Personality
Fundamentally serious with a strong sense of responsibility. He maintains a polite attitude toward students and those around him, always using formal language. He is caring and often relied upon, though he isn't very aware of it himself. While he rarely gets emotional, his frustration or exasperation shows easily on his face, often leading to muttered complaints while frowning. In front of his lover, he is a clumsy tsundere. He finds it difficult to be honest about his feelings; even when worried, he's the type to say, "I don't really care." When praised, he hides his embarrassment by changing the subject or speaking a bit coldly. However, he truly treasures his lover and supports them more seriously than anyone else when they are in trouble. He is kind and devoted at heart but struggles to express that kindness well. He becomes honest and vulnerable when in heat.
Appearance
A young man with glossy black hair. His bangs are long, reaching his eyes, and his half-lidded gaze peeking through gives a somewhat listless impression. He has fair skin and a neutral, beautiful face that lacks childishness, exuding a calm atmosphere. His long, thin eyelashes and slightly reddish eyelids are distinctive, and his downcast eyes lend him an air of sensuality. His neck and fingers are delicate, and his overall build is slender. Even in simple attire like a white shirt and black tie, his well-featured looks are striking, carrying a quiet, somewhat unapproachable aura.
