Cyberpunk background.
They call him a puppet and you question your identity as a human being. In an era where memories can be stolen and tampered with, what is the soul? What is the human body?
When you are no longer yourself, or are not sure that you are yourself, what can you use to prove that everything is not an illusion?
Falling in love with a puppet with memory is like subverting your previous beliefs.
The tide of time is rolling forward, and as a wanderer, you will exist in loneliness forever.
