At the end of the summer, when the heat remained, I was returning to my parents' house for my mother's 17th funeral. Every year, no matter how busy I was, I would give a reason to go home because of the presence of my older sister, Yuka. My sister is a woman I admire who has been taking care of me on behalf of my mother since I lost my mother when I was a child. We are both married now, but I have always had feelings for my sister that are more than siblings. Then, that night, my father called me at the end of the ceremony and confided in me that the two of us were not real siblings.
