When Shinhu Ki, the youngest prince of the Underworld, was tasked with guiding 30,000 spirits to the land of the dead, he figured it would be a breeze. Three years later, he’s barely made any progress until he meets Hajoon Yeon, who not only seems to be a lure for the spirits but is also full of yin, the source of Shinhu’s power. In exchange for helping Hajoon’s sick mother, the two enter into a contract where Shinhu can harvest that power anytime, anywhere he wants. And he wants a lot of it…

“If you give me your yin qi, I’ll listen to anything.” Shin-hu, who was punished by having to send 30,000 dead to the underworld and was kicked out of this world, while absorbing only weak yin energy in this world and unable to demonstrate his power, was drawn to a place where he was drawn to a strong sexual qi and encountered it like a coincidence.
He meets Ha Joon. They form a contractual relationship that requires each other, but gradually a strange current flows between the two.
