Sorry, Bailong

There has always been a knot in my heart. I made a mistake when I was a child. I wanted to explain it to Fa Xiao, but I couldn't. Later, we drifted further and further apart. Later he moved. I finally looked forward to meeting him for the first time in ten years (I still couldn't speak), but we parted on bad terms. I thought I would miss it, but I never thought we could meet in another world...
