Do you know? I always think about the unhappy fifteen-year-old you. I want to hold the crying you in my arms. I am not sure whether my shape will collide with the world at every turn. I will heal those wounds one by one for you. That year, the most difficult exercises were just a few lines of notes. But now I always love to recall you who refused to admit defeat, whether the sky would stop raining, whether it would clear up, and whether happiness would be waiting for you and me at the end. No matter how many tears we shed, no matter how loud we cry, we will never be able to go back to the past; no matter how many trees we climb, no matter how many roads we walk, we will never meet the confused you again... From now on, you will no longer be wetted by the rain, because we are each other's protection and protection. From now on, you won't feel cold because we warm each other's hearts. From now on, there will be no more loneliness.
