The episode opens in 1945 Gyeongseong, under Japanese occupation. The city, a mix of modern influences and traditional Korean culture, is depicted in all its complexity—bustling markets, shadowy alleyways, and the looming presence of Japanese authority. Amidst this backdrop, whispers of strange disappearances begin to spread among the locals, creating an undercurrent of fear and unease.

We are introduced to Jang Tae-sang, a charming and influential figure who runs a pawnshop in the city. Tae-sang, though outwardly carefree and well-connected, has a troubled past that has made him wary and deeply perceptive. His character is immediately established as someone who is not afraid to bend the rules to protect those he cares about.

The narrative quickly shifts to Yoon Chae-ok, a strong-willed and resourceful woman searching for her mother, who disappeared under mysterious circumstances. Chae-ok is depicted as a character with a deep sense of determination and a willingness to confront danger head-on. Her journey leads her to cross paths with Tae-sang when she seeks his help in navigating the darker, more dangerous parts of the city.

As Tae-sang and Chae-ok begin to investigate, they uncover unsettling clues that suggest something inhuman is responsible for the disappearances. Their initial inquiries are met with resistance and fear from the locals, who seem to know more than they are willing to admit. The tension escalates when they encounter their first direct sign of the creature—a mutilated body left in a state of horror.

The episode crescendos in a nerve-wracking sequence where Tae-sang and Chae-ok find themselves trapped in an abandoned warehouse at night. The sound design and cinematography create an intense atmosphere as they hear the creature’s movements around them, but never get a clear view of it. The episode ends on a cliffhanger, with the duo narrowly escaping the warehouse as they realize they are dealing with something far more dangerous than they initially thought.

Themes and Atmosphere:

Episode 1 expertly blends elements of horror, suspense, and historical drama. The oppressive atmosphere of Japanese-occupied Gyeongseong adds a layer of tension to the unfolding mystery, making the characters’ fight against the supernatural feel even more perilous. The episode also touches on themes of survival and resistance, not only against the literal monster but also the figurative "monsters" of oppression and fear.

The visual and auditory design of the episode heightens the sense of dread, with shadowy, dimly lit scenes and eerie sound effects that keep the viewer on edge. The creature, though barely seen, is a menacing presence that promises to become a central figure of terror as the series progresses.
