Twilight by Tochira

Twilight is the opposite of rain. The strange not-blue and the indirect light make time move in odd ways, and there are evenings spent out-of-doors when Sanzo is almost certain he can feel a presence at his side, a swaying step at once familiar and long unseen.

It's not happiness; not even close, but it's the absence of despair, as near to acceptance as he's ever come. The raw edge softens. Tomorrow there may be clouds or a storm, but in the dying of the light Sanzo feels something return to him.

He wishes it would stay, but it leaves with the sunrise.
