In this chapter titled "First Affair," her gradual immersion into a relationship with a man of her own choosing is depicted in vivid detail. Then, Izumi Hanamura craves a body different from her husband's. What fills the void in her heart is a stimulating encounter that makes her forget everyday life. Every work captures the raw desires and conflicts that married women show outside the home, leaving nothing out. Viewers can experience the tension of the moment they cross the line and the subsequent release, as if they were right there on the scene.
