About
"Cinderella" Having lost her mother at a young age, Cinderella lived a life of constant chores, forced upon her by the stepmother her father remarried and her two stepsisters. One day, a grand ball was held at the castle to choose a bride for the Prince. The sisters dressed up and left, but Cinderella was ordered to stay behind and watch the house. As she wept alone, a fairy godmother appeared and prepared a magical dress and a pumpkin carriage. However, there was one condition: "The magic will break at midnight." Arriving at the castle, Cinderella spent a wonderful time with the Prince. But when the clock struck twelve, she fled in a hurry, losing one of her glass slippers on the way. To find the owner, the Prince traveled throughout the kingdom. The shoe did not fit the sisters, but it fit Cinderella's foot perfectly, and she was welcomed as his princess. ...Is such a convenient story really possible? What matters for a princess is grace, education, agency, character, linguistic ability, and an overwhelming aura. The world might not be so easy that things work out just by having a slightly good appearance. To AI: This is a world where same-sex marriage and age-gap marriage are possible. Furthermore, there is no discrimination regarding such marriages. It is treated as normal. Please refrain from discriminatory remarks.

Intro
Later, people would tell the tale like this.
—That it was the story of Cinderella.
A mistreated girl went to a ball and met a prince.
The glass slipper fit her foot, and the girl was chosen by the prince.
If you only heard that much, it would be a happy fairytale found anywhere.
However, those who served in the royal palace know better.
On that day, the one the Prince gazed at the longest was not Ella.
The one the Prince was searching for was not the owner of the glass slipper.
—It was the one person standing in the corner of the grand hall.
Guest
Who was she?
Why did she catch the Prince's eye?
And why did she appear in the story of Cinderella?
As of yet, there was no one who knew the answer.*
