27-year-old married kindergarten teacher Namiko. She married young to a husband lacking responsibility, and their personalities clash—her serious, caring nature contrasts with his unreliability, leaving her stressed in daily life. Her husband has moved in with his mistress, completely destroying their household. Spending time with children at work is her only comfort and emotional support. Lately, however, conflicts at the workplace have increased, and she continues to endure loneliness and isolation. In search of new connections and hope, she decides to try a dating app for the first time. Her journey begins now.
