Manhwa Like Bastard: 7 Picks Sorted by What It Does

"Manhwa like Bastard" is a specific request that most recommendation lists handle badly. They index on the genre label (psychological thriller) and return results that share the category but not the mechanism. Bastard's specific quality isn't thriller plotting. It's the architecture of knowing. Jin Seon knows his father kills people. The reader knows. His father knows Jin knows. The story runs on what that knowledge costs everyone in the room, and what happens when a third party enters who doesn't know yet.

That's a precise set of structural conditions. Series that replicate even two of them are worth reading. Series that replicate all three are rare.

This list of manhwa like Bastard is sorted by which element each series delivers most directly: the psychological cat-and-mouse, the complicity and silence, the realistic horror without supernatural scaffolding, or the tight pacing of a completed story that doesn't overstay.

TL;DR: Manhwa like Bastard: 7 series sorted by psychological cat-and-mouse tension, moral complicity, and realistic horror. All completed or worth the wait.

Overview

Bastard is a psychological thriller manhwa written by Kim Carnby and illustrated by Hwang Young-chan, published on Lezhin Comics and later made fully available on WEBTOON. It runs 92 chapters and is completely finished, with no sequel and no ongoing continuation. The same creative team went on to write Sweet Home.

The premise is compact and brutal. Jin Seon is a high school student who knows his father is a serial killer. He has known for years. His father uses Jin's social connections to select victims, and Jin's silence makes him complicit. The story opens when a new girl, Yoon Kyun, enrolls at school and the father identifies her as his next target.

What distinguishes Bastard from other thriller manhwa is the specific mechanism of its dread. There are no supernatural elements, no power systems, no external threat that can be defeated. The source of horror is a family relationship, and the proximity to danger that comes with it. The series runs entirely on information asymmetry: who knows what, who is choosing not to say it, and what that silence costs each person in the room.

The series is not horror in the monster or gore sense. The violence, when it appears, is often implied rather than shown. The weight comes from psychological architecture: readers know the danger, characters are discovering it at different speeds, and the story exploits that gap without releasing the pressure.

Readers searching for manhwa like Bastard are usually looking for one of three things: the cat-and-mouse tension, the realistic-horror-without-supernatural-scaffolding, or the tight pacing of a story that ends when it means to. This list is sorted by which of those elements each pick most directly delivers.

Sweet Home: The Same Dread, Bigger Stage

Sweet Home.

The logical starting point for manhwa like Bastard, because it's the same people. Kim Carnby wrote it, Hwang Young-chan drew it. If Bastard is a chamber piece (small cast, one location, pressure building from silence), Sweet Home is what happens when the same creative team decides to scale up.

The premise is structurally different. Bastard's horror is knowing the killer is in the apartment with you. Sweet Home's horror is that the building has become a kind of trap for an ensemble of survivors, and the threat is transformation: people with overwhelmingly strong desires begin to turn into monsters shaped by those desires. It's supernatural where Bastard is not.

What carries over is the craft. Carnby builds dread through proximity and information asymmetry. You know things the characters don't. Characters know things you wish they'd say aloud. The camera (if you can call panel composition that) favors faces over action. By chapter 20 of Sweet Home, the tone feels familiar if you've read Bastard. The same management of silence. The same sense that what people don't say is doing more work than what they do.

At 140 chapters and complete on WEBTOON, it delivers a full arc. The Netflix adaptation (three seasons, 2020-2024) exists and is fine. The manhwa's ending is more contained and doesn't require the show's structural revisions to land.

The Box: Cat-and-Mouse Without Rescue

The Box (Taehyung Kim) is the closest structural match to Bastard's specific cat-and-mouse architecture. The protagonist is not a killer but has intimate knowledge of one. The story runs on that asymmetry: what you know about someone, and whether that knowledge protects you or just makes the danger more visible.

The pacing is tight in a way that earns comparison to Bastard's chapter-to-chapter compression. Bastard rarely wastes a chapter. It doesn't run recaps or filler. The Box applies the same discipline. By chapter 15, the reader has enough information to be afraid, and the series spends its remaining chapters making that fear work precisely rather than escalating it gratuitously.

At 87 chapters and complete, The Box fits in a weekend reading session. The ending lands on a note that explains why the opening chapter was structured the way it was, one of those completions that rewards rereading from the start.

If Bastard is about what complicity costs, The Box is about what knowledge costs. They're related questions with differently structured answers.

Weak Hero: Realistic Stakes, Moral Complexity

Weak Hero.

Weak Hero (SeoPass / Razen) is not a psychological thriller by genre. It's a school action manhwa. But it earns a place on a list of manhwa like Bastard because it shares the quality that makes Bastard work: no clean hands.

The premise: Gray Yeon, a studious student, starts fighting back against school bullies using calculated violence and a willingness to hurt people badly enough that they remember it. The series never lets the reader fully root for him without complication. He's effective. He's also doing harm to achieve that effectiveness. The question of whether his methods are defensible (or whether "defensible" is the wrong frame entirely) runs through the whole series.

There are no powers. The violence is realistic and has realistic consequences. Broken bones don't heal in three chapters, reputation damage compounds, the school ecosystem responds to Gray's presence in ways that aren't cleanly good or bad. Bastard's Jin Seon is complicit through silence. Weak Hero's Gray Yeon is complicit through action. Different mechanism, same moral discomfort.

Ongoing at 280+ chapters. The first 80 chapters are the strongest section. The series introduces a second protagonist around chapter 40 that gives it more structural complexity.

Killing Stalking: Dread from Inside the Relationship

A content note first: Killing Stalking (Koogi) depicts psychological captivity, a Stockholm Syndrome dynamic, physical abuse, and non-consensual scenarios throughout its 67-chapter run. It's rated 18+ on Lezhin. Readers who find abusive relationships romanticized in fiction (they aren't here, but the subject matter is present) should be aware of what they're reading before starting.

With that said: Killing Stalking belongs on a list of manhwa like Bastard because it operates on a precisely adjacent set of conditions. The protagonist, Yoon Bum, has been stalking Sangwoo. When he breaks into Sangwoo's house, he discovers that Sangwoo kills people. He is now a prisoner of someone he knows is a killer, who knows Yoon Bum was stalking him, and who is using that knowledge as leverage.

That's a version of Bastard's central dynamic (trapped in proximity to a killer, where escape is complicated by what the killer knows about you) pushed to its most extreme formal expression. The dread in both series comes from the same place: the horror is interpersonal, not atmospheric. It's specific. It has a name and a face.

At 67 chapters and complete on Lezhin, it's the shortest completed recommendation on this list. Approach it as a psychological study, not as a thriller with a rescue at the end.

Vigilante: Complicity Wearing the Shape of Justice

Vigilante (Kim Sae-am / Jinwan) is a superhero adjacent series where the protagonist, Jiyong, is secretly conducting vigilante executions of criminals the legal system failed to convict. His day identity is a police academy student. The story's dramatic irony (that he's training to be law enforcement while operating outside it) is maintained with more structural care than most dual-identity narratives manage.

The connection to Bastard: Jiyong is not morally clean, and the series refuses to let him be. His targets are unambiguously guilty. His methods are not legally or ethically sanctioned. The series keeps both facts in frame at the same time rather than resolving them into simple vigilante-hero logic. By chapter 35, the question isn't whether Jiyong is doing the right thing. It's whether "right" is still a coherent concept in the frame the series has built.

At 65 chapters and complete, it's tighter than most superhero-adjacent series. The ending doesn't flinch from its implications.

Shotgun Boy: Kim Carnby's Other Completed Series

If Sweet Home is Kim Carnby at scale and Bastard is Carnby at his most compressed, Shotgun Boy (also released as Pigpen in some translations) is somewhere in between. The setup: a bullied student named Gyuhwan survives a monster attack at a rural school because he happens to have access to a shotgun.

The rural isolation gives it a different texture than Bastard's urban apartment claustrophobia. Open space doesn't register as safer. The monsters in Shotgun Boy exist, unlike in Bastard, but Carnby's treatment of them follows the same logic he applied to Sweet Home: the horror isn't the monster. It's what the monster occasions in the humans nearby. Who people become when survival is the only imperative, and what that says about who they already were.

Completed at 69 chapters on WEBTOON, free. Start it after Bastard and Sweet Home; it reads differently once you recognize Carnby's recurring thesis.

Cheese in the Trap: Sustained Ambiguity as Horror

Cheese in the Trap.

Cheese in the Trap (Soonkki) is technically a college romance. It also contains the most carefully constructed sustained ambiguity in any manhwa on this list about whether the person you're closest to is dangerous.

Yoo Jung is a senior who is helpful, charming, and occasionally acts in ways that are difficult to explain without assuming he's manipulative. His girlfriend, Seol, is an intelligent narrator. The series spends 230+ chapters refusing to confirm whether her readings of him are accurate. He's never caught. He's never exonerated. The narrative maintains both possibilities as live options for the full run.

Bastard resolves the question of who the dangerous person is on page one. Jin's father is a killer. That's not a twist, it's the premise. Cheese in the Trap's long game is to keep that question open. Different architecture, same psychological mechanism: the dread is relational, it comes from knowing someone well and still not knowing what they're capable of.

Completed at 301 chapters. WEBTOON. The series is significantly longer than the others on this list, but the pacing is better than the chapter count implies. Soonkki doesn't run filler.

A Note on Death Note

Death Note is manga (Japanese), not manhwa (Korean), so it doesn't fit the list proper. But the comparison to Bastard comes up often enough to address directly.

The structural similarity is real: both series put the reader in intimate proximity to someone who kills people and asks what that proximity costs. The difference is orientation. Light Yagami in Death Note has the god-perspective. He is the killer, he has power, the plot is about whether anyone can stop him. Jin Seon in Bastard is the inverse: he has no power, he is a witness and a shield, and the plot is about what that position does to a person over time.

Death Note is a wish-fulfillment story with ethics as its antagonist. Bastard is a survival story where the most threatening person in the room is someone Jin Seon should be able to trust. Both are worth reading. They're answering different questions.

For readers who finished Death Note and want the same intellectual engagement with killing as a psychology subject, Bastard is the better follow-up than most manhwa recommendations in this genre. It just won't give you the catharsis of watching a genius versus another genius. That's a trade.

Reading Order Recommendations

Start with Bastard if you haven't read it. At 92 chapters and free on WEBTOON, it's a one-session commitment. Read it before anything on this list, including Sweet Home, because Sweet Home lands differently once you have Bastard's emotional logic in place.

After that:

• If you want the same creative team's next project: Sweet Home immediately, then Shotgun Boy
• If you want the cat-and-mouse tightest analog: The Box
• If you want the moral ambiguity without resolution: Cheese in the Trap (long-haul investment)
• If you want realistic violence and a protagonist who isn't clean: Weak Hero (completed, 268 chapters, WEBTOON)
• If you want the extreme formal limit of the proximity-to-killer structure: Killing Stalking (read the content note)
• If you want completed arcs under 100 chapters: Vigilante, The Box, Shotgun Boy

Bastard's 92 chapters take about five to six hours to read at a moderate pace. The chapter structure is unusually tight. Kim Carnby doesn't let panels breathe when the tension is building. By chapter 40, the series has established its stakes clearly enough that the final arc earns its complexity rather than arriving at it unexpectedly.

Frequently Asked Questions

Is Bastard a horror manhwa or a psychological thriller? Psychological thriller. The horror in Bastard comes from knowing who the monster is from chapter one. Jin Seon's father is a serial killer, and Jin knows it. The dread is entirely human and relational, not supernatural. There are no monsters, no powers, no genre mechanics. The tension is built from complicity, silence, and proximity to someone capable of violence. If you're coming from Sweet Home expecting body horror, Bastard works differently.

Is Bastard by the same author as Sweet Home? Yes. Bastard is written by Kim Carnby and drawn by Hwang Young-chan, the same creative team behind Sweet Home. Bastard was their first major WEBTOON collaboration and predates Sweet Home by about two years. The thematic territory overlaps: both series ask what it costs to be near someone who causes harm. Bastard runs 92 chapters to Sweet Home's 141.

Is Bastard completed? Yes. Bastard is fully completed at 92 chapters on WEBTOON. The entire run is free to read. There is no sequel series and no continuation. Kim Carnby moved on to Sweet Home and later Shotgun Boy after Bastard concluded.

Is Bastard appropriate for younger readers? No. Bastard deals with serial murder, psychological complicity, and scenes of violence and abduction. The content is not gratuitous in the way some mature manhwa is, but it is consistently dark and assumes adult tolerance for morally uncomfortable subject matter. WEBTOON's recommended age for the series is 16+, but the psychological weight skews toward adult readers.

How does Bastard compare to Death Note? The comparison holds structurally but not in tone. Death Note is about a protagonist who becomes the killer. Light Yagami acquires power and uses it. Bastard is about a protagonist adjacent to a killer who has no power and must decide whether to use what small leverage he has. Death Note is a god-mode fantasy with ethics as its antagonist. Bastard is a survival story where the most threatening person in the room is someone who loves you, conditionally.

Where can I read Bastard in English? Bastard is available in full on WEBTOON in English, free. Seven Seas Entertainment also released a print edition collected in three omnibus volumes, if you prefer physical. The WEBTOON version is the easiest access point. The series is complete, so there's no wait between chapters.

Is there a sequel to Bastard or more work by Kim Carnby? No direct sequel. Kim Carnby wrote Sweet Home next (with the same artist), a survival horror series in a different register: bigger cast, monster transformations, ensemble stakes. After Sweet Home, Carnby wrote Shotgun Boy, a rural survival horror series. Readers who want more of Bastard's claustrophobia will find Shotgun Boy closer in tone than Sweet Home.
