This is the beginning of a married woman's journey to find herself in a world that is neither love nor love. Yukine Nagasaki, a 30-year-old married woman who lied to her husband for the first time and came to the shooting location. ``I was proposed to here while looking at the ocean, and we got married.'' She had a complicated expression on her face as the setting sun lit up the beach, filled with memories of her husband. A story of a ``first affair'' as grand as the blue sea. A 190-minute documentary about her two days and one night in which she drowns in the turbulent waves of infidelity while shaking with guilt and desire for her husband.
