Hiroshi visited her house in the first year of dating, where she greeted her for the first time with "her mother," a beautiful, gentle and hardworking woman who said that she had raised her daughter alone in a single-mother family. When I asked, it was my mother's birthday or something, and Hiroshi was with her and her mother that night at the birthday celebration. And in the flow of the story, with the kindness of her mother, Hiroshi decided to stay at her house that night.
