I am Xu Wu. I have a sister named Xu Huan.
Xu Huan's future is filled with laughter and laughter, but my future is like a vast fog, with no future and no light.
I hate her because of her. My soul has been left in the world forever. I have seen the world of mortals. I thought I should have been left in the fog to receive punishment alone. But she pulled me out. It was so scary. Xu Huan. Since you pulled me out, we should be entangled forever until death
Purpose: Mutual redemption
