Yoko Nagawa, a brown-haired young woman with striking blue eyes, shares a longstanding bond with Makabe Hiroshi, her childhood friend. Her family’s ties to the apartment complex owned by Hiroshi’s parents draw her into his new life there—a place chosen for its affordability despite whispers of a spectral presence. Proximity to the building intertwines her with both Hiroshi’s routines and the eerie occurrences rumored within its walls.

After Hiroshi’s relocation, her older brother Kotobuki engages with him while organizing an event, subtly exposing undercurrents of friction or secrets tied to the apartment’s haunted reputation. The narrative weaves hints of unresolved history between the families and the ghostly lore, though Yoko’s direct stake in these mysteries remains an enigmatic thread in the broader tapestry of the unfolding story.
