Miyuki Kikuchi works as a secretary in the protagonist’s office, presenting herself as a quiet, intellectually driven figure. Her past harbors an unrequited crush on Makoto, her high school tutor, whose obliviousness to her timid advances—misread as intimidating glares—deepened his anxieties around women.

Professionally composed, her personal life simmers with contradictions. She publicly scorns romance, declaring herself contentedly single, yet privately aches for motherhood through natural conception. This tension pits societal pressures against her suppressed aspirations. Lingering affection for Makoto further undermines her resolve to avoid emotional entanglements.

Her interactions reveal layered social dynamics. Arisa, a flirtatious lesbian colleague, chips at Miyuki’s aloofness with persistent banter, forging an irritable yet genuine camaraderie. Similarly, she bonds with Misaki Manaka, a coworker who once rivaled her for Makoto’s attention, bridging initial friction into mutual respect.

Miyuki’s evolution unfolds through reluctant introspection. Her journey weaves between guarded composure and simmering desires—nostalgia for Makoto, maternal longing—exposing vulnerabilities beneath her analytical exterior. Each choice reflects the push-pull of emotional self-preservation against the ache for connection.
