In 2026, Lin Yan, a junior at Jiangzhou University, founded the public welfare student aid system "Weiguang Mutual Aid" to use AI technology to help poor students avoid the loan shark trap. Her mentor Zhao Jingming used a high-paying position as bait to force her to delete the system's ethical restraint module - she refused. From that day on, she was involved in a dragnet set by Starlink Capital: framed, falsely accused, imprisoned, company bankrupt... Finally, in the late autumn of 2046, Lin Yan breathed his last on the hospital bed.
Xu Wu, standing at the funeral, was once a recipient of Lin Yan's help, and later became her closest comrade-in-arms and lover. She took over the notebook with frayed edges and Lin Yan's unfinished wish. With the assistance of the technical genius Yan Kuan, Xu Wu launched the "Yuan Sequence" cross-temporal information projection plan to send early warning information back to 2026. When Lin Yan received the first mysterious text message back then, he did not know that it was a lifeline handed over by his future lover across twenty years.
