i loved my fatherinlaw more than my husband... Miki Sanehama

Ten years after marrying Hiro, who was a young child from the students, Hiroshi seems to have recently cooled down somewhere against Miki and drank it every day. She is tempted to spend less time with her husband, and makes her feel lonely every day. It was the presence of his father-in-law, Tool, who lived next door that supported her heart. He was also a teacher when he was a student, and his love for Tool, which had always been good, resurrected. When he noticed that he was tempting Tool in a moment, he decided to go to his father-in-law's bedroom.
