊 Cascading Consequences💔 Generational Pain

What makes Mask Girl genuinely extraordinary — and genuinely difficult — is that it refuses to let you settle. Most K-dramas with a morally grey lead still provide a ledge to hold onto: a mentor figure, a redemptive romance, a final act that reassures you the show knows right from wrong. Mask Girl offers none of those handholds. Kim Mo-mi is not a good person; she is a deeply human person, shaped by a world that consistently treated her as less than. The show’s structural gambit — telling the same story from four different perspectives, each one reframing and deepening what came before — is not a gimmick. It is the only way to tell this story honestly. By the time you reach Episode 7, you have inhabited the minds of a stalker, a grieving mother, and a betrayed friend. You understand all of them. You cannot fully condemn any of them. And that is exactly where the discomfort lives.

Mask Girl (2023) — cinematic still

The divisive element — and it is genuinely divisive — is the graphic sexual violence in Episode 2. The rape is not gratuitous in the sense of being extended or fetishized, but it is shown with enough clarity that many viewers found it traumatic and some felt the narrative did not adequately reckon with it afterward. This is a fair criticism. The show is more interested in the downstream consequences of Mo-mi’s actions than in dwelling on what was done to her, and that asymmetry is uncomfortable. Whether that’s a flaw or a deliberate provocation about how society processes female victims is a question Mask Girl leaves open. What it does not leave open is Yeom Hye-ran. Her performance as Kim Kyung-ja is one of the finest in any K-drama of 2023 — a woman of absolute conviction and absolute grief, whose love for her son became the most destructive force in the series. The show would be compelling without her. With her, it becomes something you cannot shake. Internal links: if you liked the multi-perspective structure, Juvenile Justice works similar moral territory from an institutional angle; if you want another Netflix dark female-led, My Name is the closest cousin in tone.

The seven-episode runtime is both Mask Girl’s greatest asset and its only real liability. It moves with the economy of a miniseries that knows exactly how many hours it has — no filler, no drag. But the finale does feel compressed. Episode 7 resolves threads that deserve more time, particularly the Mi-mo and Ye-chun relationship, which the show sets up with genuine care but pays off in a rush. That said, the final image — Mo-mi as a little girl on a stage, performing for a crowd that is finally, finally watching — is devastating in the best way. Watch it for Yeom Hye-ran, stay for the structure, and let the ending sit with you longer than you expect it to.

⚖️ Final Verdict
What works
Three actresses, one seamless soul — Ko Hyun-jung, Nana, and Lee Han-byeol never feel like separate people
Yeom Hye-ran as Kyung-ja — one of the year’s most devastating supporting performances
Multi-perspective structure that genuinely deepens rather than just complicates
Unflinching social commentary on beauty, obsession, and disposable women

What to know first
Episode 2 contains a graphic rape scene — not gratuitous, but not softened either
No likeable protagonist — Mo-mi is sympathetic but not innocent
Episode 7 finale is slightly rushed — some threads resolve too quickly
Heavy content throughout: violence, assault, bullying, graphic death

7.6 / 10Watch it for Yeom Hye-ran and stay for the structure — this one will follow you out of the room.
