Qiuhang, I think we must have known each other in our previous life, or we must have been a pair of lovers buried together in our previous life. We lay together in silence under the red leaves in Xiangshan. Even after many years, I still feel so sad when I see you in this life. The first time I saw you smiling and calling me Lin Xiao, the smile on your face was like the sunlight refracted from the red leaves.
