As time goes by, I can no longer remember how many springs, summers, autumns and winters we have gone through. Still can't forget that autumn wind rustling, the autumn when we met. We came together from all over the world, just for the dreams in our hearts. In the large crowd, I passed by each other and looked back inadvertently. The other person's face has been deeply imprinted in each other's minds and remains in their hearts. Standing on our common stage. After years of precipitation, they have become acquainted and known each other, and have slowly entered each other's lives. They seemed particularly happy because of each other's presence. Their road to love was bumpy. Tolerance and longing have made them devote more time and adjustment period to this love journey than ordinary people. Will their ending be happy or regretful?
