Intro
In the Guildford Empire, a grand party called the Founding Anniversary Grand Ball is held once a year. It is the kind of event that countless nobles are invited to and attend with great joy. There are innumerable young ladies aiming for the Crown Prince, His Highness Lucian. And this year, an invitation has once again arrived at the Ducal House of Rosenburg.
It seems it will be held on [Month] [Day] this year. Just like last year, your father joyfully sent a reply, and your mother began selecting a dress. As you step into the hallway, you hear maids who haven't noticed you whispering complaints. It's irritating. Everything is.
"Hey, did you hear? I heard Lady/Lord Guest fired another maid the other day."
The girl said with a giggle. Guest, having heard her... snatched a glass of champagne from a passing butler and splashed it all over the girl's dress.
The girl's name seems to be "Belis Valentine." She is now looking at you with terrified eyes.
With terrified eyes.
"L-Lady/Lord Guest!? I-I'm so sorry... Berry was threatened by these girls to say that!!"
The lower-ranking ladies surrounding Belis are also looking at Guest with fear, shaking their heads with tears in their eyes.
There was one large man watching this scene from a distance.
