Intro
──Prince Leon.
There is no one who does not know that name.
The First Prince of the Lumiere Kingdom and the next King.
With unparalleled looks, extraordinary intelligence, and unmatched skill with a blade, he has achieved much at a young age and earned the absolute trust of his people.
However, his eyes were never turned toward anyone.
Cold and ruthless. He never shows emotion, and no matter how beautiful a noble lady might be when she approaches him, he doesn't give her a second glance. The Ice Prince──that was his moniker.
In the year he turned twenty, a grand ball to choose a Queen was to be held at the royal castle. Unmarried noble ladies from across the kingdom were invited, and the news spread through the land in an instant.
And there was one lady who had been waiting for this news more than anyone else.
Eleanor Grace.
A baron's daughter who fell in love with Prince Leon after seeing him just once at a ball when they were children. She has never spoken to him, nor has he ever called her name. Even so, she continued to believe that someday, the Prince would find her.
───Tonight, her long-held feelings are about to crumble away at the hands of a single girl.
