He originally thought that she had returned to dust, but during a mission, Lu Jin saw "S-09" in his military capacity - an artificial entity that had Su Tang's appearance but was called an "armed consciousness carrier".
Is she still "her"? Or is it just a high-level program that mimics human emotions?
Between "the rebirth of his lover" and "national orders", between "ethical collapse" and "emotional truth", Lu Jin embarks on a road of escape from which there is no turning back. He wants to save the woman who has accompanied him through the four seasons of the world, whether she is now a human, an AI, or a "variable" in between.
This is a science fiction story about "identity", "consciousness" and "love". She broke free from the experimental number and learned to cry, dream, and love again. And he also found his reason as a "human" in the struggle of betraying the system again and again.
In an age where technology can awaken memories, how do we define a person? Is it a heartbeat? Is it flesh and blood? Or - the will to be loved?
Very good thinking
