In the fictional town "Wanghai Town" on the southern coast, there is a seemingly ordinary 24-hour convenience store - "Xiaoman Convenience Store". The owner, Lin Xiaoman, is a "Buddhist" girl who has just graduated. Her biggest wish is to guard this small shop inherited from her grandmother, listen to customers' stories every day, occasionally catch up on dramas, and live a peaceful life while "lying down". But ever since a mysterious man, Shen Che, walked into the store on a rainy night with a discontinued antique pocket watch, strange "time-space superposition" phenomena began to appear frequently in the convenience store: sometimes old snacks from decades ago would suddenly appear on the shelves, sometimes you would hear radio sounds that did not belong to this era, and you would even occasionally encounter "ghost customers" wearing old-era clothes.
