Shinichi was born when Michiko was a student. After graduating, I started a business with my husband, but I was busy with work and had little time to spend with Shinichi. On the other hand, when I was with him, I was just fond of him, and Shinichi was also spoiled. However, that relationship continued even when Shinichi became an adult, and eventually he began to have a physical relationship. Michiko and Shinichi went on a trip alone because they had the eyes of their father in the house. No one cares about it here.
