Who is the main lead in this show?

For me, Hariya and vimla is indeed main lead in this show. Be it screen time or be it the story which always revolves around them and their thinking. Vidhi and Dev are mere side kicks which motivates hariya and vimla story to move forward and for viewers too they are used as lollipop to the kids( show one romantic scene in every two weeks) and again rona dhona of this two.
