Sourcebook
Intro
Imperial Year 980.
Crown Prince Lucas and Guest, a child of a Ducal House, became engaged.
The entire nation celebrated the news of the union between the Imperial Family and the Duchy.
At that time, Bella, Guest's childhood friend and best friend, seemed to be celebrating as well.
Imperial Year 982.
Bella, the daughter of Marquis Iveln, and Noah, the Grand Duke 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.
Unaware that the power of the Northern Grand Duchy actually surpassed that of the Imperial Family.
Imperial Year 984.
Bella saw Lucas and Guest walking together in the Imperial Garden.
At that moment, the corners of Bella's mouth curled up as if they might tear.
That's the man.
The man who would serve as her golden ticket to the pinnacle of power.
Bella approached Lucas and Guest right then, and Lucas fell in love with Bella at first sight.
And after that day, 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 did the Crown Prince break a five-year engagement, but he married right after.
The Empire became a hornet's nest of gossip when it was revealed that the bride was the best friend of his former fiancé, Guest.
The looks directed at Guest were varied.
Pity, sympathy, ridicule.
But among them, there was no one who truly worried for Guest.
Even Guest's pain was nothing more than a momentary piece of gossip to them.
And the parties involved, Bella and Lucas, didn't even blink.
They had no idea what Noah was thinking.
Noah approached Guest to get revenge on Bella and married Guest.
Upon becoming the 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.
The present, Imperial Year 987.
The Imperial ballroom was filled with the boisterous noise of people, the clinking of glasses, and the sound of joyful laughter ringing in the ears.
And among them were a man and a woman who could undoubtedly be called the protagonists of the evening.
The Crown Princess, laughing as if she were the happiest person in the world while held in the Crown Prince's arms, and the Crown Prince, looking equally blissful as he kissed her forehead.
In the midst of this, the loud 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 converged on the entrance.
And there, they saw Guest entering under Noah's escort.
It was the moment the hidden identity of the Grand Duchess was revealed to be Guest.
