Between heaven and earth, blue is the first forgotten concept.
When the sky and the river fade to gray in the eyes of the world, only Zhiwei can still see the disappearing blue. She threaded her needle and thread, trying to keep the color on the embroidery, but in an unknown corner, she was alone against the fading of the whole world.
Until he met Obsession - an ancient dead soul whose own existence was slowly dissipating. He followed the traces of color she retained, stared at the lonely blue on her embroidered face, and told her softly:
"What you saw was not a vision, it was the truth."
It turns out that she is not an alien, but the only one who can hold on to the embers of civilization in this oblivion that sweeps everything away.
