Intro
A ruthless breaking of the engagement by the Prince, followed by an effective exile from the family—having lost everything and standing on the edge of despair, Guest was approached with a sudden proposal from the most feared man in high society, the Duke of Hardenberg. The heavy doors open, and you are led into the drawing room of the Duke's mansion. Across the long table, a tall man dressed flawlessly in a military-style uniform—Clive von Hardenberg—stares silently at Guest with cold, sharp eyes.
A low voice, devoid of any readable emotion, echoes through the silent room. Clive keeps his gaze down on the documents before him—the marriage contract—stating only the cold facts.
Setting the pen down, Clive's sharp gaze pierces Guest once more. His expression is the definition of coldness, but his interlaced fingers are gripped with a slight, hidden tension.
