I have no idea where they came up with the name for this drama. There’s no fairy land nor are there any fairies. What I describe below is not a spoiler. You need to understand these things beforehand in order understand the drama. It’s about an alien race whose ship crashes on earth. They are stranded and fragments of their ship is scattered all over earth. These fragments are made of jade and have special powers. If a person has an extreme obsession the jade fragment can give life to that obsession and their spirit can continue living for hundreds of years trying to fulfill that obsession. The aliens (called heavenly soldiers) have the job of getting rid of these obsessed spirits because after a period of time they become very evil. The male lead is an obsessed spirit that is very good and has managed to contain and control his obsession. He was helped by a female heavenly soldier that died to protect him. She gave him her heavenly soldier bracelet that gives the wearer special powers. He becomes a spiritual doctor and cures obsessed spirits of their obsession before they turn evil. Heavenly soldiers (the aliens) and the obsessed spirits are natural born enemies.

The female lead intrigues the male lead because she can do things she’s not supposed be able to do. She’s an ordinary human but relics of the alien race, like its sacred peach tree, responds to her touch. He’s a very cold person but he rents an entire floor in her families large ancestral home because he wants to figure her out. Their story and their past lives were quite interesting. I thoroughly enjoyed unraveling their mystery. They also have a great romance with some nice kissing scenes. I liked that they had both romance and mystery to their story.

There are some nice second and third couples whose stories are well fleshed out. For a good two thirds of the drama they mostly help obsessed spirits and the stories were pretty deep and interesting. Of course along the way romance blooms, couples bicker, there’s lots of comedic relief and then evil plots start forming behind the scenes. The last third of the drama it starts to get angsty and sad. So many things happen so quickly. It goes from cute romcom to melodrama. But this is very typical of Chinese dramas lately so I wasn’t surprised. I would have preferred either a light fluffy romcom or a melodrama but not both combined into one.
But that being said, I still really enjoyed this drama. It has a pretty deep storyline that kept me hooked and a satisfying ending that made sense. There were no loose ends or unanswered questions. It reminded me a lot of The Goblin. Especially when the male lead who is an obsessed spirit, and the second male lead who is a heavenly soldier become good friends. Not only do these sworn enemies have a great bromance, they even cohabitate. In the beginning when they were using their powers to throw objects across the room at each other I had major Goblin vibes. It’s not as good as Goblin but it’s well worth the time invested in watching it.
