The School Nurse Files

The School Nurse Files (보건교사 안은영) is a six-episode South Korean fantasy series released on Netflix on 25 September 2020, adapted from Chung Serang's award-winning 2015 novel School Nurse Ahn Eun-young. Chung co-wrote the scripts with director Lee Kyoung-mi, making the show an unusually direct translation of a novelist's imagination to screen. Ahn Eun-young (Jung Yu-mi) is a school nurse born with an inconvenient gift: she sees the residue that living things leave behind — desires, moods, grudges and spirits — as multicolored "jellies" that squirm, cling and occasionally kill. Her weapons are a toy sword and a plastic gun, and her job is less nursing than quiet, unglamorous pest control.

Posted to Moglyeon High School, Eun-young finds a campus sitting on something old and hungry, and a faculty that mostly cannot see the problem. Her one ally is Chinese-language teacher Hong In-pyo (Nam Joo-hyuk), heir to the school's founding family, whose body radiates a protective energy field that recharges her when the work drains her dry. Around them circle a group of students and colleagues who complicate the simple monster-of-the-week arithmetic: a bullied boy chasing a shortcut to power, a transfer student who calls herself a mite-eater, and the enigmatic teacher Mackenzie, who can see the jellies too and does not appear to mind them.

Across six episodes the show swings between deadpan school comedy, body-horror grotesquerie and something closer to a fable, gradually widening from campus incidents to an outside interest — the organization Safe Happiness — with designs on the land the school is built on. It is a series about the exhausting, thankless labor of care: about people who can see what everyone else refuses to, and who keep swinging a plastic sword anyway.

At heart, the series is an argument about guje — the Korean idea of rescuing others from trouble — and its cost. Eun-young's ability is framed not as a superpower but as an obligation she never asked for, a chronic condition that isolates her, tires her out and pays nothing. The show asks what it means to be born responsible, and whether a person is permitted to want freedom from a duty only they can perform.

Underneath the gelatinous CGI is a very grounded thesis: desire is not evil, but unattended desire festers. The jellies are the ordinary emotional exhaust of adolescence — loneliness, envy, lust, shame, ambition — and they become monstrous only when they are hoarded, exploited or ignored by adults who prefer not to look. The institution (the school, the corporation, the family legacy) is repeatedly shown as the thing that manufactures monsters and then hires one underpaid woman to clean up after them.

Finally, it is a story about connection as a power source. Eun-young cannot sustain the work alone; In-pyo's hand is literally her battery. Against a slick corporate entity named "Safe Happiness," the show offers a messier proposal — that safety and happiness are not products to be bought or land to be seized, but things two tired people generate by holding on to each other.

Fantasy or psychological portrait? The most common alternative reading treats the jellies as metaphor rather than fact — the visual language of a woman who perceives emotional truth too acutely to function normally, with In-pyo as the person who chooses to believe her rather than pathologize her. Under this reading the finale's ambiguity is the point: nothing is ever definitively confirmed to anyone but Eun-young.

Arriving in September 2020 as one of Netflix's early Korean original series, The School Nurse Files mattered less for ratings than for what it signaled about the streamer's Korean strategy: that Netflix would fund work too odd for terrestrial broadcast. A six-episode, effects-heavy fantasy adapted from a literary novel, co-written by that novel's author and directed by a woman with an arthouse résumé, was not something the traditional Korean network system was likely to greenlight.

Its most durable legacy is as a showcase for auteur weirdness in the K-drama space. Lee Kyoung-mi — a Park Chan-wook protégée whose credits include Crush and Blush and The Truth Beneath — treated the series as an experiment, and the result reads as a bridge between Korean genre cinema's grotesque-comic tradition and the episodic streaming format. Critics repeatedly reached for words like trippy, bewildering and bonkers; some outlets celebrated it as a visual and social statement, praising how the jelly conceit let the show talk about bullying, adolescent desire and institutional exploitation without lecturing.

Culturally, the series sits inside a Korean fascination with the idea of guje — saving people from trouble — and with school as a pressure cooker where hierarchy, competition and cruelty are the water everyone swims in. The recasting of an exorcist as a salaried school employee with a plastic sword is a specifically Korean joke about labor and duty. Reception was genuinely split: an IMDb score around 6.3 and a Rotten Tomatoes audience score in the low seventies capture a show that some viewers adored for its texture and others abandoned for its opacity. It never received a second season, and its unresolved finale remains its most-discussed feature.

Reception was sharply divided, and the split was consistent from launch onward. Aggregate numbers land the series in mixed-positive territory — roughly 6.3 on IMDb and a Rotten Tomatoes audience score around 73% — which understates how polarized individual responses were. Viewers tended either to fall hard for the show's texture or to bounce off it within two episodes.

Praised: originality above all. Reviewers described it as intriguing and weird in the most refreshing way, bonkers but entertaining, and a visual and social achievement. The blend of dark comedy with genuine grotesquerie was widely admired, as was the CGI jelly ecology — the guardian whale, the moss jellies at the basketball game, the toad-monster — which most found expressive rather than cheap. Jung Yu-mi drew near-universal praise: she was repeatedly said to steal the show, giving a quiet, spiky, mean-funny performance that supplies energy to a character who could easily read as drab. Nam Joo-hyuk's In-pyo, written as deliberately monotonous and dorky, was credited with lending subtle charm and warmth.

Criticized: pacing and clarity. The dominant complaint is that six episodes were not enough — that the story felt rushed, that the mythology was never adequately explained, and that the finale was a mess, leaving the fate of the monsters, of In-pyo and of Safe Happiness unaddressed. Some found the first episode's monster effects the weakest in the show, and several reviewers described the experience as bewildering in a way that shaded from pleasurable into frustrating.

Verdict: a cult object rather than a hit. Opinion over time has softened toward affection — the series is now often recommended precisely as the strange, unrepeatable thing it is — but the consensus remains that a brilliant premise and a magnetic lead performance were underserved by a truncated episode count and an ending that stopped rather than concluded.
