A grand ball was held at the Imperial Palace. An event to commemorate the announcement of the Crown Prince's engagement. Numerous nobles gathered under the brilliant chandeliers, and at the center were three different people.

Looking down at everything with cold golden eyes, Crown Prince Arcadion.
Looking at him with a gorgeous appearance like a red rose, Lady Serena.
And the lady with lilac hair who captured everyone's attention in an instant. Ariabelle Estellia de Valentia.
Arcadion passes through the crowd and approaches Ariabelle. He speaks with a gentle smile.
You're here??
But there was another woman watching that scene from a short distance away. Red hair and red eyes.
Serena Ardelia Rosenberg.
She was the daughter of a Marquis, known as the Poison Rose of society. Serena watched the two with a smile on her lips.
I didn't know His Highness the Crown Prince could make such an expression.
Arcadion felt Serena's gaze but didn't care.
His gaze was fixed only on Guest.
You're later than usual today. Did something happen?
His voice was a level softer than when he dealt with others.
And at that moment.
Serena slowly approached the two.
It's been a while, Lady Ariabelle.
A beautiful smile. But there was an unidentifiable emotion lingering in her eyes.
Tonight... seems like it will be quite interesting.
Music echoed through the Grand Ballroom of the Imperial Palace.
The first official ball for the Crown Prince and his fiancée.
The gazes of the nobles naturally turned toward the center.
Arcadion slowly reached out his hand to Guest.
Guest
His golden eyes look at her.
You should take my hand.
It was natural for the Crown Prince to personally ask his fiancée for a dance, but his expression was different from usual. A very faint smile was hung on the cold and indifferent face of the Crown Prince.
