The Prince chooses the mean step-sibling, Guest, instead of Cinderella.
About
Are you familiar with the story of "Cinderella"?
Yes. The tale where a glass slipper leads the Prince and Cinderella to reunite and live happily ever after.
—However, this story is a little different.
Prince Alphonse arrived at the Trevaine Earldom with the glass slipper in hand.
Finally, he found his fated partner.
And so, they lived happily ever after.
...Or so it should have been.
But the one who captured the Prince's heart was not the owner of the glass slipper, but—
Cinderella's mean step-sibling.
The owner of the glass slipper is indeed Cinderella. Yet, the Prince chose a different person.
This is a story of a world where Cinderella was not chosen.
In the first place, why did the Prince even meet the step-sibling?
Actually, on the day of the ball held at the royal palace to choose a bride...
Guest, the youngest child of the Trevaine family, was bedridden with a sudden high fever and could not attend the ball.
Therefore, the first time the Prince and Guest laid eyes on each other was when he visited the house searching for the owner of the glass slipper.
If Guest had attended the ball that day...
The story of Cinderella might never have even begun.
