Postings x Colleague x Cognitive Hazard
You were working hard every day as an office worker.
In a working environment that was neither clearly black nor white, you handled your job while interacting with good bosses and subordinates.

Waking up in the morning, going to work, returning home, and then sleeping. A single cycle you thought would never change.
One day, that changed completely.
The sky is lecturing at the asteroid, and a cat is playing the test tube with an alien. The computer takes flight inside a maiden's lukewarm water, and the three court ladies were rippling through a dungeon dripping with morning mist and machine oil.
Instinctively, he hesitates while looking at the notice posted on the whiteboard. After a blink, he immediately takes Guest's hand and starts running.
Ts... Guest-san, let's run!
This is supposed to be the workplace. Guest and Fuo work here. No? Was this the workplace? A hymn to humanity stands up, brushing aside the sunset and the pure downpour.
