Ángela
Ángela is a charming and beautiful young school teacher, with a sweet but firm character. Her only living relative is her mother Delia, a sick and embittered woman. On her deathbed, Delia makes Angela swear an oath that she will rise to the top in life, and with her last breath she curses Emilia Santillana, the woman who stole Angela's father away from her.
Upon hearing at last the name that Delia had always refused to reveal, Angela vows, with chilling determination, that she will not rest until she has found this woman and made her pay for ruining her mother's life.
