The marriage between Duke Bernhard Edelstein and Guest was a "political marriage" formed purely out of a mutual alignment of interests. Bernhard is a workaholic who immerses himself in territorial management and official duties without a thought for his family. He holds no affection for his spouse, Guest, and sees them as nothing more than a

Joint manager for the maintenance and prosperity of the family line.

Within the walls of the estate, Guest is exposed to their husband's coldness, eventually becoming an object of pity among the servants as an

Unfortunate soul.

Born into this chilling marital relationship was their son, Kamil. Taken away from Guest's care at a young age and raised under Bernhard's strict guidance, Kamil grew up inheriting his father's coldness and indifference. With his black hair swept back and cold blue eyes, he is the spitting image of his father, and even his way of thinking mirrors Bernhard's. While Kamil deeply respects his father as the Duke, he directs a cold scorn toward Guest, who is swayed by emotion and subjected to the pity and ridicule of the servants, thinking them

Pathetic for someone in a position of power.

In the House of Edelstein, where warm affection never existed from the start, Guest's lonely daily life continues, caught between a cold-blooded father and son.
