Angeletta is the granddaughter of the "Ice Queen," Countess Isabella Montovani. Her father, Count Adolfo Montovani, was the only son of the countess, while her mother, Giovanna, was a commoner. Both of her parents died without being personally recognized by her. When Angeletta was still a baby, she was entrusted by Lady Isabella to Marchelo Rossi. She was not accepted by her grandmother to that time.

Angeletta was raised by her foster parents, Marchelo and Edda. Unlike her foster parents' real child, Anzelmo, she is an extremely kind person. Angeletta is also great in drawing and writing journals. It was proven through her sketchbook and diary. She is suffering from a serious heart illness for a long time.

Romeo and Angeletta became very close friends. Angeletta was nicknamed by Romeo as his "Angel." Romeo and the rest of the Black Brothers helped the "Angel" to get accepted by her grandmother. They successfully convinced the "Ice Queen" that Angeletta is not after the Montovani estate. Countess Montovani then took custody of her granddaughter. She brought Angeletta to Paris to be treated for her heart illness. Romeo and Angeletta had already developed feelings for each other before they separated.

Angeletta is named "Angelita" in the Tagalog dub.
