Monster ApocalypseSurvival HorrorWebtoonNetflix Original

Cha Hyun Su has nothing left to lose. A lonely high school dropout with no family, no future, and no will to live, he moves into Green Home — a rundown apartment complex where broken people seem to collect. He plans to end things quietly. Then the building starts producing monsters. Not outside, not from some distant threat, but from within the residents themselves: neighbors, strangers, and people who were just trying to get through the day, transforming into nightmarish creatures defined by their most obsessive desires. The glutton who couldn’t stop eating. The man whose grief curdled into something unrecognizable. Each monster is a portrait of a human need gone horribly wrong.

What makes Hyun Su’s situation uniquely terrifying is that he isn’t immune — he’s something worse. Infected but not fully transformed, he exists in a no-man’s land between human and monster, gaining superhuman abilities while fighting his own darkest impulses. Together with a desperate, fractious group of survivors including ex-firefighter Seo Yi Kyung and the cold, enigmatic Pyeon Sang Wook, Hyun Su must figure out what it actually means to want to stay alive — and whether a person like him deserves to.

📺 Episode Guide

10 episodes — spoiler-light recaps of every chapter.

Sweet Home Season 1 Episode 1 — Green Home
EP 01
Green Home
December 18, 2020 · Netflix
A flash-forward shows Hyun Su amid some kind of battlefield. Weeks earlier, he moves into Green Home after losing his entire family — a fragile, suicidal loner looking for a place to disappear. He witnesses his neighbor transform into a ravenous “glutton” monster, and a blood-sucking creature attacks the ground floor residents. Lee Eun Hyuk and Seo Yi Kyung seal the building. The outside world is already overrun.

Sweet Home Season 1 Episode 2 — Nosebleed
EP 02
Nosebleed
December 18, 2020 · Netflix
Flashbacks reveal the car crash that killed Hyun Su’s family and left him the sole survivor. Back in the present, it surfaces online that nosebleeds and auditory hallucinations are early signs of monstrous transformation. Burglar Pyeon Sang Wook kills the glutton but is bitten in the process. A terrified Hyun Su rescues two orphaned siblings from a monster — and starts experiencing the very symptoms he’s been warned about.

Sweet Home Season 1 Episode 3 — Lights Out
EP 03
Lights Out
December 18, 2020 · Netflix
A power outage plunges Green Home into darkness, and Hyun Su’s monstrous urges surface — but he fights them back and discovers he has superhuman regenerative abilities. Resident Im Myung Sook briefly transforms to subdue a hulking “protein” monster threatening the orphans, then reverts to human form — the first hint that the line between monster and human isn’t fixed. Yi Kyung restores power in the basement but is ambushed. A national broadcast shows even the president beginning to transform.

Sweet Home Season 1 Episode 4 — Half-Monster
EP 04
Half-Monster
December 18, 2020 · Netflix
A military broadcast confirms that transformation is triggered by intense desire, not infection. An unseen force hurls Hyun Su from the ninth floor — he survives, exposing his hybrid nature to the other residents. Store owner Kim Suk Hyun demands his expulsion, but Hyun Su isn’t the only one showing symptoms. Im Myung Sook, meanwhile, has fully transformed into a dormant, fetus-like creature — something no one knows how to handle.

Sweet Home Season 1 Episode 5 — The Predator
EP 05
The Predator
December 18, 2020 · Netflix
Eun Hyuk sends Hyun Su and Sang Wook upstairs together — an uneasy partnership. Sang Wook uncovers evidence that neighbor Choi Yoon Jae is a child predator, confronts him, and beats him to death before dragging the body outside. The survivors hold a quiet funeral for those lost. Yi Kyung discovers she is pregnant after finding a test in the ruins of the building. Hyun Su continues taking on dangerous missions for the group, each one testing how much of himself he still controls.

Sweet Home Season 1 Episode 6 — Fire and Ash
EP 06
Fire and Ash
December 18, 2020 · Netflix
Flashbacks flesh out Sang Wook’s backstory: an intentional fire killed his father, driving him to become a contract killer in pursuit of revenge. In the present, abused wife An Seon Yeong kills her monstrous husband Kim Suk Hyun in a rare act of reclaimed agency. As food and water run low, Eun Hyuk plans an evacuation and tasks Hyun Su with scouting the underground parking lot. Yi Kyung independently leaves the complex and discovers that the government has been secretly experimenting on people — and is captured by the military.

Sweet Home Season 1 Episode 7 — Outside
EP 07
Outside
December 18, 2020 · Netflix
Under military interrogation, Yi Kyung reveals Hyun Su’s hybrid ability — and is sent back into the building as a spy fitted with a tracker. Inside, Ji Su collapses with appendicitis and Eun Hyuk performs improvised emergency surgery. A supply run outside goes immediately wrong when the enlarged protein monster ambushes the team. Flashbacks reveal Hyun Su’s history: severe school bullying drove him to depression and a suicide attempt — recontextualizing everything about his character.

Sweet Home Season 1 Episode 8 — Jung Ui Myeong
EP 08
Jung Ui Myeong
December 18, 2020 · Netflix
The supply team battles the protein monster outside. Gil Seob sacrifices himself to let the others escape with the supplies — Ji Su’s surgery ultimately succeeds. The entity known as Jung Ui Myeong emerges more prominently: a sentient monster who inhabits human bodies and displays a predatory intelligence far beyond the other creatures. Tensions inside the building sharpen into something uglier, as fear, distrust, and differing survival philosophies push the survivors toward open conflict.

Sweet Home Season 1 Episode 9 — Closing In
EP 09
Closing In
December 18, 2020 · Netflix
Yi Kyung’s conflicted loyalty reaches a breaking point as military forces begin closing in on Green Home. Jung Ui Myeong, posing as a human, infiltrates the remaining survivors and begins manipulating them from within. The group makes a desperate final push to prepare for evacuation. Hyun Su’s hybrid nature intensifies — his ability to transform at will begins to fully manifest — and the other survivors must decide whether to trust him or fear him.

Sweet Home Season 1 Episode 10 — What We Keep
EP 10
What We Keep
December 18, 2020 · Netflix
Green Home falls. Jung Ui Myeong reveals his full lethal nature and turns on the survivors, killing several in chaos. The military extracts the remaining residents — but identifies Hyun Su as a research target rather than a survivor. Overwhelmed by his own transformation, Hyun Su willingly disappears into the ruined outside world to protect those he’s come to care for. Sang Wook departs on his own path. Yi Kyung escapes military custody. Eun Hyuk ensures the orphans are evacuated safely. The finale closes on a deliberately open note: the monster crisis is far from over, and Hyun Su walks away transformed, alone, and uncertain — setting up Season 2 directly.

🏁 Ending Explained

Full spoilers ahead — everything that happens in the finale and what it all means.

⚠️
Spoiler Warning — This section covers the full finale of Sweet Home Season 1. Stop here if you haven’t finished the series.

Green Home doesn’t survive. The finale tears apart whatever fragile community had formed inside the apartment complex. Jung Ui Myeong — the sentient monster who has been quietly wearing human faces all season — drops the pretense and turns on the survivors directly. People die. The military breaches the building. What was meant to be a rescue operation turns into something more complicated and more sinister: the soldiers are extracting useful subjects, not saving people.

Sweet Home Season 1 (2020) Episode 9 — Closing In

Hyun Su’s fate is the most layered resolution in the finale. He is not rescued — he is flagged as a research asset because of his unique ability to exist between human and monster without fully becoming either. Rather than let himself be captured and studied, he chooses to disappear. He walks away from the building, away from the people he’s come to care about, and into a devastated world outside — monstrous in form but still choosing, still deciding. It’s an ending that refuses to define him as hero or monster.

Each supporting character gets a different kind of closure. Sang Wook, whose entire arc this season has been about pursuing a private revenge rather than collective survival, continues alone on his own terms. Eun Hyuk — the level-headed organizer who held the group together — ensures the orphans and remaining survivors are evacuated safely before the building falls. Yi Kyung, who spent most of the season caught between the military and the people she’d grown close to, escapes military custody and disappears into uncertainty, pregnant and on the run.

Sweet Home Season 1 (2020) Episode 5 — The Predator

The monsters in Sweet Home were always about desire, not biology. Every creature in this series is a portrait of a human need left unchecked — hunger, grief, loneliness, obsession. What the finale argues is that Hyun Su’s resistance to full transformation isn’t a superpower. It’s the result of something harder: he genuinely doesn’t know what he wants badly enough to become a monster for it. The suicidal teenager who moved into Green Home at the start had already let go of his desires. That emptiness, paradoxically, became his protection.

The ending lands deliberately open. Jung Ui Myeong survives. The government’s involvement remains unexplained. The monster crisis hasn’t been resolved — it’s been displaced. Eun Yu’s grief over Eun Hyeok is left hanging, unresolved. The show isn’t interested in clean conclusions because it was never really about defeating the monsters outside. It was always about the ones inside. Season 1 ends the way it begins — with Hyun Su walking alone in a ruined world, the only difference being that this time, he’s choosing to be there.

✍️ KDramaWorlds Editor’s Take

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

🩸 Visceral Horror🏚️ Ensemble Survival🌑 Psychological Dark💊 Human vs Monster

Sweet Home Season 1 arrived in December 2020 and immediately established itself as something Korean horror hadn’t quite delivered on Netflix yet — a full-throttle monster apocalypse with serious emotional stakes. Lee Eung Bok, who previously directed Goblin and Mr. Sunshine, brings a cinematic scale to the carnage that most streaming horror forgets to earn. Each monster in Green Home isn’t just a creature-feature set piece — it’s a psychological portrait, a human need literalized and weaponized. The show understands that the most terrifying thing isn’t the transformation itself but what the transformation reveals about the person who couldn’t contain their own desires. Song Kang’s Hyun Su is a genuinely unusual K-drama lead: not charming, not particularly heroic, and actively suicidal at the start. His arc — from someone who has nothing left to lose to someone who chooses to survive specifically because of others — is the emotional engine the whole series runs on.

Sweet Home Season 1 (2020) — cinematic still

Where Sweet Home earns its reputation is in the ensemble. The building’s survivors are a genuinely disparate group — a former firefighter, a contract killer, a child abuse victim, two orphaned siblings — and the drama is smart enough to give most of them actual interiority rather than just role-filling. Lee Jin Wook’s Sang Wook is the standout: a character who operates entirely on his own moral code, refuses to pretend he cares about collective survival, and somehow becomes one of the most compelling presences on screen because of it. The flip side is that All of Us Are Dead — which arrived two years later — arguably improved on this exact formula, giving its ensemble sharper character definition and more consistent pacing throughout. Sweet Home’s middle episodes do drag, and the government conspiracy subplot that surfaces in Episode 6 never pays off with the clarity it promises.

The finale is divisive for a reason. It doesn’t resolve — it disperses. Characters scatter, the monster threat continues, and the most satisfying emotional thread (Hyun Su’s decision to vanish rather than be weaponized) is more thematically coherent than dramatically cathartic. If you come to Sweet Home for a complete story, you’ll finish Season 1 feeling unfinished. If you come for what it actually delivers — an immersive, beautifully shot, emotionally serious monster horror that uses its webtoon source material with surprising fidelity — it holds up completely. Four years on, it remains the benchmark for Korean monster horror on streaming.

👍👍👍 BEST FOR 👍👍👍
🩸 Horror fans who want emotional stakes with the gore
🏚️ Ensemble survival drama watchers (Squid Game crowd)
📖 Webtoon fans who want faithful, serious adaptations

⚖️ Final Verdict
What works
Song Kang’s breakthrough — a genuinely unconventional K-drama lead
Monsters as psychological portraits of human desire
Lee Jin Wook’s Sang Wook — morally autonomous and unforgettable
Cinematic production quality — Lee Eung Bok’s direction elevates the material

What to know first
Episodes 5–7 drag — pacing becomes uneven mid-season
The finale doesn’t conclude — it’s a setup for Season 2
Heavy gore — not for viewers with low horror tolerance
Three seasons exist — commitment required to see the full arc

7.8 / 10Watch it — the monster design and emotional core make it essential K-drama horror, even if the finale leaves you wanting more.
