Sayaka Asai, a young widow, single-handedly operates Asai Cleaning, the laundry business she inherited after her husband Yuutarou's death six years prior. She barely scrapes by financially, sustained by loyal customers who frequent her establishment. Unbeknownst to Sayaka, these patrons are primarily retained through the efforts of her sole employee, Shinji Oura, who handles deliveries and daily operations.

Sayaka grapples with unresolved grief for Yuutarou and a growing physical longing, leaving her hesitant to pursue new romance. This internal conflict intensifies through an unexpected fixation on Shinji. His distinct body odor powerfully evokes memories of her husband, triggering secret fantasies and a profound yearning for intimacy. Her struggle pits honoring Yuutarou's memory against her own unmet needs.

Shinji's own attempts to express romantic feelings towards Sayaka complicate their employer-employee relationship. His interactions with other neighborhood women add further tension to Sayaka's emotional state. Her enduring widowhood shapes her cautious approach to relationships, defined by persistent grief and loneliness. These personal conflicts remain ongoing throughout her character portrayal.
