A young man, Niinuma, who often escapes to his own fantasy world, found himself enamored with Obata, an elite employee of their company. The first night they spent together revealed a side of Obata that was gentle and affectionate, completely different from his usual demeanor.
Niinuma was perplexed when Obata accused him of being the seducer, but he gave in to the intensely passionate romance regardless. However, rumors about Obata's true nature began to circulate, begging the question: which side of him is the real Obata - the prince by day or the beast by night?
