Imagine that one day, a universally acknowledged property of time is bended. What is that property? Write about the new world under that setting.

Rather than being linear, time is a loop in this new world. People moving forward to the direction of "future" are only making ways to their past. This is a good news for those with a joyful past, but not so much for those with a rather dark history. People who seek to avoid their history are now ruminating over the causes of their misery, while those who seek to relive their past are doing the same thing, only to amplify those factors behind their happiness. Yet, the happiness of some is built on top of the exploitation and manipulation of others, and it is under this setting that a war over the past commences.
