Seven Day Cage

Ordinary white-collar workers are trapped in a seven-day cycle and find that their city has been transformed into a time cage. As the number of cycles increases, reality continues to collapse, and mysterious organizations, mechanical cyborgs, and the Space-Time Administration appear one after another. Each character carries memory fragments from different timelines, and the protagonist must piece together the truth within seven days, otherwise he will be trapped in the collapsed time rift forever.
