Akari, 28, has been married for five years. After graduating from nursing school, she married a surgeon at the hospital where she worked. Later, her husband transferred to a hospital in the same chain, and now they work at different hospitals. Their relationship is not bad, but due to their busy schedules, they rarely spend time together. After her husband's transfer, their intimate life has significantly decreased. She has been rejected by other married women's advances, and for the past two years, she has been sexless. Amidst her stifling days, she accepted an invitation from a married man for a trip, hoping it would improve her relationship with her husband.
