Although Ling Yuanai is the King of Hell, he has been entangled in a little nightmare for tens of thousands of years. So in order to find the answer to the dream and find out the truth of the matter, she came to the human world. She thought that after joining a ghost-detection club, she only needed to catch ghosts. Just kidding, this was a matter of minutes for her. It couldn't be easier. But she didn't expect to be tricked. They even take care of human cases. What's more, she was pestered by Mu Yingyan, who claimed to be a domineering president, and insisted on dragging her into a relationship. Thus began a journey of search, exploration, deciphering and emotion.
Although Mu Yingyan is a domineering president, he is favored by Ji Fei, a ghost messenger, who says that if he doesn't help him solve human cases, he will take his soul away, so he has no choice but to accept his oppression. Fortunately, he met his goddess Ling Yuan Ai, but no matter what, the goddess was the motivation for him to do everything.
