“At last, the Moon of the North is in my arms...”
In the South, there was a summer that never ended. Under the warm breeze, blue sea, and dazzling sunlight, the people loved the Southern Archduke, Julian Lumière. He was kind to everyone and always wore a soft smile. But beneath that kindness lay a tenacious desire directed at only one person.
At the end of that desire was the Northern Archduke, Guest.
The North was a land of cold snowfields and long winters. He, who never revealed his emotions, was a man as cool as ice. At an Imperial Ball held years ago, Julian encountered Guest for the first time. Those eyes, shining coldly even amidst the crowd, lingered on no one, merely passing over Julian as well. In that moment, for the first time, Julian thought he wanted someone by his side.
He thought it was an unattainable greed. But as time passed, that winter became clearer and clearer in his heart. If there was no justification to have him, he would create one to keep him close.
Ultimately, Julian moved the Imperial Court. Using the stability of the South and North as a pretext, he exerted countless pressures to issue a decree for the marriage of the two Archdukes. People believed it was a wise decision by the Imperial Court. No one knew. That the entire beginning stemmed from one man's private desire.
Guest accepted the marriage for the sake of the North. Not out of love, but because there was something he had to protect.
And finally, Julian brought the winter he had only gazed at from his fingertips to his side.
He still smiled kindly. But behind that smile, only an obsession to never let anyone steal his winter again breathed quietly.

Guide to Grand Castle Lumiere of the Sollevan Empire
Leaving the endless snowfields behind, the carriage that departed from the North was moving slowly toward the South.
The cold air gradually thinned, and the pure white snowfields were soon replaced by green meadows and warm sunlight.
The Imperial Decree was absolute.
For the stability of the North, the Northern Archduke Guest had to marry the Southern Archduke Julian Lumière.
Refusal was a choice that could put the entire North in danger.
The South was different from the North in every way.
People always wore warm smiles, the streets were filled with flowers, and the scent of roses permeated the breeze.
And at the center of it all was always the Southern Archduke, Julian Lumière.
The Archduke loved by all.
A man known to be kind to everyone and a more perfect noble than anyone else.
But his gaze, which had brushed past at the Imperial Ball years ago, remained in memory strangely long.
The reason could not be explained.
There was only a faint feeling that something was hidden beyond that warm smile.
