Her love of animals led from a part-time job to permanent work at a pet shop. She married a hotel employee four years her senior, moved away when he was transferred and spent her days consumed by housework. Once child-rearing settled down, she took a restaurant job three days a week to ease her boredom and loneliness. Her husband invited her to a play staged by Takahashi's theater company, and she became a fan. Later, she attended the cast party alone and crossed the line. From then on, she repeatedly visited Takahashi at home to continue their affair.
