In this orderly future city, watch repairman Gu Chuan just wants to guard his small shop and spend his whole life with those jingling old times. However, an unexpected "repair" allowed him to "repair" a crack in reality, and also exposed his rare talent as a "synchronizer".
The cold and rigid "World Line Stability and Anomaly Countermeasures Bureau" came to his door and forcibly dragged him from an ordinary person into a bizarre and abnormal world. From a desk lamp that speaks talk shows, to mythical beasts that only exist in legends, to "self" from another tragic world line... Gu Chuan discovered that what he wanted to "repair" had long gone beyond the scope of clocks.
When the cold "formatting" instructions of the Countermeasures Bureau conflict with the warm human story behind the abnormal body, and when the "righteousness" of maintaining world stability requires the sacrifice of innocent "ego", Gu Chuan is forced to make a choice between becoming a qualified "calibrator" and protecting the humanity that should not be erased. Will he, this uninvited "reality repairman", become the guardian of the world order, or the biggest variable?
