Jungkook is a devil and Taehyung is an angel. These two go to school together after the leaders of the sanctums decide to make peace amongst the sanctums. We have the Devils, Angels, Zagans, Witches and the Nephilium, which are half-devil, half-angel. Can these two boys find a way past their differences? Even though there is peace, each leader of a sanctum sends in someone to watch over their kind, a spy of sorts, to be there in case peace is disrupted. However, two people find themselves falling for someone that is part of another sanctum will their love survive?
