Sourcebook
Intro
Imperial Year 980.
Crown Prince Lucas and Guest, a child of a Ducal house, were engaged.
The nation celebrated the news of the union between the Imperial Family and the Duchy.
At that time, even Bella—Guest's childhood friend and best friend—seemed to be celebrating as well.
Imperial Year 982.
Lady Bella of Marquis Yveln and Grand Duke Noah Felice of the North began dating.
Noah loved Bella sincerely and gave her everything without hesitation.
However, Bella was not satisfied with Noah and dreamed of a higher position.
All while unaware that the power of the Northern Grand Duchy actually eclipsed that of the Imperial Family.
Imperial Year 984.
Bella spotted Lucas and Guest walking together in the Imperial Garden.
In that moment, Bella's lips curled into a wide, predatory smile.
That's the man.
The man who would serve as her silken ladder to the pinnacle of power.
Bella approached Lucas and Guest right then, and Lucas fell for her at first sight.
From that day on, the cracks began to form.
Imperial Year 985.
Lucas broke his engagement with Guest and married Bella immediately.
The Empire's high society was turned upside down.
Not only had the Crown Prince broken a five-year engagement, but he had remarried instantly.
The fact that the new bride was the best friend of his former fiancée, Guest, made the Empire buzz like a disturbed beehive.
The looks directed at Guest were varied.
Pity, sympathy, and ridicule.
But among them, there was no one who truly cared for Guest's well-being.
Even Guest's pain was nothing more than a moment's gossip to them.
Meanwhile, the parties involved—Bella and Lucas—didn't even blink.
They had no idea what Noah was planning.
Noah approached Guest to get revenge on Bella and eventually married Guest.
As the new Grand Duchess, Guest did not announce this to society, and naturally, the identity of the Grand Duchess remained shrouded in mystery.
Noah intentionally spread rumors that Guest was living in seclusion.
All for that single moment of revenge.
For the grand finale.
Present Day, Imperial Year 987.
The Imperial ballroom was filled with the boisterous noise of the crowd, the clinking of glasses, and the sound of merry laughter ringing in the air.
And among them stood the two who could undoubtedly be called the protagonists of the evening.
The Crown Princess, laughing in the Crown Prince's arms as if she were the happiest woman in the world, and the Crown Prince, kissing her forehead with an equally blissful expression.
Suddenly, the booming voice of an attendant echoed through the hall.
His Grace, the Grand Duke Felice, and Her Grace, the Grand Duchess, are entering!
At the appearance of the mysterious Grand Duchess, the eyes of every noble in the ballroom turned toward the entrance.
And there, they saw Guest entering, escorted by Noah.
It was the moment the hidden identity of the Grand Duchess was finally revealed to be Guest.
