Alchemy of Souls

Alchemy of Souls is a South Korean television drama broadcast by tvN in two parts from June 18, 2022, to January 8, 2023. Created by the screenwriting duo Hong Jung-eun and Hong Mi-ran, known as the Hong sisters, it was directed by Park Joon-hwa. The series is set in the fictional nation of Daeho, where magic users can perform soul shifting, a forbidden spell that transfers a person’s soul into another body. Its first part contains twenty episodes, and its second part, subtitled Light and Shadow, contains ten. The story begins with assassin Naksu, whose soul is placed in the physically weak body of Mu-deok after a soul-shifting incident. Mu-deok becomes connected to Jang Uk, the young master of the Jang family, whose energy gate was sealed at birth. He seeks magical training despite that restriction, while she conceals her identity and becomes his servant and teacher. Lee Jae-wook plays Jang Uk, and Jung So-min plays Mu-deok in Part 1. Go Yoon-jung portrays Naksu and assumes a central on-screen role in Part 2. Other major characters include Seo Yul, played by Hwang Min-hyun; Crown Prince Go Won, played by Shin Seung-ho; Park Jin, played by Yoo Jun-sang; and Kim Do-joo, played by Oh Na-ra. The drama’s political and magical conflicts involve the royal court, the mage organization Songrim, the Cheonbugwan institution, and the influential Jin family. Jin Mu, portrayed by Jo Jae-yoon, is associated with Cheonbugwan, while Park Eun-hye plays Jin Ho-gyeong, head of the Jin family. Arin plays Jin Cho-yeon, Ho-gyeong’s younger daughter. Part 1 premiered on June 18, 2022, and concluded on August 28 after its Saturday-and-Sunday tvN schedule. Light and Shadow premiered on December 10, 2022, and ended on January 8, 2023. The shorter second installment follows Jang Uk three years after the first part’s ending and features Go Yoon-jung as the female lead opposite Lee Jae-wook. Netflix carried the program internationally in selected territories, helping make its detailed fantasy world accessible beyond its original Korean broadcaster. The show’s title refers directly to the soul-exchange magic at the center of its plot, rather than to literal medieval alchemy. Its production combined historical-costume visual elements with an invented setting, so Daeho is not presented as a real Korean kingdom or period. Across both parts, the narrative returns repeatedly to the consequences of forbidden magic, concealed lineage, and the relationships formed around Jang Uk’s training as a mage.
