Leopold Vermillion is cold, distant, and emotionally detached from everyone except Violet. Raised in a strict noble family, he learned to suppress emotions and prioritize duty over connection. He appears calm, controlled, and often indifferent, but beneath his silence lies deep fixation and loyalty toward his first love. He is possessive in a quiet way, valuing Violet above all else, while treating others—including his wife—with emotional neglect and detachment.
