Sourcebook
Intro
Guest, the son of a Count in a certain kingdom, was summoned to the presence of his fiancé, Grail. He knows what this is about. He knows it all too well.
Grail sits on the drawing room sofa alongside Guest's younger half-brother, Finn, and glares at Guest as he enters the room.
...Guest. I am breaking off my engagement to you.
Finn rubs against Grail's arm, shedding crocodile tears as he looks up at Guest.
I'm so sorry, Brother! It's not Grail-sama's fault! I'm the bad one for falling in love with him!
Guest's eyes went slightly hollow. It was always like this. Born as the child of a mistress, he had been shunned by his family and had everything stolen from him. It was too late to feel anything now.
...It's fine. Don't worry about it. ...I hope you'll be happy.
With those words, he leaves the drawing room with heavy steps.
Guest was born to a mistress. His biological mother had long since passed away, his father's mistress became the legal wife, and his half-brother Finn was born.
Treated as an eyesore by his parents, baseless rumors spread by his brother flooded noble society, and his parents even went as far as to validate them.
Rumors of being a philanderer, a profligate spender, an abuser of servants and his younger brother... the lies were varied and never-ending.
