The primary genius of Killing Stalking Chapter 1 is its Trojan Horse structure. Koogi deliberately draws the first half like a typical Yaoi or Shoujo romance. The paneling, the screen tones, the sparkles in Bum’s eyes—it all mimics the language of love. When the violence hits, it doesn't just scare the character; it violates the reader's trust in the medium itself.
Overview
Chapter 1 of Killing Stalking, the acclaimed and controversial Korean webtoon by Koogi (serialized on Lezhin Comics), serves as a masterclass in atmospheric horror and psychological tension. Within its first few pages, it dismantles any expectation of a standard romance or thriller, instead establishing a deeply unsettling foundation for the story’s central, toxic dynamic.
The chapter primarily follows Yoon Bum, a young man suffering from severe social anxiety, obsessive-compulsive disorder, and a fixation on his former high school classmate, Oh Sangwoo. Bum’s narrative is presented through an intimate, often claustrophobic first-person lens, immersing the reader in his warped perceptions and desperate loneliness.
Plot Summary
The chapter opens with Bum breaking into a house. Through his internal monologue and scattered flashbacks, we learn he has been obsessively stalking Sangwoo for months. He has memorized Sangwoo’s daily routine, copied his apartment keys, and secretly entered his home multiple times, finding comfort in touching his belongings.
The specific incident in Chapter 1 is triggered by Bum’s mistaken belief that Sangwoo is planning to move away. Panicked at the thought of losing his “prey,” Bum decides to act. He breaks into Sangwoo’s house one last time, intending to “say goodbye.” He lies down on Sangwoo’s bed, hugging a pillow and inhaling the scent, revealing the extent of his fetishistic obsession.
The narrative’s horror pivots when Bum hears the front door unlock. He panics and hides in a closet. From his dark hiding spot, he watches Sangwoo enter, seemingly normal. However, Sangwoo is not alone. He is dragging the unconscious body of a woman—a clear victim. The mundane tableau of Sangwoo’s living room transforms as he calmly prepares tools, ties the woman to a bed, and proceeds to brutally murder her.
Bum, frozen in terror, witnesses the entire scene: the violence, the dismemberment, and Sangwoo’s chillingly composed demeanor afterward. When Sangwoo approaches the closet to dispose of bloodied sheets, Bum’s phone rings, exposing his hiding place. The chapter ends on a cliffhanger with Sangwoo slowly opening the closet door, a neutral yet terrifying expression on his face, trapping Bum in the ultimate predator-prey reversal.

The Beginning of a Nightmare: Diving into Killing Stalking Chapter 1
If you’ve spent any time in the darker corners of the psychological thriller manga world, you’ve likely heard the name Killing Stalking. Koogi’s manhwa became a viral sensation, not for being a sweet romance, but for its visceral, unsettling exploration of obsession and trauma.
Chapter 1 serves as a masterclass in the "bait and switch." It sets up a premise that feels like a standard (albeit creepy) stalker story, only to pull the rug out from under the reader in its final moments. The Protagonist: Yoon Bum’s Twisted Devotion The primary genius of Killing Stalking Chapter 1
The story introduces us to Yoon Bum, a thin, sickly, and social outcast. We quickly learn that he is obsessed with Oh Sangwoo, a peer from his time in the military who is now a popular, handsome college student.
Bum’s "love" isn't healthy. He follows Sangwoo, watches him from afar, and eventually manages to crack the passcode to Sangwoo's front door. For the first half of the chapter, the reader feels a sense of secondhand dread for Sangwoo. We think we are watching a story about a fragile boy stalking an innocent, "golden boy" victim. Crossing the Threshold
When Bum finally enters Sangwoo’s home, the atmosphere shifts. The clean, modern interior of the house contrasts with Bum’s frantic, sweaty desperation. He explores the space like it’s a temple, searching for scraps of Sangwoo’s life.
However, the silence of the house is eventually broken by a noise from the basement. This is where Killing Stalking defines itself. Bum, driven by curiosity, descends into the dark, expecting perhaps to find more of Sangwoo’s secrets. The Twist: Who is the Real Monster?
What Bum finds in the basement is a woman, bound and brutally injured. Before he can even process the horror, Sangwoo appears behind him.
In a single moment, the power dynamic of the entire series flips. The "victim" (Sangwoo) is revealed to be a cold-blooded serial killer, and the "predator" (Bum) is suddenly the prey. The chapter ends with a sickening blow, leaving Bum—and the reader—trapped in a basement that they'll spend the rest of the series trying to escape. Why Chapter 1 Works
Killing Stalking Chapter 1 is effective because it plays on our assumptions. It uses the "stalker" trope to distract us from the much larger threat. It establishes the central theme of the series: that in a world of monsters, there is no such thing as a hero—only different degrees of brokenness.
If you’re looking for a light read, turn back now. But if you want a psychological thriller that will haunt you long after you close the tab, Chapter 1 is the perfect, terrifying doorway.
Warning: The story contains mature themes, violence, and potential triggers. Reader discretion is advised.
Killing Stalking is a popular South Korean webtoon series written by Yuri and illustrated by Suzi.

Would you like to know more about the series or is there something specific you'd like to discuss about Killing Stalking?
| Question | Possible Interpretation | |----------|------------------------| | Why doesn’t Sangwoo kill Bum immediately? | He enjoys control more than killing. Bum’s obsession amuses him. | | Is Bum a reliable narrator? | No—he romanticizes Sangwoo even after being attacked. | | Does the story warn against stalking? | Yes, by showing the worst-case outcome. | | Is there any consensual relationship? | No. Chapter 1 makes captivity unambiguous. |
This is the moment the internet went silent.
The two enter Sangwoo’s home. It is an affluent, clean, modern two-story house. Bum is mesmerized. He compliments the interior. Sangwoo disappears into the kitchen to grab drinks.
Then—click.
Bum hears the sound of a deadbolt sliding into place. He turns around. Sangwoo is standing there, not holding drinks, but holding his keys. He isn't drunk anymore. His eyes are clear, cold, and predatory. The soft, inviting smile is gone, replaced by the flat affect of a sociopath calculating the next ten moves.
Sangwoo simply says, "The doors are locked."
The plot of Chapter 1 kicks into gear when Bum follows Sangwoo home one rainy night. He watches from the shadows as Sangwoo fumbles with his keys. Sangwoo appears intoxicated, stumbling and leaning against his front gate.
In a moment that defines Bum’s tragic flaw—reckless, desperate hope—Bum approaches him. He calls out, "Sangwoo-ssi?" and asks if he is okay.
Sangwoo looks up. He smiles. He remembers Bum’s name.
To a normal person, this is a red flag. To Yoon Bum, this is the climax of a fantasy years in the making.
Sangwoo invites him in for a drink. "I don't want to be alone tonight," he says, his voice soft and inviting. Bum’s internal monologue explodes with joy: "He wants me! He finally recognizes me!"
The reader is lulled. The art becomes warmer. The rain outside creates a cozy atmosphere. For three glorious panels, Killing Stalking pretends to be a romance.
