That year, when you pulled me up from the dark abyss and gave me happiness, I once asked, "How long can the happiness you give last, one day, one month, one year, or ten years." It was early summer, and you were standing in a white shirt with a warm smile. You looked at me thoughtfully. "If there is no accident, I think it will be a lifetime!" I said, "What if there is an accident?" "Well, then I allow you to find the next stop of happiness." Then, in the confused early summer, you grinned and smiled. Is your smile so beautiful?
