One day, Shohei's father brought home a young and beautiful woman. Her name was Sanae. Eventually, Sanae and Shohei got married, and she became Shohei's mother. Shohei lost his mother at an early age, so he had never been used to having a woman in the house. It was also a shared life with Shohei and a beautiful woman whose age hadn’t changed much. It was a strong stimulation for Shohei. And that day would come. Shohei couldn’t control his sexual desire and committed a crime against Sana.
