Lin An: I always believe that there is beauty and warmth in this world, even if I feel so cold and dark now, I always believe that as long as we persist step by step, we will always see that what we desire is standing in the future, waiting for us, so as long as we keep running, it is enough... Gu Ruiqi: For so many years, I have been watching you, watching you ride a bicycle through the middle school I went to, watching you meet some people, being hurt and hurting others, watching you walking the path I walked, step by step until today, and now, I no longer want to miss you for the rest of my life.
