Nozomi Komine appears initially as a shy, uncharismatic high school classmate of Kimio Suga, yet her true nature proves mischievous and voyeuristic. Discovering Kimio hiding in the girls' locker room, she blackmails him into a daily ritual called "showing each other," where they mutually expose their bodies through their facing apartment windows. She frames this as an exploration of "true selves" without lies; it begins transactionally but evolves as her motivations deepen. She manipulates social dynamics among classmates, orchestrating interventions like resolving conflicts between Saya Hayakawa and Mahiru Shīna or exposing Mami Watarai's schemes against Mahiru. Demonstrating acute perceptiveness of hidden emotions, she engineers situations forcing honest reactions, such as locking herself with Kimio in a closet during a ski trip to provoke emotional intimacy, resulting in an almost-kiss. Her relationship with Kimio shifts significantly. Early interactions feature her teasing and control, unsettling him through the "showing" ritual. However, navigating conflicts—like fending off rivals Haruka Mukai or Michiru Sonoda—reveals genuine care. She poses as Kimio's girlfriend to deter Haruka, kissing him through a candy wrapper to sell the deception, blurring manipulation with authentic affection. Jealousy surfaces when Kimio attracts others, yet she consistently prioritizes his well-being during social or physical danger. Exhibitionism serves as her recurring tool for connection. The daily window ritual, initially exploitative, becomes a framework for mutual vulnerability, symbolizing her desire for unfiltered honesty. She pushes classmates toward similar transparency in their romantic entanglements. Her own emotional barriers lower through physical gestures like the closet near-kiss or later voluntarily kissing Kimio’s cheek, signaling a shift from detached observation to personal investment. She has black hair, blue eyes, and a November 1 birthday. Living directly across from Kimio’s apartment enables their rituals and facilitates collaborations, like coordinating to delete compromising photos during a school competition. Their story concludes with a return to the locker room, now marked by mutual understanding and resolved feelings.
