Two coworkers at the same airport meet at their parent company's cafeteria. Sitting in the same seats every day and ordering the same meals, they gradually grow closer. Her name is Mayumi, and she's been married for three years. Her relationship with her husband, which initially seemed stable, slowly develops cracks due to their irregular shift schedules. As a maintenance technician, he works early mornings and late nights, leaving her feeling lonely and emotionally disconnected. Despite being married, her daily life consists only of commuting between Nishikamata and Haneda, no different from her single days. Even when they share a bed, her husband wears earplugs and a blindfold, fully guarded—making her feel too defeated to initiate intimacy. Though she still loves him, her unmet desires create an unbearable dilemma. Tonight, she craves excitement. These small moments of connection might become the start of something new.
