Yu Nuo's world was completely frozen that summer when Yan Baiyi turned into a vegetative state to protect him.
With great guilt and obsession, this young genius in the field of artificial intelligence did something shocking - he stole his parents' immature digital thinking technology and created a robot "Ji Yan" with all of Yan Baiyi's memories and personality.
He hid this perfect replica in a suburban villa, trying to use stolen daily life to stimulate the real Yan Baiyi to wake up in the hospital bed. He told himself that this was just a sophisticated experiment to awaken the one he loved. He must always be vigilant and not let this "work" with independent thinking ability detect the truth, let alone let himself... Be tempted by him.
From the moment he woke up, Ji Yan firmly believed that he was a human being and Yu Nuo's lover. Until he followed Yu Nuo and saw the sleeping "self" in the hospital ward.
The cold truth shattered all his perceptions: he was just a tool, a dead thing without a heart and unable to grow old with his lover.
On one side is the sleeping body in the hospital, and on the other side is Yunuo who is suffering from self-blame.
The love between the two "Yan Baiyi" is pulled between data and soul.
When outside forces begin to notice this "alien" that shouldn't exist, Ji Yan knows that he must make a choice - whether to seize this stolen happiness and replace the original body; or to sacrifice this unique "existence" to fulfill Yu Nuo's original wish and protect him from the established rules of this society.
"Xiao Nuo," he thought, "if I really have a human heart, then it must be hurting for you right now. And the only gift I can give you is 'love you until death'."
Intention: grow together and never give up
