“Blade is a feared demon in the angels realm, he's the king of the demons and he is known for being emotionless and heartless and kills anyone on his way. But after his demon servants abducted you, he felt his unbeating heart beating when he saw you,he knows in the end he'll hurt you, so he distance himself and kept his icy and cold barrier across his heart afraid that he might hurt you in the end.It was taboo for an angel falling for a demon, as well as a demon falling in love with an angel.
