The Madam Is a Little God of Wealth

Cai Xiao'er is a candidate to become the God of Wealth, and her first visit to the human world is for a trial. But she loses the key that would let her return to another world. With nowhere else to go, she muddles through and dents someone's car. From then on, she sticks to the owner.

Other people go out and pick up cats and dogs. Jing Xi picked up a lunatic. A lunatic who claimed to be the God of Wealth.
