Flowers Fade
Aya had watched countless flowers wilt and die. countless petals fall to the floor to be swept away, wrinkled, browning, and drying. That was the way it was with flowers. Each just fading its way out of existence on its own, no single rose being mourned by another. The dead plants and flowers that filled the dumpsters behind the shop, just as many stems and leaves as empty cigarette boxes, went unnoticed by the customers, all seeking temporary beauty and life in a vase.
Aya worked in a flower shop. And never once brought a bloom to his sister. Because Weiss, the hunters of the night, the men with the Devil's own, were terrible, terrible, corrupt and dying flowers, and when they died, no one would notice. Fujimaya Aya, as opposed to Fujimaya Ran, was a beautiful, wonderful flower, but so silent, so small, and so helpless that no, no one would notice if her monitor flat lined.
Aya never brought flowers; no one would notice the mess of petals on the floor to clean it up for a girl and the devil brother they had already forgotten.
