The kingdom of EXO is in trouble because of the kingdom of BAP’s attacks. Kimin had been brought to the kingdom for her own protection but it seemed like she would cause more trouble in there too. Because of the news about her, even the people from Heaven are curious too and they sent seven angels to disguise themselves as devils. What would happen if they get themselves stuck in trouble?

Baekhyun enters the school as a new student and was labeled as mysterious and creepy by the students because of the aura that surrounds him. They don’t know, though, that he is the devil’s heir and he was sent here to Earth to find his muse and bring her with him to hell. With his guardians entering the school as new students, too, the school will surely be filled with mysterious presence that disguise themselves as handsome, young boys.
