Five years ago, Yuna married a man who was a client of the jewelry wholesaler where she worked. Although he was quite older than her, she was attracted to his kindness and decided to marry him. Yuna wanted children, but as they struggled to have children, the frequency of sex decreased. Her husband began to leave the house frequently to buy goods overseas, and she felt a strong sense of loneliness in her life. Yuna, who has always liked alcohol, began to drink outside when her husband was not around. One day, she met an older man... While she was consulting him about her family troubles, she was swept away by his kindness and he seduced her... She fell into the decadence of pleasure.
