The best thriller manhwa keep you scrolling because something is closing in: a monster on the next floor, a neighbor who knows too much, a detective one step behind. This list ranks ten series by that kind of tension (survival, confinement, crime and pursuit) and leaves the mind-game titles to our best manhwa psychological thriller list.
Updated October 28, 2026: We rebuilt this list around tension. Lookism, Weak Hero, Blood Blade and Study Group are action series and have moved out; so has Random Chat, which is a school drama (see the correction above). New entries: Hell is Other People, Pigpen, A Killer Paradox, Money Game (The 8 Show), All of Us Are Dead, and COPYCAT, which is still running. Bastard now lives on the psychological thriller list only. Every status below was checked on the official platform page and AniList on October 28, 2026.
TL;DR: Start with Sweet Home for survival horror, Hell is Other People for a creeping neighbor story, and Vigilante or A Killer Paradox for crime. COPYCAT is the one still running, with a new English episode each week. Nine of the ten are completed.
What this list covers (and where Bastard went)
Thriller manhwa gets lumped together with horror, action and mystery. Here, a series earns a place when the pressure comes from a threat the characters can't walk away from. The ten picks fall into four kinds of tension:
- Survival: Sweet Home, All of Us Are Dead
- Confinement and suspicion: Hell is Other People, Pigpen
- Crime and pursuit: Vigilante, A Killer Paradox, COPYCAT
- Games with rules: Money Game (The 8 Show), Dice
Killing Stalking (captivity) is the adult outlier at the end of the list.

Bastard (94 chapters, completed in 2017) is the title most thriller lists open with, and it deserves that. Its engine is psychological, a boy covering for his serial killer father, so it is the #1 pick on our psychological thriller list and we don't repeat it here. If you've read it and want more from the same writer, Sweet Home, Pigpen and COPYCAT below are all Carnby Kim stories, and manhwa like Bastard has more. If what you actually want is a puzzle to solve, not just dread to sit with, our best manhwa mystery detective picks are narrower on purpose: solving something has to be the plot, not just a tagged theme.
Best thriller manhwa: key takeaways
- Sweet Home (141 chapters, completed in 2020, WEBTOON) is the first pick: one building, a handful of residents, and monsters inside the walls.
- Hell is Other People (88 chapters, completed in 2018) and Pigpen (68 chapters, completed in 2020) are the best confinement thrillers: the danger is the people you live with.
- COPYCAT is the only ongoing pick. English Episode 30 went up on October 27, 2026, and WEBTOON lists it weekly under Wednesday.
- Six of the ten have live-action adaptations: four on Netflix, one on Disney+ and one on OCN.
- Killing Stalking (71 chapters, completed, Lezhin) is marked adult on AniList; graphic violence and abuse warnings apply.
The 10 best thriller manhwa
Sweet Home cover art.
1. Sweet Home
Chapters: 141 | Story / art: Carnby Kim / Youngchan Hwang | Platform: WEBTOON (app; free access varies) | Status: Completed (2017 to 2020)
After a family tragedy, a reclusive high school student moves into a run-down apartment building just as its residents begin turning into monsters. Sweet Home ranks first because its setting does the work: there is nowhere to go, the survivors don't trust each other, and the threat can come from the person in the next room.
Netflix adapted it in three seasons (December 2020, December 2023 and July 2024). The webtoon itself is one 141-chapter story, so you don't need the show to follow it. Sweet Home review → | Sweet Home reading guide →
2. Hell is Other People
Chapters: 88 | Story / art: Yong-Ki Kim | Platform: WEBTOON (app; free access varies) | Status: Completed (2018)
Jongu Yun is in his 20s, short on money, and rents a cheap room in a dilapidated Seoul building whose residents are creepy from day one. Then mysterious things start happening, and he begins to suspect the neighbors are more than odd. The tension here is slow and domestic: every trip down the hallway is a risk, and the story keeps you unsure how much the residents already know about him. It became the OCN drama Strangers from Hell in 2019.
Pigpen cover art.
3. Pigpen
Chapters: 68 | Story / art: Carnby Kim / SICK | Platform: WEBTOON (app; free access varies) | Status: Completed (2019 to 2020)
A young man wakes up on a beautiful beach with no idea who he is or how he got there, and the family that takes him in is not what it seems. Pigpen is the Carnby Kim story that most depends on not knowing: every clue leads to more questions, and the calm of the place is the threat. Read it before anyone spoils the twist.
Vigilante cover art.
4. Vigilante
Episodes: 141 | Story / art: kim kyusam / CRG | Platform: WEBTOON (app; free access varies) | Status: Completed (2018 to 2021)
When Jiyong Kim was a boy, his mother was murdered, and her killer served three and a half years. Seventeen years later Jiyong is a college student studying to become a police officer, and on weekends he hunts ex-convicts the courts let go. The series works as a moral argument, not as validation of its premise: the police are competent, the hero's choices have consequences, and the story asks whether extra-legal violence can be ethical without settling the question cheaply.
Disney+ released an eight-episode live-action version in November 2023.
5. A Killer Paradox
Chapters: 54 | Story / art: Kkomabi | Platform: WEBTOON (English edition posted January 2024) | Status: Completed (2010 to 2011)
It opens with a district attorney tied to a crucifix, held by a serial killer named Tang Lee, and then follows Tang's descent from average nobody to murderer. The catch is that every one of his victims turns out to be a criminal who escaped justice. Where Vigilante is about choosing violence, A Killer Paradox is about stumbling into it and being chased for it. Netflix released the live-action series on February 9, 2024.
COPYCAT cover art.
6. COPYCAT (new in 2026)
Latest English episode: Episode 30, October 27, 2026 | Story / art: Carnby Kim / Youngchan Hwang | Platform: WEBTOON, weekly (listed under Wednesday; 11 newer episodes in the app) | Status: Ongoing
The newest series on this list. A serial killer is staging corpses as "self-destruction art" and selling them to the ultra-wealthy, and failed artist Suchan Kim recognizes the concept as his own, stolen from an exhibition nobody took seriously. His need to prove it turns into something darker. The Korean run began in January 2026 and the English edition started with a Prologue on April 14, 2026. It is ongoing, so the ending is still unwritten. COPYCAT review → | COPYCAT reading guide →
Money Game cover art.
7. Money Game (The 8 Show)
Chapters: 60 | Story / art: Bae Jin-soo | Platform: WEBTOON (app; free access varies) | Status: Completed (2018 to 2020)
Eight participants, 100 days, and a shared pot of 44.8 billion won. Locked in a specially built TV set with a set of clothes and a rule book, they pay 1,000 times the normal price for everything they buy, and every purchase cuts into what they can walk away with. The tension comes from the rule book: everyone has a reason to spend as little as possible, and everyone can see who is breaking ranks. Netflix's The 8 Show (May 2024) is based on Money Game and Bae Jin-soo's Pie Game.
All of Us Are Dead cover art.
8. All of Us Are Dead
Chapters: 130 | Story / art: Joo Dong-geun | Platform: WEBTOON (app; free access varies) | Status: Completed (2009 to 2011)
Students at Hyosan High School realize their school is ground zero for a virus that turns people into flesh-eating monsters, and they are trapped inside with their infected friends and teachers. It is the older, rawer cousin of Sweet Home: the same closed-building pressure, with a classroom instead of an apartment block. Netflix adapted it in January 2022.
Dice: The Cube That Changes Everything cover art.
9. Dice: The Cube That Changes Everything
Episodes: 388 | Platform: WEBTOON (app; free access varies) | Status: Completed (2013 to 2021)
Dongtae is at the bottom at school in looks, grades and social life until a popular transfer student offers him a way to change all of that. What starts as a wish-fulfillment setup turns into a long serialization about what happens when power is handed out unequally to people who didn't sign up for a game. The thriller element is social: the gap between Dicers and everyone else keeps getting more dangerous. It ran for eight years and finished at 388 episodes.
Killing Stalking cover art.
10. Killing Stalking
Chapters: 71 | Story / art: Koogi | Platform: Lezhin (English) | Status: Completed (2016 to 2019) | Content warning: Adult content, graphic violence, depiction of abuse
Yoon Bum breaks into the home of his obsession, Oh Sangwoo, and finds something that traps him there. AniList marks the title as finished and adult, and the series includes graphic depictions of abuse and violence. It does not endorse its subject matter, but it does not soften it either. Read with awareness of what it contains; it is not for the same reader who starts with Sweet Home.
