My father remarried, making Shihori my stepmother, but she eventually left. Several years passed, and I received a message from Shihori inviting me to go on a trip together after all this time. I decided to meet her again. When my father and Shihori were still married, their relationship suddenly deteriorated, and I could do nothing but comfort Shihori as she cried every day. Gradually, my father began staying away from home, and my bond with Shihori grew deeper. In the end, it felt inevitable that we would become lovers.
