A hidden world lies within an unnoticed cupboard. An unexpected event sparks a cross-dimensional connection between Little Sizi and Liu Chang'an. From then on, Little Sizi is no longer afraid of cold or heat. But as a superb caregiver, how can Liu Chang'an stop there? Delicious, fun, or beautiful—anything Little Sizi asks for, and Liu Chang'an, like an almighty transport captain, will haul it all to the Tang Dynasty... Little Sizi: "Little Sizi wants it..." Liu Chang'an: "Here I come!" It's a seemingly peaceful, child-loving routine, but behind the scenes, it's a two-way journey across time and space... [Note: This is not a sweet romance.]
