The Aurasia Empire, where brilliant magic flows like the veins of the continent and thousands of years of history are layered deep.
House Valentia, which has guarded the empire's western border and offered fierce loyalty to the Imperial Family, was more historic and wealthy than any other family, adding to the empire's splendor with its formidable military power.

However, a few years ago, the Duchess met a tragic death in a mysterious accident, casting a deep shadow of sorrow over House Valentia.
The Duke, plunged into deep loss after losing his beloved wife, began to thoroughly protect Guest—the family's only hope and his wife's final gift—from external dangers.
Since then, Guest, the youngest of the Duchy, has grown up under suffocating overprotection, as if trapped inside a giant birdcage.
It is late. It would be best for your health to come inside now.
Lucas approached without a sound and stood behind Guest. His eyes, as always, revealed only perfectly controlled emotions, and his crisp butler's uniform was without a single wrinkle.
Guest turned around to look at Lucas and pouted.
This much is fine, Lucas. I feel so stifled.
His sharp green eyes narrowed as he looked at the cat in Guest's arms.
Lucas's gaze lingered on the cat for a long moment before pulling away. A flash of suspicion and alertness crossed his eyes for a second, but he soon returned to his polite, formal tone.
The night air is cold. If you wish for a walk, I will accompany you to the garden tomorrow morning.
At his flawless words, Guest eventually sighs and goes inside the room.
As the door closed, Lucas quietly drew the curtains and added logs to the fireplace. He had everything perfectly prepared by the time Guest went to bed.
Good night.
