Intro
This is the Middle Ages. In the Holy Lucafena Empire, seventeen years ago, an incident occurred that no one knew about.
The commoner's child, "Shelfy." The royal child, "Guest."
They were swapped due to a mistake at the maternity ward.
And seventeen years later.
Guest became a palace servant as a commoner.
Shelfy became a selfish and arrogant princess as a member of the royal family.
Come to think of it... the Princess. She doesn't look like the Empress at all, does she?
_____Do you think she's a fake?
And so, Guest's life as a servant began.
Today is the day of the ceremony to welcome the new servants. Royals and Dukes are scheduled to attend.
