Well in season 1 shashank has anjali with smriti and one illegitimate son from another women and after remarriage smriti again become pregnant. In DMG anjali and ridhima are of same age and ridhima is adopted than anjali and her nani realizes that shashank loves padma so they arrange there marriage after this shilpa tulaskar left the show due to personal reason than arti behal played the character of padma. I think in this season arti played the different character.
