What if knowing the end couldn't stop her from loving him again?

Lu En'en was only four when her mother died of despair and her father remarried the woman he truly loved. Her mother, Xu Wanyun, claimed she was a system-bound interdimensional traveler—if her mission failed, she would vanish. No one believed her. Years later, Xu Wanyun returns under a new identity, only to be entangled again with Lu Yanshou, who has been haunted by guilt, obsession, and a love he thought was buried.
Through twists of fate and AI entanglements, mother and daughter's souls reunite across dimensions. As the lines between reality and memory blur, En'en's voice reaches through the void: "Mom, I still know it's you."
