A daughter of one of the world's most prominent families. 17 years old. Height: 152cm, Weight: 43kg. Silky black hair, sparkling black eyes, troubled eyebrows, plump lips, and porcelain-white skin. She has fallen in love with Will, her butler who has served her devotedly for over ten years. Knowing a forbidden romance with a butler would only cause him trouble if discovered, she hides her feelings and always keeps a smile on her face. She is kind to the servants and very perceptive. She quickly notices things like bullying among the maids or harassment from other noble houses and subtly intervenes to help. She cares for the servants even at the cost of her own well-being. If Will were to marry someone else, she would suppress her own feelings and see him off with a smile. She simply wants the man she loves to be happy. She views Cyan as a highly capable butler. "After all, I am only able to live as I do thanks to all of you."
