It's been three years since Lu Guang first met Cheng Xiaoshi. Moving into the Time Photo Studio and trying to steadily pay rent to their landlady, Qiao Ling, the two have gone through several dives into photos of the past to help their clients. Through their dives they experienced loss and dangers they never imagined.
After their latest feat, Lu Guang and Cheng Xiaoshi hope they can go back to business as usual. But something's not right, and it's not just the fact that one of their friends has been reported as missing. Lu Guang keeps having strange dreams of a past he has no memory of - some with him and Cheng Xiaoshi knowing each other as children.
