"With the loss of its physical body, the torn soul of the dragon became an imoogi, but even so it harbored a deep resentment against the Heavens, and this is our sin, as well as our doom, being the ones who devoured the dragon's flesh." Mu Yeon is deeply in love with his foster father, a courtesan, but the latter was taken over by the imoogi, Baek Sa. Despite Mu Yeon's hatred towards Baek Sa, who intends to use his foster father to ascend to Heaven, Mu Yeon finds himself unable to thoughtlessly harm his foster father's physical body. As Mu Yeon thus watches over his father, he realizes that Baek Sa is slowly assimilating his foster father's memories... "Shall I save you?" "Kill me, if you're not going to let me reunite with Father."
