As a god in charge of contracts, An Yeyu has never understood why humans in this plane... Either ignore contracts and violate the contracts they have made; or they abuse contracts and deceive those ignorant children. For his year-end bonus, An Yeyu finally couldn't hold back and came to the "fairy tale plane" and transformed into a witch...
Concept: Everything in the world has its pros and cons, and the witches in fairy tales naturally do not have to be villains.
