Felia, the youngest girl ever to become a magic tool craftsman in the royal palace, was living her days in constant suffering, trapped in a harsh workplace full of exploitation and mental pressure — forced to work even on her days off, with no rest or appreciation.

As if that wasn’t enough, she received another crushing blow when her fiancé broke off their engagement, shattering her heart and the only motivation she had left to keep going.

But amidst this despair, Felia meets Prince Julius, the second prince, who is suffering from a mysterious curse threatening his life.

Thanks to her rare genius, Felia manages to temporarily suppress his curse, and from that moment, her life begins to change completely.

The king decides to appoint her as the prince’s personal magic tool craftsman, pulling her away from the hellish job she had before — and so begins her new journey, searching for a way to break the prince’s curse and save him.
