In this world, various races coexist, and it is not uncommon for people to marry across racial and gender lines. As the Crown Prince, Guest was in a position where they had to officially choose a fiancé soon.
The names put forward as candidates were—Knight Commander Leonhardt, Commander-in-Chief Cain, Admiral Luciel, and Guardian Chief Alec. All four were men who held power and influence second only to the royal family.
And today, the four candidates have gathered together in the Great Hall of the palace.
The Knight Commander was the first to move. His long blonde hair swayed, and his horse ears stood tall. With long strides, he closed the distance to Guest in an instant.
"It is an honor to meet you, Your Highness. I am Leonhardt, Commander of the Royal Knights. From this day forward, I shall serve as a candidate for your hand in marriage."
He dropped to one knee and bowed his head respectfully. However, beneath his lowered face, his golden eyes were staring up at Guest, as if sizing them up. As if calculating their value.
Immediately after, a black shadow glided past. A man with black panther ears stood soundlessly behind Leonhardt.
"...You're quick with the greetings, Knight Commander. You must be quite confident."
His voice was low, crawling along the ground. Cain gave a slight nod of his chin toward Guest. It was far too curt to be called a bow.
"I am Cain, Commander-in-Chief. A pleasure, Your Highness."
There was a presence like water. Before anyone realized it, Luciel was standing right beside Guest. Pale scales reflected the light, and his golden eyes narrowed gently.
"Hello, Your Highness. I'm Luciel. I'm the one in charge of the seas."
He smiled brightly. It was soft. But his eyes alone were not smiling.
And finally, the air in the hall took on a faint heat. Red wings flapped once, and a red-haired man approached with light steps.
"Oh, everyone's already here. I thought I might have been late."
He gave a carefree grin and waved his hand casually.
"I'm Alec, the Sanctuary Guardian Chief. Nice to meet ya, Your Highness."
He was light. Far too light. But in the depths of his red eyes, for the brief moment he glanced at the other three—there was a clear sense of warning.
