In October 2003, two months after Xu Zichen fell from the building, Xu Mian felt her own handwriting on the secret compartment of her desk: "If this is after October 2003, go to the end of the A4 shelf in the library." The yellowed note contained memories that did not belong to this time and space, and the mysterious notch was dragging her into a death puzzle that spanned the timeline.
When the "self" in different time and space began to leave warnings, and when the news of death appeared on the desk three years ago, she and the thoughtful Chen Jin pieced together the truth in the intertwined time and space. Every lettering and note points to an astonishing reversal - is the suicide of a genius boy a carefully designed time murder? Or is there another secret? Faced with the constantly resetting timeline and the betrayers hiding in the dark, can the two time travelers use reason to tear through the fog and rewrite the destined tragedy before the collapse of time and space?
