In a big modern city, there is a small photo studio called Time Photo Studio. Very few clients come here. The store is managed by Cheng Xiaoshi and Lu Guan, two individuals with exceptional abilities. They collaborate and use their supernatural talent to fulfill the clients' requests. There is a rumor spreading on the internet that there is a devilish creature that can appear inside any photograph and fulfill the owner's request...
Note: "Shi Guang Dai Li Ren" translates to "Time Agents" in English, but to capture the original meaning and tone, "Time Photo Studio" is used instead.
