An Ning is a student dog and the office's exorcist. The kind of low-level people who are most oppressed and exploited by their bosses. No matter how low-level a person is, he still has magical powers, and his ghostly figure always appears in recent haunted incidents. He is as elusive as a phantom in the water. Every time he looks at An Ning, An Ning always wants to lift the table and say, "I am not your food."
