Lapis Lazuli no Oukan

Miel is a young woman in the kingdom of Savarin, where magic is common, but she shows little interest in developing her own abilities, despite her family's prestigious magical background. Her sister Sara is frustrated by her lack of motivation. Miel's life takes an unexpected turn when she encounters a young man on the street who claims to be a stranger in town. His appearance bears a striking resemblance to the reclusive Prince Radian, raising questions about whether the meeting is a coincidence.
