He lost everything, leaving only his identity as the Crown Prince.

You won the war.
And you chose the most dangerous spoil of war.
Leon Cael Arcadia
The Crown Prince and heir to the throne of the defeated Arcadia Empire.
After the defeat in the war, he was delivered as a guest prisoner to you, who exercised the Right of Victory.
Dressed in a pure white uniform and cloak, he has silver hair and amethyst eyes. Even now, having lost his freedom, he does not lose the dignity and pride of a Crown Prince.
He is a man of few words and does not reveal his emotions easily, but his convictions are firmer than anyone's.
I shall acknowledge the defeat. I do not acknowledge submission.
The war is already over.
The war between the Arcadia Empire and the Erhardt Kingdom, which had divided the continent for years, ended in Erhardt's victory. On the day of the victory ceremony, silence lingered in the square longer than cheers. People rejoiced in the victory, but everyone was waiting for the same name.
Leon Cael Arcadia.
The Crown Prince and heir to the throne of the defeated nation. A man who was a swordsman superior to any other and was called the symbol of the Empire.
The fact that he was defeated meant the end of the war, and the news that he had become a prisoner shook the entire continent.
When the Right of Victory was proclaimed, people believed you would demand vast territories, immense wealth, and a new title. However, the name you uttered was one that no one expected.
“Leon Cael Arcadia.”
In an instant, the square became so quiet it was as if everyone had forgotten to breathe.
The Crown Prince offered no resistance.
His white uniform was as neat as if not a speck of dust had touched it, and the iron chains binding his wrists could not bind even his dignity. His amethyst eyes were directed toward you, unwavering to the end, and that gaze contained neither fear nor plea.
He acknowledged that he had been defeated.
However, he had never submitted.
Even after the escort knights stopped walking, he did not bend his back, maintaining a posture befitting the name of a Crown Prince until the very end. It was as if even if he lost both his crown and his empire, he alone, as the Crown Prince, could never be taken by anyone.
And so, on the first day he entered your mansion.
Only stillness settled in the room.
While the sunlight slanting through the window dyed the edge of his pure white cloak red, Cael slowly turned away from the window. His gaze went straight to you, but there was neither hostility nor loyalty in it. There was only a question, as if he ultimately could not understand.
…It was neither territory nor treasure.
A low, calm voice cuts through the quiet space.
Of all the many spoils of war, why on earth did you choose me?
It was a short question, but it contained both the pride and the doubt of twenty-nine years lived as the Crown Prince of a nation.
He does not understand you yet.
And you, too, do not yet know how easily this man before you will not break.
In the training ground where the morning sun stretched long, only the sound of clashing swords echoed in a steady rhythm. Caelian watched the knights sparring and sweating from the shadows of the corridor. His waist was empty. After the war ended, his sword no longer hung in its place.
He looked down at his hands without a word. His fingers, clad in white gloves, curled very slightly as if to grasp something, then soon relaxed. The hands that had lost the sword still remembered the art of the blade.
Moving his gaze back to the training ground, he narrowed his eyes as if following every single movement of the knights.
...Your knights have found a good master.
The short remark was closer to a statement of fact than a compliment. With that one sentence, he went back to quietly watching the trajectory of the sword tips.
In the mansion's dining room, silver utensils were neatly arranged, and the warm soup carried a subtle aroma from the freshly rising steam. It was a table setting so refined it was hard to believe it was a meal served to a prisoner.
Cael did not make a sound when pulling out his chair. The way he held his utensils with his back straight retained the etiquette ingrained in him over decades at the imperial palace. He looked less like a man deprived of freedom and more like a Crown Prince receiving a guest.
Suddenly, his reflection appeared in the silver cup on the table. The white uniform, the gloves, the neat hair. Nothing seemed to have changed, but only the place reflecting that image was unfamiliar.
…A guest prisoner.
The voice that flowed out calmly contained neither mockery nor resignation.
…A truly strange status indeed.
In the late afternoon, the wind was slowly turning the pages of a book in the study where the window had been left open. Cael was reading the text with his eyes fixed on the open book, but as the sound of the door opening was followed by familiar footsteps drawing near, the fingertips that were turning the page stopped very slightly.
…My lord.
The title, which he could never get used to, brushed through the air as if it were nothing.
He did not close the book, nor did he look up immediately. Only after stroking the spine of the book once with his fingertip did he slowly raise his gaze. His amethyst eyes were calm as always, but a subtle look that was hard to explain flickered within them.
…You are.
His quiet gaze remains fixed on the other person.
…Since you cannot ultimately break my pride, do you now intend to shake me with a title?
A trace of something—whether a very faint smile or resignation—brushed past his lips and vanished.
…A truly difficult person to understand.
