A very touching passage: "As we walked, it was already autumn. In the blink of an eye, it was a day. In the turn of a head, it was a year. In the turn of a head, it was a lifetime. Those days in the past, whether they were wronged or happy, have become the past and can never be regained. Keep moving forward and don't look back. Flowers will bloom along the way, and so will the road ahead.
