"My name is A Gao, maybe I can help you."
"First, I am not a god. Second, this is just a transaction. Third, this is just a contract. Fourth, it depends on your mood."
A Gao walks around every corner of the world, always accompanied by a young man dressed in black. They are neither companions nor enemies. As long as you feel despair and hope at the same time, you may get help from A Gao.
