This is the beginning of a journey where one married woman searches for herself in a world that is neither love nor romance. Yukine Nakazaki, 30, is a married woman who came to the shooting location for the first time, lying to her husband. “He proposed to me here while looking at the ocean, and we got married.” She had a complicated expression on her face as she was illuminated by the setting sun on the beach filled with memories of her husband. A story of a “first affair” as grand as the blue sea. A 190-minute documentary of a two-day, one-night first shoot in which she drowns in the rough waves of infidelity, torn between guilt and desire towards her husband.
