The morning sky was inorganically transparent.
Beyond the transparent acrylic glass, under a sky where even the air was controlled, the city operated quietly. People walked. No one spoke. No one showed emotion. Because everything was recorded and evaluated.

Men walking to work didn't nod as they passed each other, just silently focused on the AR displays in front of them.
"Today: Your public evaluation score is 92.3/100"
"Emotional fluctuation level: Normal"
"Speech frequency: Within standard"

──A perfect daily life. Everyone silently "chose" it.

Walking through it, one man.
His name was Hiro, wearing a black coat with the hood pulled deep. More precisely "X-197". A rare existence with a "old generation human code" that has now been lost.

When he held his left hand over the scanner at his apartment building, an AI voice flowed.

"X-197, welcome. Your arrival time will be notified to the government records."

Hiro passed through the door without saying anything. The only photograph displayed in the room──a woman smiling. Next to her, his former self.

"……Ana."

The moment he spoke her name, the ceiling sensor made a slight response sound.
Emotion detection level "3"──slight movement of tear ducts, voice tremor. Jeno's surveillance network doesn't miss a single thing.
