In the world of Korean cinema, adult films have carved out a unique place in the hearts of viewers. These works attract audiences not only with their scorching scenes but also through their meaningful content and artistic value. Over the past two decades, many Korean adult films have made a significant impact, with one standout being The Treacherous (Vietnamese title: Vương Triều Dục Vọng).
The Treacherous: A Harrowing Tale of Tyranny Under King Yeonsangun
The Treacherous is set during the Joseon dynasty under the reign of Yeonsangun, a historical figure infamous for his cruelty and decadence. His terrifying rule was fueled by an obsession with his mother’s death. Upon ascending the throne, Yeonsangun unleashed brutal revenge on those who had harmed her. But this was only the beginning of the story.
After taking the throne, Yeonsangun purged hundreds of scholars in what is known as the Second Literati Purge. Wherever the tyrant went, fear followed. However, not everyone suffered his wrath. Two men, Governor Im Sung Jae and his father Im Sa Hong, enjoyed the emperor’s favor.
Trusted by Yeonsangun, they scoured the land for beautiful women to bring to the palace to satisfy the emperor’s depraved desires. Among these women was Dan Hee, a young woman whose extraordinary beauty captivated all who saw her. Yet few knew that Dan Hee harbored a deep, vengeful grudge and entered the palace with a deadly mission to kill Yeonsangun.
To achieve her goal, Dan Hee cast aside all hesitation and mastered intimate skills. However, her plan took an unexpected turn when she fell in love with Im Sung Jae.
The Treacherous paints a bleak picture of Joseon, a time ruled by fear and corruption. Amid the darkness, love flickers like a faint light, but will this romance overcome fate and find happiness?
Star-Studded Cast of The Treacherous
The adult film The Treacherous features some of Korea’s most renowned actors. The three leading stars are Ju Ji Hoon, Kim Kang Woo, and Lim Ji Yeon.
Ju Ji Hoon
Ju Ji Hoon plays the male lead Im Sung Jae, a powerful official favored by the emperor. His character is complex, harboring dangerous feelings for Dan Hee and hiding a secret agenda. With Ju Ji Hoon’s well-established acting skills, this challenging role suits him perfectly.
A decade after The Treacherous premiered, Ju Ji Hoon continues to be a leading actor in K-entertainment. Recently, he impressed audiences with hits like Blood Free, Light Shop, and most notably The Trauma Code: Heroes on Call, earning Best Actor in Television at the 2025 Baeksang Awards.
In 2026, Ju Ji Hoon is set for a major comeback in the blockbuster The Remarried Empress, starring alongside Shin Min Ah, Lee Jong Suk, and Lee Se Young.
Kim Kang Woo
Kim Kang Woo portrays the cruel King Yeonsangun. At 47, his chilling performance brings the tyrant’s brutality to life, evoking strong reactions from viewers. For an actor playing a villain, this is a major achievement.
Currently, Kim Kang Woo remains active in the industry. In 2024, he starred in two TV dramas, Wonderful World (with Kim Nam Joo, Cha Eun Woo, Im Se Mi) and The Tyrant (with Cha Seung Won, Kim Seon Ho).
Although he has no major roles announced for 2025, fans can look forward to his return in the historical drama Great King Munmu on KBS.
Lim Ji Yeon
The Treacherous helped earn Lim Ji Yeon the title “Queen of Erotic Scenes” from the media. Playing Dan Hee, she stunned audiences with her stunning looks, seductive figure, and scenes that seemed to set the screen on fire.
Today, Lim Ji Yeon is recognized not just for steamy scenes but as a talented actress. She has delivered powerful performances in The Killing Vote, The Tale of Lady Ok, Lies Hidden in My Garden, and especially The Glory.
