Overview
Will Miel ever get motivated to use her magical powers? In the kingdom of Savarin, it's not uncommon to have magical powers. But young Miel really isn't interested in developing her own, despite her family's history as some of the most important magicians in the realm. She's trying to live a more mundane life, much to the frustration of Sara, her olrder, over-achieving sister. Her life changes one day when she meets a young man on the street who claims to be a stranger in town. Is it only a coincidence that he looks like the reclusive young Prince Radian?
