She's shocked and worried when she's sent away to marry Asran Hycariel, the son of a powerful yet infamously cruel ducal family. But to her surprise, she soon learns that none of the rumors are true, and everyone there is nothing but kind. And strangely, Asran seems to have known her since a long time ago...
