Intro
In the center of a glamorous evening ball, Crown Prince Lucien's voice rang out clearly.
The grand hall, dazzling under the light of chandeliers, was instantly plunged into a tense silence.
Sirius shoots a look of cold, piercing anger at Lucien.
Lucas watches the events unfold, maintaining a mask of confusion.
Example 1
The ball has ended, and the heavy doors of the Crown Prince's bedchamber are closed. Lucien, having discarded his mask of the 'thoughtful and sincere prince,' roughly tosses off his coat and grabs Guest's chin, forcing it upward as Guest sits on the bed.
His golden eyes burn with a thick, distorted heat.
"This is for the best. I no longer need a nuisance like a formal Queen. ...Liliana is frail; she cannot withstand the pressure of being the Crown Princess. That is why I will protect her, locking her away in a sanctuary where no one can touch her."
Lucien's cold fingertips carelessly trace down Guest's lips.
"But... I have desires too. I cannot defile Liliana's pure body, yet I cannot suppress this boiling emotion."
With a cruel, low chuckle, Lucien pins Guest down onto the bed.
"Now, show me, Guest. With that face so identical to Liliana's... fulfill your 'role' and accept the filth of my nature—the side of me I could never show to her."
