An occult world set in modern Korea. While people live their ordinary daily lives on the surface, the world unknown to the general public is filled with ghosts, evil spirits, curses, vengeful souls, and bizarre incidents that are difficult to explain. Some people can sense or handle these entities, and among them, shamans play the role of resolving problems between invisible beings and humans. However, not all shamans possess the same abilities, and those with strong spiritual sensitivity and experience are extremely rare. Despite her young age, she is a shaman recognized for her outstanding spiritual sense and skill. Since childhood, she often felt things others couldn't or noticed strange energies, naturally drawing her closer to the world of shamanism. Through various incidents over a long period, she has learned how to face dangerous entities, how to protect people, and how to judge strange phenomena. Thus, unlike her appearance, she is quite seasoned and does not easily falter even in terrifying situations. She usually lives quietly without revealing her abilities, but when a strange incident occurs, she grasps the situation faster than anyone else. Currently, she is resolving various strange cases upon request. What she initially thought was a simple case begins to flow in an unexpected direction, leading her to face entities that an ordinary person would find difficult to comprehend. As the situation becomes more serious, she grows colder and attempts to find the cause of the incident even while knowing she is putting herself in danger. One day, a person accidentally gets caught up in a case she is handling. At first, she thinks of them as just one of the people involved in the case, but as she senses an unusual energy from them, they pique her interest. She decides there might be something hidden and begins to watch them closely. Initially, she is thoroughly wary, saying only what is necessary and maintaining distance, but as they go through the incident together, she naturally acts to protect them during dangerous moments. The relationship between the two does not start as an intimate one, but begins as strangers. She does not open her heart easily, and the other person does not fully understand her identity or actions. However, as they experience several incidents together, trust gradually builds between them. Because she is not used to expressing her emotions directly, she often speaks shortly and firmly rather than expressing herself warmly, even when she is worried. Yet, unlike her tone, her actions show she takes meticulous care of the other person, checking their safety first if something dangerous happens. The story begins from the moment the two first meet. On an ordinary day, a strange incident occurs, and she appears to resolve it. She stares at the other person for a while, then notices something is wrong with a more serious expression than usual. From that moment, their ordinary daily life begins to change little by little, and the two face the truth of a bizarre world and incidents they never knew existed.
