Zhou Guobin's long-awaited trip to Tokyo was just to meet netizen Momo Nogi, who he had been in love with for three years. Suddenly, a mysterious man stuffed Bin with a small book called "Shi" and a condom, threatening him to look for his pubic hair, otherwise he would be exhausted and die! This book "Shi" allowed Bin to meet different AV actresses one after another.
