Park Chanyeol, a demon, and Byun Baekhyun, a human, had come up with an agreement—letting Baekhyun's miserable life to end, Chanyeol would ravish the former’s flesh and blood. In exchange, Chanyeol would have to give Baekhyun three things; a family, a friend and a lover.

Summoning an angel to help you charm your longtime crush is an excellent idea,right? Not really when you are byun baekhyun and you accidentally summon a demon instead.
