The plot I remember is about, a famous shaman (Bottom) who has a guardian genie / khodam of an ancient Korean war general, who always tells the truth when serving his clients. However, one situation made this shaman unable to contain his Yin energy, so he was often attacked or molested by the surrounding ghosts. Then, this shaman accidentally did something that made himself possessed by the demon Incubus. The shaman's Yin energy made his body hot and desperately wanted to have sex with someone, so the guardian genie / chodam could not do anything. This Incubus demon influenced the Shaman until the Shaman (bottom) met a man (his Top) who came from the shaman's clan house(?), this man was like a young master in the place he was in, this man also had quite a lot of Yang energy, but this man could control his own Yang energy. This man helps the shaman (bottom) by having sex when necessary. And the two of them tried to exterminate the Incubus demon together.
