Due to her husband quitting his job, Kana started working as an employee at another company. Buried in daily tasks and constant overtime, her husband is always exhausted. Yet no one offers him words of comfort or encouragement. The only person who truly supports him emotionally is security guard Ozawa. When her husband collapses from overwork, Ozawa not only takes care of him but even nurses him back to health—his kindness becomes a profound source of strength for Kana. Meanwhile, her husband only directs anger at her for coming home late. Feeling deeply lonely, Kana finally breaks down and pleads with Ozawa to hold her just once. In that moment, his warmth completely envelops her.
