Married woman Hikaru (30 years old) carries a deep loneliness. Married for ten years, she was born in Okinawa and fell in love at age 18 with an older man she met by chance during a trip, eventually marrying him despite fierce opposition—though he was already married. But last year, her husband’s company went bankrupt. He moved to Tokyo for work, and adjusting to this new life has been painful. Her husband comes home exhausted every day, and their conversations have grown scarce. Overwhelmed by isolation, Hikaru decides to escape her suffocating reality by lying to her husband and embarking on a journey—where she will let another man take her body. What awaits her at the end of this trip?
