She is an introverted and thin girl, but she has a mysterious personality charm. She was born in Italy, the child of a nobleman who had an affair with his sister. She was trafficked to Germany when she was very young, and lived a life of hunger, cold and displacement. Her father later lived on the streets, playing the piano for a living, and was later taken in by William Meister. Since I met the bachelor, the fan Niang has lived the best and happiest life and has fallen in love with the bachelor strongly. However, due to illness, she died soon.
