What Can You Offer to Rewrite the BE Line?

24-Year-old Xia Linye encountered a plane crash on his way back to his hometown to attend a junior high school reunion, and his consciousness went back to the third-grade junior high school class nine years ago (2015). At this time, there are two voices in his mind: the crazy personality "Madman" who claims to be "my past self", and the girl "Xu Niantang" who is suspected of being dead and residing in his consciousness. He carries a triple countdown: 90 Days: Prevent Xu Niantang from falling to his death from the 12th floor; Year 9: Avoid future air crashes that will destroy the west of the city; Present moment: Confrontation with the whispers of "madman" and "Xu Niantang" competing for dominance in the mind. With broken adult memories and a heavy sense of guilt, Xia Linye must use his strange "retrospection" ability to rewrite the chain of fate of the successive deaths of close relatives and friends under the bustling appearance of youth and the undercurrent of this declining city, and uncover the truth about his split personality and the shadow of the city.
