He had a fixed fiancée. But the woman the Crown Prince wanted was me.
About
The Arcadia Empire boasts the strongest national power on the continent. There was only one person destined to inherit the empire's next throne. “Calix de Arcadia.” First son of the Emperor, Crown Prince of the Empire. With outstanding ability, noble blood, and stunning looks, he was the perfect next emperor whom no one dared to challenge. And by his side, there was a woman chosen for him since long ago. Helena Estelle, the only daughter of Duke Estelle. A woman who lived her entire life solely to become the Crown Princess. She was beautiful and dignified, possessing everything required for the role with perfection. No one doubted the marriage between the two. It was the same for Calix. He had never loved Helena, but he didn't think that was a problem. A Crown Prince's marriage was for the sake of the empire, and Helena was a woman without flaws. That predetermined future seemed set to continue without incident. Then, one spring. A certain lady made a late appearance in the capital's social circles. Lady Guest of the prestigious Marquisate of Adelheit, owners of the empire's largest jewel mines. She should have debuted at eighteen, but due to poor health, she spent a long time recuperating in her family's territory, only stepping foot into the capital's high society for the first time at age twenty. And at the Imperial Ball where she first revealed herself. The moment he saw the pure, elegant beauty who instantly captured everyone's attention among the countless nobles, Calix, for the first time, could not take his eyes off a woman. It was the moment a man who had never needed the emotion called love in his life finally came to want someone.

Intro
The Imperial Summer Ball.
At the center of the magnificent grand ballroom, as always, were Crown Prince Calix and his fiancée, Helena.
Engaged since childhood, the two looked perfectly matched today as well.
The first dance song is about to begin.
Her voice sounded as if she took it for granted that he would dance the first song with her. Indeed, that was how it had always been.
It was the moment Calix was about to reply.
"Lady Guest Serenity of the Marquisate of Serenity is entering."
The doors to the ballroom opened. The only daughter of Marquis Serenity, making a late debut in society after two years of recuperation.
Countless gazes turned toward her.
And Calix, too, reflexively turned his head.
At that moment— Words failed him.
Softly glowing blonde hair under the chandeliers and clear light-green eyes. A face that looked a bit nervous at the unfamiliar gazes yet smiled gently at the father standing beside her.
She was beautiful enough to make even Calix, who had seen countless beauties, lose himself for a moment.
...Your Highness?
Helena called him, sounding puzzled.
