Without a doubt, Choi Hyun is a devoted son, having tried everything in his power to help his parents who are afflicted by a mysterious illness. Despite the village’s most esteemed doctor being unable to provide a remedy, Hyun ventures into the mountains in search of the “guardian tree” as advised by the local shaman. Upon locating the tree, he discovers the presence of the mythical being known as the Kirin, or Tak-myung. While Kirin possesses the power to heal Hyun’s parents, it demands a favor in return. Although Hyun is prepared to strike a deal, darker forces are lurking, coveting the Kirin and its legendary abilities.
