Two trains roared past each other in the dark sky, traveling quickly on the narrow track between mountains. The space was cramped, but he still rushed forward without hesitation. They pass each other and embark on their own journeys, rushing to their respective destinations, waiting to meet the next train and tell the next story. Huniu will also meet another person who makes her heart beat. We are all waiting for one story after another. And Xu Yu, when will Lin Mu have a story with you? This is a story about a secret love. Three years of secret love slowly took root and sprouted due to the appearance of summer. Lin Mu approached Xu Yu step by step from simple liking to deep love. During this period, there was sweetness and sourness but more of the fragrance of first love. I don't know when Xu Yu started to feel nervous and shy when seeing Lin Mu, and he was attracted to her unknowingly. This is a secret love story between the two of them. In those years when I was with you, the sunset filled the high school classroom. What was beautiful was not the warm sunset, but the desk and chair you once had when I looked at it from my perspective. Sand and stones are moving wildly outside the glass window. The beauty is not the blowing wind, but the place where you once stood when I look at it from my perspective. The barbed wire fence separates the snow-covered playground. The beauty is not the pure white snow, but the fact that I once stood there and turned around and saw you. In my eyes, there is no good or bad weather. Those that have special meaning are all because you were there. The weather is different, you are always you. Xu Yu and Lin Mu will be together forever
