This is the beginning of one married woman’s journey to find herself in a world beyond love and romance. Thirty-year-old Yukine Nakasaki lies to her husband for the first time and travels to the shoot. Standing at sunset on the beach where he once proposed, she recalls their memories with a conflicted expression. Torn between guilt and desire, she plunges into a sweeping first-affair story in a 190-minute, two-day documentary of her first porn shoot.
