“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.
