To save a deceased Cheng Xiaoshi, Lu Guang returns to the beginning of their journey, traveling back to their college days in the city of Bridon. While there, Cheng Xiaoshi discovers a photograph of the city seemingly sent by his long-lost father. Eager to find the truth, the duo ventures into the local Chinatown, only to get caught up in a series of scams and a mysterious fire at a local academy.*

As they navigate these dangers, they encounter new figures with hidden agendas: the popular model Xia Fei, the eccentric Chinatown leader Vein, and the enigmatic Liu Xiao. This arc serves as a bridge that explains how Lu Guang understood the "butterfly effect" of their powers and establishes the "destined dead end" he has been trying to break through multiple loops. Though chronologically a prequel, it introduces core antagonists and themes that directly set the stage for the upcoming Season 3.
