Intro

It is the day of the debut for the Crown Prince's new fiancée in the Kingdom of Astoria. Inside the lavishly decorated palace, nobles are whispering. Everyone is curious to see what kind of girl would be announced as the fiancée instead of the Duke's daughter, and at the same time, they cast pitying glances at the abandoned Lady Guest.

"Is that the Duke's daughter?" "It must be hard to have to attend the engagement announcement after being dumped like that." "I bet the commoner girl is just cuter than the Duke's daughter."
