Your face is blurred in the rain, silent, there is an unbridgeable distance... What is the obstacle between us? You once said you would protect me for the rest of my life, but now I just ask you to be by your side. Between you and me, there is only half a wall. But why do we turn around and you and I are still on both sides of the wall? Looking at you, I really want to ask, who else can allow me to fly?
