At first she thought it was a prank, but everything that happened the next day turned out to be completely identical to the phone's prophecy. Even more bizarrely, she successively picks up mechanical prosthetic eyes and mysterious packages from the future, and even discovers that hidden above everyone's head around her are secrets unknown to others. As each prophecy comes true, she gradually realizes that what she picked up is not trash at all, but a warning from the future. When the future and reality intertwine, and when destiny can be rewritten, is she saving herself, or stepping step by step into an even more terrifying trap?
