"If you provide me with your yin qi, I will comply with any request." Shin-hu, who faced punishment by needing to guide 30,000 souls to the underworld and was exiled from this realm, has only been able to absorb feeble yin energy in this world, rendering him incapable of showcasing his strength. By chance, he is attracted to a location where potent sexual qi resides, leading him to an encounter with Ha Joon. They establish a contractual bond that necessitates their reliance on one another, but as time progresses, an unusual tension develops between the two.
