At Time Photo Studio, Cheng Xiaoshi and Lu Guang use their complementary powers to enter photographs and fulfil their clients’ unresolved requests. Each mission draws them into lives shaped by regret, loss and difficult choices, while Cheng’s compassion repeatedly tests the rule against changing the past. When their cases become connected to a dangerous mystery, the consequences reach the studio itself.

Following the attack on Time Photo Studio, Cheng Xiaoshi and Qiao Ling become entangled in a dangerous investigation while Lu Guang fights to recover. As a mysterious enemy uses photographs to control others, the group uncovers a tragic family history and a conspiracy surrounding their powers, forcing them into a desperate struggle to protect one another and expose the mastermind behind the escalating violence.

When a photograph connected to Cheng Xiaoshi’s missing parents is discovered, he and Lu Guang travel to Bridon in search of answers. Their investigation leads them into the aftermath of a devastating academy fire and the lives of several strangers hiding conflicting motives. As buried connections gradually emerge, Lu Guang quietly struggles against the fate he fears may be awaiting Cheng.

After the Li Tianchen incident came to an end, the Time Photo Studio returned to a superficial calm. However, the news of Xia Fei's disappearance once again plunged everyone into the crossroads of fate. With Vein's return and Qiao Ling's awakening powers, Cheng Xiaoshi and Lu Guang gradually uncover the secrets of the Bahati fire case. Cheng Xiaoshi's father, Cheng Weimin, and mother, Shao Yuanyuan, also seemed to have intricate connections to it. As the investigation deepens, Liu Xiao, from a mysterious organization, begins his actions, and the intervention of Bridon police officer Jae adds uncertainty to this quest for the truth.
