I, Lin Zhi, could see the color of the sound, until I met Jiang Xu - his piano sound was a silent gray. Because of an own goal in the dormitory, I was forced to become a roommate with this campus legend. From the awkward "Three Chapters of Agreement" to becoming his only listener, I tried to find color for his dark piano sound. When his family asked him to put down his bow forever because of his future, I held his hand tightly for the first time. "If they say your dreams are dust," I said, "then let's turn them into stars together." This is a story of seeing, healing, and growing side by side. About how two lonely souls recolor each other's world.
