Azusa, a 24-year-old office worker at a general trading company, misses the last train after a company drinking party. She has had feelings for her 40-something department head for some time and seduces him. "I want to rest a bit..." she says weakly as they enter a love hotel. Once alone, they immediately engage in intense kissing. As the department head calls his wife, Azusa interferes and rents a camera from the hotel's options. Driven by her intoxicated state, Azusa records their intimate moments together. Her excitement escalates with being photographed. It will surely be a secret moment shared only between the two of them.
