Chapter 1 - Killing Stalking

The first chapter of the psychological horror manhwa Killing Stalking by Koogi introduces

Before the first chapter even begins, Koogi establishes the foundations of Yoon Bum's character. Bum is a scrawny, socially withdrawn young man with a devastating history of abuse and neglect. Orphaned at a young age, he was raised—if that word can be used—by an uncle who subjected him to prolonged sexual and physical abuse. This trauma left deep psychological scars, contributing to what is later identified as Borderline Personality Disorder, along with severe anxiety and depression.

What he finds breaks the illusion completely. Bound, bloodied, and weeping on the basement floor is a severely tortured woman. Before Bum can fully process this horrific discovery, a shadow looms behind him. Sangwoo appears, his charming facade completely shattered, holding a golf club. With a sinister smile and a brutal strike, Sangwoo knocks Bum unconscious, ending the chapter on a chilling cliffhanger. Key Character Introductions killing stalking chapter 1

The chapter ruthlessly deconstructs the common trope of the “persistent admirer.” Bum’s feelings are not romantic; they are pathological. The story forces the reader to confront the terrifying reality of obsession: it is not about love, but about possession and control, and it often leads the obsessed into grave danger.

The central twist of the chapter is the complete reversal of the stalker/stalked dynamic. Bum believes he holds power through secret knowledge and surveillance. In one scene, he is reduced to a helpless witness, and finally, to discovered prey. The “hunter” becomes the “hunted.”

Bum’s motivation for entering the house is rooted in a desperate, pathological need for connection. He is looking for "love" in the most invasive way possible. Chapter 1 posits that Bum’s vulnerability—his lack of a support system and his fragile mental state—is exactly what makes him the perfect victim for someone like Sangwoo. It sets the stage for a toxic cycle of codependency that defines the rest of the series. The first chapter of the psychological horror manhwa

Bum tries to explain, tries to stammer out some excuse, but Sangwoo isn't listening. The first swing connects with Bum's side, sending him crashing to the floor. The next swing—a sickening crunch—shatters his ankle. Bum screams, but the sound is lost in the enclosed space. Sangwoo swings again, breaking the other ankle.

The story introduces us to Yoon Bum, a protagonist who is profoundly unlikable yet pitiably desperate. Bum is not a hero. He is a traumatized young man suffering from severe mental illness, stemming from a lifetime of abuse and neglect.

Before Bum can process the horror or attempt to escape, Sangwoo appears behind him. The chapter closes with a chilling, violent cliffhanger as Sangwoo strikes Bum down, welcoming him to his true home.

He doesn't kill Bum. Instead, he lowers the bat, crouches down, and tilts Bum's chin up to look him in the eye. Then, in a move that feels almost tender if you ignore the context, he kisses him.

"You weren't supposed to see that," Sangwoo says quietly. Then, the final line of the chapter, delivered with a sigh: "I guess you have to stay here forever now."

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.
