Nami is 26 years old, married for one year, with no children. A graduate of a prestigious women's university, she was raised in an elite salaryman household and is known in the neighborhood as a popular, beautiful housewife. Her husband is an elite trading company employee, working in the same field as his father, and is forced to spend half of each month on overseas business trips. The unusual story of how they met was when she spilled coffee on his pants at her part-time job at Ann○ Mirrors, leading her to help him clean it. Though kind and skilled in bed, her husband's frequent absences leave her sexual desires unfulfilled. As a result, she began arranging mixer parties with her college friends, seeking new excitement.
