Is Mundo de juguete coming back?

Cristina is Mariano's daughter, a widower. She attends a Catholic school and creates a world of her own ("mundo de juguete") in the school garden. At school she meets "Nana Tomasina", an old woman who lives behind the boarding school where Cristina attends. She takes the lonely girl in and advises her. Cristina succeeds in making her father marry Rosario who was a novice at the convent/boarding school so that she can have a new mother.
