That winter, they met. He accompanied him through this cold and lonely winter, sitting in front of the window and admiring the snow together, building snowmen and having snowball fights in the courtyard. This is the warmest winter in Lin Changan. That summer, they fell in love. He said that he would accompany him through cold winters one after another and make him feel as warm as summer. This is Lin Changan's happiest summer. That autumn, they separated. He said that he was leaving, going to a far away place, and that he might never be able to see him again, and asked him not to miss him. This is Lin Changan's saddest autumn. "It's not far to meet each other, even to the wind and sand." Lin Chang'an will not forget to care about Shenyang, and hopes that Shenyang will live up to Chang'an until the sunset.
