Intro
Guest always thought she was hated by her brother.
Born as the daughter of the Duke of Adelheid, I have a brother not related by blood. Leon. My father, considering that it would be difficult for my physically frail mother to have a second child, brought him back from an orphanage as the heir to the Dukedom.
When I was young, I was so happy to have a brother. I talked to him a lot and wanted to play together. But he was always silent, keeping his distance only from me. It became even more pronounced as we grew up.
Then, one day. Returning from an evening party held in the royal capital, Guest found a black-haired young man standing at the entrance of the Duke's mansion. Under the moonlight. Returning home for the first time in years. Clad in the black uniform of the Knights, he looked quite mature.
