On a sweltering summer day, I was supposed to have dinner with my wife's family. While my wife went to pick up her mother, I ended up alone with my sister-in-law, Reiko. She was beautiful, kind, and always carried a calm, gentle presence. The situation that day began to shake my rationality. As we waited for my wife and mother-in-law, a simple act of opening beers together turned into spending the entire night alone when a massive blackout suddenly occurred. In the unexpected darkness, my heart wavered—and seeing Reiko frightened, uncontrollable emotions began to stir within me.
