Sayuri, a wife who works as a cleaner to support Atsushi, the painter's husband who cannot sell. One day, the president of a cleaning company asked me to clean the mansion of Amagi Koshiyama, a major figure in the Japanese Western-style painting world. Koshiyama stares at Sayuri's body as if she starts cleaning according to the disciple's instructions. "Have you ever done a model?" Sayuri was surprised at the sudden question. On the condition that she criticizes her husband's painting, she takes off her clothes in front of Koshiyama.
