Overview
Bastard is a psychological thriller built on a stomach-turning premise: the monster is your dad. Jin Seon is a quiet, withdrawn high-schooler, missing an eye and an arm, who flinches from everyone around him. The reason is his father, Dongsoo — handsome, charming, beloved by the community, and a serial killer. Worse, Jin has been forced into complicity, made to help his father pick out and lure his victims, living in constant terror that one wrong move means his own death. Then a bright, kind classmate named Kyun takes an interest in Jin — and catches Dongsoo's predatory eye as a potential target. Suddenly Jin has to decide whether to keep surviving by going along with it, or finally try to stop the man who owns his life. It's by writer Carnby Kim and artist Youngchan Hwang, the team behind Sweet Home, and it's free to read on WEBTOON.
What it does well
The tension is extraordinary. Bastard is a master class in dread — every interaction with Dongsoo is a knife's edge, every secret a potential death sentence, and the series wrings nearly unbearable suspense out of small moments: a glance, a lie, a phone left in the wrong place. It's the kind of thriller you read with your shoulders up around your ears.
Its perspective is what sets it apart. Telling a serial-killer story from the side of the killer's terrified, complicit child is a brilliant, uncomfortable choice. Jin isn't a hero — he's a victim who's done terrible things to survive — and the moral knot of his guilt, fear, and slow-growing courage gives the thriller real psychological weight beyond the scares.
And it looks fantastic. Youngchan Hwang's art is moody, polished, and brilliant at faces — the difference between Dongsoo's warm public smile and the dead-eyed predator underneath is genuinely chilling. The full-color visuals and clever paneling sell every beat of fear.
Where it falls short
It is grim, and relentlessly so. The abuse, violence, and dread are unbroken — there's almost no levity or relief, by design, which makes it powerful but also a heavy, sometimes punishing read. This is not a series for a bad day.
Some plot turns also ask you to accept characters making risky or convenient choices to keep the tension cranked, and a few late developments stretch plausibility in the way thrillers often do when the screws need tightening. These are minor dings against a very tightly built story, but the suspension-of-disbelief muscle gets a workout.
Verdict
Bastard is one of the best psychological thrillers in webtoons — a taut, disturbing, gorgeously drawn story that mines almost unbearable suspense from a brilliant, queasy premise. It's dark and heavy and not for everyone, but it's expertly crafted, genuinely scary, and, crucially, complete, so you can read the whole white-knuckle ride to its end. If you want a thriller that actually makes you sweat, this is essential.
