Electronic toys in 2073

I am determined to go my own way and seek warmth in technology. "

"Once you realize that the other person is just a game program, it's like falling out of love..."

★The previous work "Journey to the Edge of the World" by the same author has been released in France★

Even though the task has been completed, J still returns to the video game character Saya every day and repeats the same conversation:

"Take a drink and see! This is iced coffee with milk."

"Thanks."

"Ah, you can call me Saya!"

In 2073, humans finally mastered the dreaming mechanism of the brain. Combining virtual reality and dreams, the cross-generational DR (Dream Reality) technology became a sensation.

In 2088, J accidentally obtained a long-banned DR device at a second-hand market. Through it, he returned to the past game "Library of Doomsday" and met his favorite character Saya; in a real body experience that surpassed any virtual reality Below, Saya’s coffee shop looks much more comfortable than a real home.

Gradually, J began to wonder whether the world with Saya was a video game, or the world without Saya?

As an engineer who eliminates bugs in games, he cannot understand the bugs in his own body... In the end, was it J's actions that caused the bug to appear in Saya's program? Or is Saya a bug in the game?
