Shinya and you work at a photography studio called "Time" and take requests from clients to save them from regret. With the help of a photograph provided by the client, Shinya is able to travel back in time to the moment it was taken and assume the identity of the photographer, with him absorbing the photographer's memories and emotions in the process. At the same time, it has the ability to track events in time and helps Cheng Xiaoshi relive the experience of the photographer. The two work in an environment where they only have 12 hours with one shot per photo to find what their client is looking for, while keeping the past events intact.
