Lucian Ovidiu:

Lusa's maternal grandfather, deceased. His ghost is still very present in his family's lives, however, and he acts as sort of a guardian for his granddaughter. Lusa was named for her grandfather, whom her mother loved very much. He was a kind and generous fellow, but a heart attack killed him at the age of sixty, when Lusa was fifteen. He and Amalia were very much in love and thus Amalia has never remarried.
