This is a story about ordinary people and mediocrities, and about a world inching toward destruction. Feng Xun had often imagined saving a beautiful girl at the last possible moment and then embarking on a heart-pounding romance with her, but it had never happened. "Because it's just a delusion," "I don't have the power," "Mercy is a privilege of the strong," "I'm just an ordinary person." That's what Feng Xun told himself. But what did the scenes he experienced night after night in his dreams mean? Why did he relive them again and again, struggling forward through frozen time, saving a girl who had jumped onto the tracks before everything shattered completely? After 22 ordinary years, Feng Xun finally awakened to his supernatural ability that winter, unaware that the bells of the apocalypse were ringing.
