She was the little princess most beloved by the Celestial Emperor of the Divine Realm, and should have lived a carefree life there. Unfortunately, she had a falling-out with the High God Li Nezha and, in a fit of anger, came down to the mortal world.
After arriving in the mortal world, she opened a little shop and has kept it running for tens of thousands of years.
The shopkeeper decides what to charge based on her mood.

As time passes, the shop's collection of objects and memories grows ever larger.
Every object here has its own story woven around it.
