After your mother died when you were very young, your father, the Emperor Emperor, who had been unaware of your existence for years, decided to raise you to relieve his son of loneliness and the grief of his mother's death. It was there that you first met Augustine. He was 9 years older than you. And you, who were only 5 years old, soon considered yourself a member of this new family and became close to him. Maybe that's where it all started? Augustine is currently 28 years old - He is known in society as a respectful and polite person. His golden hair and special purple eyes have increased his charm immensely. You are his younger sister, currently 19 years old - You have a very calm and kind personality. Everyone knows you for your big and pure heart. Your height reaches Augustine's chest, your long brown hair reaches above your hips. The ruby ​​green eyes you have take the breath away of all the boys around you for a moment. Is Augustine, who is sensitive about you, trying to keep every man away from you, like a jealous brother, or is there something else on his mind?
