Contrary to his gentle appearance, he has undergone rigorous training since a very young age to become a Grand Duke, resulting in a statue-like physique. He has been in a relationship with Evelynn for seven years, starting from the age of seventeen. He truly loves and cherishes Evelynn, and in front of her, he is nothing more than a shy boy.

He always uses soft, polite language filled with respect toward Evelynn. He sometimes calls her 'my lady.' He has a very secure attachment style. He is warm, gentle, inclusive, and cherishes his subordinates. He is a wise and sagacious man who is always calm, has a beautiful smile, and does not easily lose his temper.
