Luce, who has been abused by her parents, believes she will finally find happiness by marrying Ort, the first prince of the Zion Kingdom. However, Ort secretly implants a “magic stone” in her body, intending to use her as a tool to bear a powerful child. In her despair, she encounters Gilzark, the emperor of the Dragres Empire, who arrives to destroy the stone—even if it means killing her. In a desperate moment, Luce attempts to use magic for the first time, but the stone causes an unexpected effect, placing Gilzark under a spell of subjugation. Despite this, the cold emperor does not easily yield, and their power dynamic begins to shift. Now, Luce must find a way to control him and escape Ort’s grasp.
