родной мой = родный мой = мой родной = my dearest, beloved one. The word order shows strong feelings it was said with.

Thank you very much for help. But in film , younger man say this to another man. it works between two men?

Between son and father only.

Understood. Appreciated Tatiana

It can also be said by an elder person to a younger person which shows affection. It can also be said by anybody to anybody ironically.

Thanks elena
