At the end of a sweltering summer, I return home for the seventeenth anniversary of my mother's death. No matter how busy I am, I come back every year because of my adult stepsister Yuka, who cared for me like a mother after ours died and became the woman I admired most. We are both married adults now, but my feelings for her have always gone beyond sibling affection. After the memorial service, our father reveals that we are not biologically related... This is an adult step-sibling role-play.
