One day, Oshio found himself having sex on a rocky beach with a man he met at a party without realizing it. It was as if the party itself was a dream. He found himself surrounded by men in camouflage uniforms, SM, cross-dressing, orgies.... So many things came at him one after another... He woke up from the dream, but it was still a dream. It's like a dream that never ends. Is this a nightmare?
