.......................................................................

Tale of the Nine Tailed is very similar with a non-human ML and an FL who can see ghosts. The spookiness and vibes are very similar. Tale of the Nine Tailed has historical scenes in flashback similar to The Haunted Palace.

FL - a shaman has a crush on ML.
The ML gets possessed by being an Evil spirit.
FL is on mission save "ML".
The Evil being is absolutely 'adorable brat'.

- The Haunted Palace focuses on spirit possession, while AOS is soul possession
- Soul swapping (powerful character's soul ends up in a "weak" mortal body)
- Sageuk kdrama, palace conspiracy with fantasy element
- Main leads become reluctant allies

In 1867, Sin Jae Hyo leads the Dongrijungsa, which teaches pansori (traditional Korean musical storytelling). A young girl, Chae Seon, who wants to perform pansori, appears in front of him. Chae Seon has dreamed of performing pansori since she first heard Sin Jae Hyo perform when she was little, but Sin Jae Hyo turns her down because women are not allowed to perform pansori. Chae Seon then disguises herself as a man and enters the Dongrijungsa to learn pansori, but Sin Jae Hyo doesn’t accept her as his student.

One day, he hears Daewongun, the most powerful man in Joseon and the father of the King, is going to hold a national competition of pansori performers known as “Naksungyeon”. Sin Jae Hyo decides to teach Chae Seon, who has a true voice to perform “Chunhyangga". If anyone finds out that Chae Seon is a woman, Sin Jae Hyo and Chae Seon will both face death.

However, after waking in the hospital, Han Joon Oh finds himself possessed by the vengeful spirit of Do Ha, a nobleman from ancient Korea, determined to seek justice for his betrayal and death.

If you liked Bon Appétit, Your Majesty, you might enjoy The Haunted Palace because both dramas mix romance with a supernatural twist in a really charming way. Each story brings the leads together through unusual, magical circumstances—one through enchanted food and curses, the other through ghosts and haunting mysteries. They share a similar vibe of light fantasy, warm chemistry, and a touch of mystery as the couple uncovers secrets and grows closer while dealing with the supernatural elements around them. The overall tone feels whimsical but emotional, making The Haunted Palace a nice follow-up for anyone who enjoyed the magical-romantic atmosphere of Bon Appétit, Your Majesty.

On the eve of her 19th birthday, Mizuki is grappling with a recent family tragedy, a cheating boyfriend, and a betrayal by her best friend. In despair, she flees to a dilapidated estate where she encounters Adam, a mysterious figure playing a familiar melody. Drawn to him and the house, Mizuki uncovers a haunting connection. As the full moon approaches, her boyfriend and a few schoolchildren work to unravel the dark secret from 19 years ago and save Mizuki.

Both are about ghosts or demons threatening the palace and different people trying to either destroy or control the beings.

Both are historical /palace setting dramas, with elements of suspense and some horror.
Both have interesting and fresh plot.

Mirror of the witch and The Haunted Palace treat about evil spirits which endanger the Royal Family.
Both have romance and comedy too, and different ghosts which pop out sometimes.
Mirror of the Witch is darker and also more complex (story and characters).

Even though they’re different, they share this beautifully haunting energy that really pulls you in.

The Haunted Palace leans into gothic mystery and ghosts of the past, while Lovers of the Red Sky wraps you in a dreamy, historical fantasy with gods, demons, and a love story cursed by fate. The visuals are stunning in both, moody and cinematic in Palace, rich and mythical in Red Sky.

What really connects them for me is how both shows explore love, loss, and forces beyond our control, all through complex characters who are trying to survive a world shaped by the supernatural.

Deity human relationship
FL has a shaman background as well, her grandmother plays a big part in her life
