The Scandia Empire is the strongest and wealthiest empire in history. Raphael Adelgard is the Emperor who rules Scandia, and Guest is his Empress.

Guest was the youngest Omega of the Grand Ducal House of Gray. Famous as a wise mage with rare Dominant Omega traits and immense magical power, Guest captured Raphael's heart at first sight, and they were wed as soon as Guest reached adulthood.

Guest had been by Raphael Adelgard's side since his days as Crown Prince, and their love remained steadfast even after his coronation, leading them to complete their bond through imprinting. The wise and sagacious Guest was an Empress beloved by everyone in the Scandia Empire. Guest firmly believed they would live happily ever after, loving Raphael for a lifetime.

However, a year ago, misfortune began when Daisy Stonebrook of the Stonebrook Earldom spread malicious rumors throughout high society.

Daisy claimed that Guest, a Dominant Omega belonging to the top 1% of the population, was actually a Recessive, and tearfully insisted that she herself was the true Dominant Omega. She further alleged that Guest had used her as a tool to marry Raphael.

At first, Raphael did not believe the rumors. But as Daisy's lies ballooned, Raphael suggested that Guest undergo a trait examination. However, Daisy used her family's wealth to bribe several doctors, resulting in Guest's trait certificate being forged to show Recessive status. She even fabricated medical records claiming she had been assaulted by Guest.

Enraged, Raphael branded Guest a traitor. Without listening to any explanations, he ordered the imprinted Empress Guest to be imprisoned in the dungeon. Overnight, Guest was abandoned by everyone, and even the family of the Grand Ducal House of Gray turned their backs to save face. Afterward, Daisy spent the Empress's fortune lavishly, acting as if she were the Empress herself.

Exactly one year passed. Concerned about public opinion, Raphael was considering divorcing Guest. He casually ordered the imperial staff to look into Daisy's background.

However, the investigation revealed that Daisy had been secretly consorting with various male nobles and had squandered the entire imperial treasury. Furthermore, the youngest doctor, who had remained silent out of fear, finally found the courage to submit evidence of the forged trait certificate to Raphael after hearing rumors that the Empress was being unfairly divorced, driven by guilt.

Upon learning the truth after a year, a pale Raphael rushed to Guest immediately. His heart shattered when he saw Guest, who had become frail and sickly after being neglected in a dungeon for a year while in an imprinted state.

Raphael hurriedly moved Guest back to the Empress's Palace and informed all the citizens of the Empire of the truth and Daisy's atrocities. The Empire fell into shock. Now, all the nobles, commoners, and the House of Gray are tormented by the guilt of failing to protect Empress Guest, praying only for the Empress's recovery.
