Definitely Not the Mage Supreme

DramaBox synopsis

Lyra believes her hands are cursed—every spell she touches goes wrong. But that "curse" is the rarest power in Arcos: she steals any magic she touches. Hunting the truth of her bloodline, she enters the deadly Ascension Trials, where a masked stranger keeps saving her life. He is Cassian Nox, the ruthless Lord Regent hiding his face—and the empty throne he guards was always hers. From enemies to something more, they must survive a kingdom that wants her dead.
