With just days left until its premiere, SBS’s new Friday-Saturday drama ‘The Haunted Palace’ is already capturing attention—thanks in part to writer Yoon Soo-jung, who recently shared behind-the-scenes insights into the creation of the historical fantasy series.
Set to air its first episode on April 18, The Haunted Palace is described as a genre-blending spectacle, mixing palace intrigue, fantasy, romance, and occult themes. The story centers on a fateful battle between Yeo-ri, a shaman, and Kang Cheol-i, an imoogi (a serpent-like spirit) trapped in the body of her first love, as they face off against the royal family’s terrifying eight-foot ghost.
The series is helmed by acclaimed director Yoon Sung-sik, known for hits like Mr. Queen and The Best Yi Soon-shin, and marks a much-anticipated return for writer Yoon Soo-jung, whose previous credits include The King’s Face and Cheeky Go Go.
From Ghost Stories to Screen: How ‘The Haunted Palace’ Was Born
Speaking about the origins of The Haunted Palace, writer Yoon shared:
“I first got the idea while co-writing The King’s Face. As I researched palace life, I kept thinking—there must be countless ghosts in those ancient halls. That thought stayed with me and became the seed for The Haunted Palace.”
Intrigued by the challenge of combining romance and the occult, Yoon sought to develop a narrative that would feel fresh yet culturally grounded:

“These genres don’t naturally blend, so I focused on making them flow without feeling forced. I was inspired by Korean classical works like Eou Yadam, Seongho Saseol, and Cheon Ye Rok, along with documentary films and books on shamanism.”
Casting Choices That Brought the Script to Life
Writer Yoon didn’t hold back in praising the cast, especially Yook Sung-jae, Kim Ji-yeon, and Kim Ji-hoon, whose performances she described as “perfectly aligned” with her vision.
“Yook Sung-jae impressed me with his sharp comedic timing and haunting presence as an evil spirit. Kim Ji-yeon brought Yeo-ri to life with strength and emotional depth. Their chemistry together is truly captivating.”
As for Kim Ji-hoon, who plays Wang Yi-jung, Yoon expressed total confidence in his ability to embody the complex role:

“I wrote the character without worrying about his portrayal. Viewers can expect to see some of his most passionate acting, especially in the latter half of the series.”
A Labor of Love From Script to Screen
Despite filming during extreme weather conditions, Yoon praised the production team and director for their unwavering support:
“Director Yoon trusted the script throughout, even during intense heat waves and cold snaps. The whole team behind The Haunted Palace worked with incredible sincerity and skill.”
With excitement and nerves building ahead of the premiere, Yoon concluded:

“It’s been a long time since I’ve had a drama air, and I’m both excited and nervous. The Haunted Palace is a story we’ve poured our hearts into, and I hope many people will enjoy it.”
