When Killing Stalking Chapter 1 was first released, it generated immediate and intense reactions. The series won the ₩100,000,000 Grand Prize Award at the Second Lezhin World Comics Contest, validating Koogi’s bold vision. However, the controversy surrounding the webcomic has been equally significant.

Killing Stalking chapter 1 immediately establishes a dark, psychological horror atmosphere by subverting the expectations of a typical stalker story.

This post contains spoilers for Chapter 1 and discusses themes of violence and abuse. Reader discretion is advised.

The chapter concludes on a cliffhanger that sets the stage for the entire series. Sangwoo returns home unexpectedly. Discovering Bum in his basement, Sangwoo violently incapacitates him—breaking his legs to prevent escape—and takes him captive. Rather than the romantic reunion Bum had fantasized about, he finds himself trapped in a nightmare of abuse, manipulation, and forced dependency.

Ethan had always been good at blending in. He could slip through crowds like a ghost, his presence unnoticed until it was too late. Tonight, however, he wasn’t looking for anonymity—he was hunting.

The first chapter is a perfect short story in isolation: A boy breaks into a house, and the monster welcomes him home. It is a masterpiece of dramatic irony—the reader knows Bum is doomed within the first five pages, but we watch him walk into the basement anyway.

The most terrifying aspect of the first chapter is not the violence (which hasn’t yet occurred) but Bum’s desperate, all-consuming isolation. His internal monologue reveals a person who has romanticized his own delusions to the point where breaking into someone’s home feels like an act of love.

Bum, terrified, stutters an apology. He expects rage. He expects disgust. But Sangwoo smiles. He is calm, polite, and eerily welcoming. He offers Bum tea. He listens to Bum’s confession of love. For three horrifying pages, the reader thinks, "Is he forgiving him? Is this the start of a twisted romance?"
