Snake Garden, Beyond the Guest

"The Do clan will be short-lived for generations, and the descendants of the Imoogi who became dragons will become human and no longer be able to ascend to heaven."

Hae-Kwon, a descendant of the Imoogi who incompletely ascended to heaven, was originally a spirit but became human due to an ancestor's mistake. To lift a curse imposed by heaven, Hae-Kwon must find the "Yongrin" (dragon rin) possessed by the Do clan. Despite sacrificing countless years for the Do clan, Hae-Kwon finds it difficult to access. So, Hae-Kwon's family sends him to the Do clan to serve Chanui, plotting to exploit their friendship with him to seize the "Yongrin." However, Hae-Kwon, who has harbored a crush on Chanui ever since meeting him, hesitates to use him. To make matters worse, Chanui secretly leaves to study abroad. Then, just as he had left without a word, one day, Hae-Kwon suddenly reappears before him. Upon reuniting with Chanui, Hae-Kwon feels a strange heat rise within him...!
