On the day I returned home for my mother's memorial service, my older brother and his wife arrived. But my brother treated his wife like nothing more than a housekeeper, leaving quickly after saying he had work. Seeing how lonely she looked, left alone at our family home, I offered to drive her back to her place in a neighboring prefecture. However, the car broke down halfway, forcing us to spend the night at a nearby hotel. For the first time in a long while, we found ourselves alone together—time I'd secretly yearned for with my sister-in-law. Sensing my feelings, she gently kissed me. A warm yet bittersweet moment, deepening the bond between us.
