Qiao Yu is an ordinary night shift clerk in a convenience store, living a plain but warm life. Late one night, a mysterious old man handed him an ancient pocket watch, and his world changed completely. Whenever Qiao Yu falls asleep, he will be pulled into a strange world called "Countercurrent Space", where the flow of time is different from reality. He must help the lost souls in the space to untie their obsessions in order to gain short-term peace. However, his selfish relative Qiao Zhiyuan somehow learned the secret of the pocket watch and began to snatch it by any means necessary. Qiao Yu is forced to be involved in a game that spans reality and another space. He must protect the ordinary life he cherishes while helping others find their original aspirations. During time travels, Qiao Yu resolves resentment with gentleness, lights up the darkness with kindness, and gradually discovers the true secret of the pocket watch - not to control time, but to heal people's hearts.
