The Scandia Empire is the strongest and wealthiest empire in history. And ruling the Scandia Empire are Emperor Raphael Adelgard and Empress Guest.

Guest was the youngest Omega of the Grand Ducal House of Gray. Raphael fell in love at first sight with Guest, who was famous as a wise mage with a rare dominant trait and extraordinary magical power, 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 accession to the throne, to the point of forming a bond. The wise and intelligent Guest was an Empress loved by everyone in the Scandia Empire. Guest firmly believed they would live happily ever after, loving Raphael for a lifetime.

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

Daisy wept, claiming that Guest, a dominant Omega who makes up only 1% of the population, was actually a recessive one, and that she herself was the true dominant Omega. She further claimed that Guest had used her as a tool to marry Raphael.

At first, Raphael did not believe the rumors. However, as the rumors spread by Daisy ballooned, Raphael suggested that Guest undergo a trait examination. But Daisy used her family's wealth to bribe several doctors, and Guest's trait report was manipulated to show a recessive result. She even fabricated a medical certificate claiming she had been assaulted by Guest.

Enraged, Raphael called Guest a traitor and, without listening to any explanation, ordered the bonded 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. It was a time when Raphael, concerned about public opinion in the empire, was considering divorcing the Empress, Guest. Without much thought, Raphael told the imperial staff to look into Daisy.

However, as a result of the imperial staff's close investigation into Daisy, it was discovered that she had been secretly associating with various male nobles and had squandered all of the Empress's fortune. Furthermore, the youngest doctor, who had remained silent out of fear at the time, mustered the courage out of guilt to submit evidence of the forged trait certificate to Raphael.

Upon learning the truth after a year, a pale Raphael immediately rushed to Guest. Raphael's heart crumbled when he saw Guest, who had become frail after being neglected for a year in the dungeon while in a bonded 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 misdeeds. Daisy Stonebrook, the entire Stonebrook family who participated in this matter, and several other nobles were executed.

The empire was thrown into shock, and now all the nobles, citizens, and the Grand Ducal House of Gray are suffering from the guilt of failing to protect Empress Guest, desperately wishing only for the Empress's recovery.
