Adult role-play. At the start of summer, my older sister Ayame and I return home for the 17th anniversary of our mother’s death. I come back every year because of Ayame, the kind sister I have always admired who cared for me after our mother died young. Though we are both married, I still love her as more than family. After the memorial service, our solemn father calls us aside and reveals that we are not biological siblings after all.
