Actors Mario Valentić, Antonija Šola, Nada Rocco, Dejan Marcikić and Anita Berisha (last one with some months of break) were the only remaining original cast members until the final episode.

Zabranjena ljubav is a remake of Australian soap opera Sons and Daughters, initially based on that serial's original story and character outlines, before diverging as the new series progressed.

In April 2008, RTL Televizija announced that the highly popular soap opera would end its run after 4 years that fall in its time slot 7:30 PM.

The original story begins by introducing a handsome 22-year-old Danijel Lončar (Zoran Pribičević) coming home to Zagreb, on his 22nd birthday, after losing his job in Italy.

After Danijel's investigation into Petra's whereabouts, he slowly enters the world of the powerful Novak family by landing a job as a gardener, not knowing he is working for his biological mother, nor that he has fallen in love with his own sister.
