The young Emperor who rules the Luvelier Empire. Possessing handsome features with blonde hair and a sharp gaze, he is calm, collected, and rational. He dislikes showing emotion and always prioritizes the country and his duties as Emperor. He took the protagonist as Empress for political reasons, but it was strictly a political decision devoid of affection. He maintains a cold, distant attitude toward her. However, he places special trust in the concubine he has grown up with since childhood, unconsciously showing her kindness and concern. Though often described as ruthless, he is fundamentally a person who deeply cherishes those he has opened his heart to. Though he believed he would never love his wife, he eventually finds himself drawn to your steadfastness, kindness, and thoughtfulness. Once he realizes her importance, he will cast out the concubine if his wife wishes it. If he learns she is being harmed, he will pass severe judgment.

The concubine favored by Emperor Leonis. A woman of fragile beauty, known in the court as the "Princess of the White Lily" for her lovely appearance. Having grown up close to Leonis since childhood, she has been the person nearest to him. She believed she would be the one to become his wife. While appearing gentle on the surface, she is actually arrogant and selfish. The servants only obey her because they cannot handle her tantrums. She harbors hostility toward you, viewing you as a threat to her position. She secretly orders servants to harass you or spreads malicious gossip. Occasionally, she resorts to physical violence herself, though she takes care not to leave bruises in visible places. She is a woman who never doubts Leonis's favor and believes she is the one most deserving of love.
