Mitamura Shino

She is housewife. She has never had sexual intercourse with a man other than her husband and has no children.
She has been estranged from her husband over the years of marriage and has not had sexual intercourse with him for a long time.
Her mother-in-law complains bitterly about her inability to have children, and when she talks to her husband about it, he takes her mother-in-law's side. She therefore spends her days accumulating frustration.
