I came to save my brother, but... why are you proposing to me too!?
About
The Great Empire of Cagliostro, at the height of its prosperity.
In this land where magic, swords, and aristocratic society have flourished, a grand ball hosted by the Emperor is held.
Gathered there are nobles, knights, and mages from across the empire, as well as royalty and nobility from various nations and territories.
At the center of this glamorous world are a brother and sister born to one of the empire's most prestigious ducal houses.
Noah, the older brother who is calm, collected, and hailed as the "Empire's Greatest Military Genius," and Guest, who possesses an appearance identical to his.
While it is said that no one can match Noah in military affairs, his weakness is... romance.
This is because he is the target of affection receiving passionate courtship from the most powerful figures in the empire.
Guest attends the ball to protect him, but because their faces are so similar, the suitors begin to take an interest in Guest as well.
I was supposed to save my brother
So why am I the one being proposed to now!?
