Koogi’s art style in Chapter 1 uses a muted, gritty color palette dominated by sickly greens, dull grays, and deep shadows. The character expressions are hyper-exaggerated during moments of terror, capturing the raw, visceral panic of the situation. The pacing relies heavily on tight framing, making the reader feel trapped alongside Bum inside the dark hallways. Conclusion: A Masterful First Hook
The story opens from the perspective of Yoon Bum, an emaciated, socially isolated young man who harbors a severe, consuming obsession with Oh Sangwoo. Sangwoo is his former military peer—handsome, charismatic, and universally beloved. Bum’s infatuation is not passive; it is a desperate, pathological fixation. He spends his days tracking Sangwoo’s digital footprint and lurking around his neighborhood.
One of the most significant aspects of Chapter 1 is its exploration of San-young's inner monologue. As he watches Soo-jin from afar, his thoughts reveal a disturbing level of fixation and possessiveness. He fantasizes about Soo-jin, imagining her as his girlfriend and ruminating on the idea of "being with her." These thoughts are juxtaposed with Soo-jin's own words and actions, which serve to unintentionally encourage San-young's behavior.
While the dusting "feature" was intended to grant him access to his crush, it serves as the inciting incident for the psychological horror to follow, as it reveals Sangwoo’s true nature as a serial killer.
If you were in the anime/manga/manhwa community between 2016 and 2019, you heard the name Killing Stalking . Often mislabeled as a "Yaoi" romance, Koogi’s psychological horror masterpiece actually opens the door with a very different, much more terrifying key.
There, Bum discovers a heavily bruised, bound, and gagged woman crying for help on the floor.
The characters in Chapter 1 are multifaceted, with distinct personalities and motivations. Chan-woo's character, in particular, is intriguing, as his obsession with Sang-yeon is depicted as both disturbing and pitiful. Sang-yeon, on the other hand, is portrayed as enigmatic and charismatic, making him an object of fascination for Chan-woo and, by extension, the readers.
