Beyond Sweet Home: 24 Best Completed Horror & Thriller Webtoons to Binge-Watch in 2026

Horror webtoons hit differently. Unlike traditional manga or anime, webtoons use vertical scrolling, sudden reveals, and unsettling pacing to create a far more immersive kind of fear.

And while Sweet Home introduced many readers to the genre, horror webtoons today go far beyond monster apocalypses. Some explore psychological manipulation, serial killers, and social paranoia. Others trap readers inside deadly survival games, cursed towns, or deeply disturbing human experiments. From psychological nightmares to apocalyptic survival stories, this guide collects beyond Sweet Home: 24 best completed horror and thriller webtoons to binge-watch in 2026.

1. Bastard

Where to Read: WEBTOON

Genre: Psychological Horror / Serial Killer Drama

Hook: A quiet high school student wakes up every morning pretending his father is normal—while hiding the fact that a serial killer is living in the same house.

Why It Works: This completed psychological horror webtoon builds its fear through domestic normality. The house looks safe, the father looks kind, but every small action—locking a door, a late-night noise, a forced smile—feels like a potential death signal. The horror slowly shifts from “what will happen” to “how long can I survive this illusion of safety.”

Best For: Fans of psychological thriller webtoons that rely on tension, silence, and emotional manipulation rather than action.

2. Pigpen

Where to Read: WEBTOON

Genre: Psychological Mystery / Survival Thriller

Hook: A man wakes up on a quiet island. The beach is clean, the weather is perfect, and a family welcomes him like they’ve been waiting forever—but he has no memory of who he is, or why everything feels slightly staged.

Why It Works: This completed psychological horror webtoon thrives on controlled confusion. Every conversation feels rehearsed, every smile feels slightly delayed, and every “answer” only deepens the uncertainty. As the story unfolds, reality itself becomes unstable—memories contradict each other, identities blur, and the reader is forced into the same paranoia as the protagonist. It’s not just about solving a mystery; it’s about realizing that the mystery may be designed to keep you trapped inside it.

Best For: Fans of psychological thriller webtoons, unreliable narration, and identity-based mind games similar to Shutter Island or The Truman Show-style paranoia.

3. Stagtown

Where to Read: WEBTOON

Genre: Supernatural Horror / Rule-Based Mystery

Hook: A quiet suburban town looks completely normal at first glance—clean streets, familiar houses, everyday routines—but the longer you stay, the more you notice something subtly wrong with everything you see.

Why It Works: This completed horror webtoon builds fear through gradual distortion rather than overt scares. The town operates under invisible “rules” that no one explains, yet everyone unconsciously follows. Small details—like animals behaving incorrectly, conversations repeating in unnatural ways, or background elements shifting between panels—create a growing sense of unease. The horror is not a single monster or event, but the realization that reality itself is slightly misaligned, and the deeper you look, the more unstable everything becomes.

Best For: Fans of atmospheric horror webtoons, analog horror, creepypasta-style storytelling, and slow psychological tension built through environmental unease rather than direct violence.

4. Surviving Romance

Where to Read: WEBTOON

Genre: Meta Horror / Zombie Survival / Psychological Thriller

Hook: She wakes up as the heroine of a bright, cheerful romance novel—complete with perfect classmates, romantic tension, and a school-life fantasy—until the story suddenly “breaks,” and the world collapses into a full-scale zombie outbreak.

Why It Works: This completed survival horror webtoon stands out because it weaponizes genre expectations. What begins as a familiar reincarnation romance gradually reveals that the world itself behaves like a broken narrative system. Characters who were meant to follow predictable “roles” suddenly lose meaning as the story shifts into survival mode. The horror comes not just from zombies, but from the unsettling idea that people can be reduced to background characters in a collapsing script. It creates a constant tension between emotional attachment and narrative unpredictability, making every chapter feel unstable and dangerous.

Best For: Fans of experimental horror webtoons, zombie survival stories, and genre-deconstruction narratives that constantly challenge reader expectations.

5. Shotgun Boy

Where to Read: WEBTOON

Genre: Survival Horror / Monster Apocalypse / Coming-of-Age Thriller

Hook: A bullied teenager escapes into the forest expecting silence and solitude—only to witness the world outside collapsing into a sudden monster outbreak, forcing him to pick up a shotgun and survive a nightmare he never asked for.

Why It Works: This completed survival horror webtoon works as both an intense standalone story and a prequel to Sweet Home. It contrasts external chaos with internal emotional damage: the protagonist is already broken by bullying before the apocalypse even begins. As the monster outbreak spreads, survival becomes less about fighting creatures and more about confronting fear, guilt, and the sudden power placed in the hands of someone who has never been in control of his life. The pacing is fast, but the emotional weight behind each decision keeps the tension grounded.

Best For: Fans of monster apocalypse webtoons, action-driven survival horror, and emotionally layered prequel stories connected to the Sweet Home universe.

6. Dear X

Where to Read: WEBTOON

Genre: Psychological Thriller / Social Horror / Crime Drama

Hook: A nationally beloved actress appears flawless on camera—polished smile, perfect image, and an untouchable reputation—while behind the scenes, she quietly manipulates, discards, and destroys anyone who stands in her way.

Why It Works: This completed psychological thriller webtoon builds its horror through control, image, and emotional manipulation rather than physical violence. The protagonist doesn’t hide from society—she understands it too well, using admiration itself as a weapon. Every relationship becomes transactional, every smile feels calculated, and every success is built on invisible collateral damage. The deeper tension comes from watching how easily cruelty can exist behind public perfection, especially in an industry that rewards illusion over truth.

Best For: Fans of social thrillers, morally ambiguous antiheroes, and stories like Gone Girl or The Glory that explore hidden violence behind polished public images.

7. Melvina's Therapy

Where to Read: WEBTOON

Genre: Psychological Horror / Surreal Art Horror / Trauma Narrative

Hook: A therapy session begins like any other—calm, clinical, controlled—until the patient is asked to confront their deepest fear not as a memory, but as something they are forced to physically experience.

Why It Works: This completed psychological horror webtoon transforms therapy into a descent into symbolic nightmare logic. Instead of explaining trauma, it reconstructs it visually—warping bodies, environments, and emotions into surreal sequences that feel more like intrusive dreams than narrative events. The horror is not always linear or literal; it emerges from discomfort, fragmentation, and the sense that emotional pain has taken physical form. Each arc feels like stepping into a different psychological space, where meaning is implied rather than stated, making the experience linger long after reading.

Best For: Fans of experimental horror webtoons, surreal psychological storytelling, and visual horror styles similar to Junji Ito or abstract nightmare fiction.

8. Uriah

Where to Read: WEBTOON

Genre: Psychological Horror / Survival Drama / Crime Thriller

Hook: A boy wakes up injured, disoriented, and stripped of identity—thrown into a world where survival is immediate, and remembering who you are might be more dangerous than staying lost.

Why It Works: This completed psychological horror webtoon focuses on degradation rather than escape. Instead of offering clear answers or safe ground, it steadily strips away identity, dignity, and emotional stability. The horror is grounded in human cruelty, institutional violence, and the slow erosion of selfhood under pressure. As the story progresses, survival becomes less about escaping danger and more about enduring a world that continuously reduces people to disposable objects. Its tone remains relentlessly heavy, making it one of the most emotionally punishing entries in modern webtoon horror.

Best For: Fans of extremely dark psychological thriller webtoons, survival stories with no comfort, and narratives centered on human collapse and moral decay.

9. Hell Is Other People

Where to Read: WEBTOON

Genre: Urban Psychological Horror / Claustrophobic Thriller / Social Paranoia

Hook: A young man moves into a cheap, cramped apartment in Seoul, expecting a fresh start—until he realizes the thin walls don’t just carry sound, they carry something far more invasive: the constant feeling of being watched.

Why It Works: This completed psychological horror webtoon turns everyday urban life into a pressure cooker of paranoia. The apartment becomes a closed system where privacy slowly disappears, and every neighbor feels like a potential threat. Small, ordinary moments—footsteps in the hallway, a glance through a doorway, an unexplained noise at night—gain a threatening weight as distrust spreads. The horror doesn’t rely on supernatural forces, but on psychological erosion: the fear that you can never truly know who is on the other side of the wall, or what they might already know about you.

Best For: Fans of claustrophobic horror webtoons, slow-burn psychological thrillers, and urban paranoia stories set in realistic modern environments.

10. Distant Sky

Where to Read: WEBTOON

Hook:The sky over Seoul has collapsed into endless darkness. No stars, no sunlight, no horizon—just an infinite void swallowing the city while two teenagers try to survive inside what’s left of the world.

Why It Works: This completed apocalypse webtoon builds its horror through absence rather than action. The environment itself becomes the antagonist: collapsed buildings fade into black, distance loses meaning, and even silence feels heavy. As the characters move through a world without light or orientation, survival becomes psychologically draining—each step forward feels less like progress and more like drifting deeper into uncertainty. The story gradually shifts from physical survival to existential endurance, asking what it means to keep going in a world that no longer resembles life.

Best For: Fans of bleak, atmospheric survival horror webtoons, existential storytelling, and visually experimental apocalypse narratives.
