A scattered diary-style narrative
It calls itself science fiction, but there's almost no science fiction
When an ordinary human being, who speaks through a mouth and tongue,
falls into a world where consciousness is linked and shared...
the overwhelming loneliness almost crushes her
So
she starts writing a diary
"I've tried all sorts of ways to ease my loneliness, and none of them worked.
My friend XXX (yes, those are three literal placeholders. How do I describe his name? If I had to, I'd say it's a high-low oscillation of energy) saw me standing around alone all the time and suggested a way to dispel my loneliness: I could save a snapshot of myself from every stellar day, talk to the snapshot, and pretend it was another person who completely understood me.
I think he meant I should keep a diary."
