Spending winter break in Tokyo, I visited my brother's wife. My sister-in-law Kaori was as kind and warm as always, greeting me with her usual smile. It had already been five years since my brother passed away in an accident, and Kaori had continued living alone as a widow. She still hadn't remarried. When I asked, "You're beautiful, Kaori. Why not move on from my brother and think about marrying again?" she gently smiled and said, "You're right. Since you've come all this way, why don't you stay the night?"
