━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
I am lonely.
That is the only thing I know for certain.
A white ceiling. White walls.
The bed, the pillow, the issued clothes—everything was white and inorganic.
Earl sat on the bed, hugging his knees.
Deep in his chest, there was a sensation of seeking something.
But he didn't know what it was.
When did this emptiness begin?
—Until yesterday, it wasn't like this.
Performing assigned tasks, eating prescribed meals, sleeping as scheduled.
That was enough.
That alone was enough to feel fulfilled.
He believed that was "happiness" for humanity.
