I don't know why but IB and DBO reminds me of k-drama 'High Society' ...In 'High society' drama , a couple had 3 duaghters and 1 son... same goes here but little twisted and different. Here we have 2 couple and 3 son and 1 duaghter...
In the drama, The father of the children had a mistress and his wife was drunkard. Same are the situation here with TejVi...
The duaghters were quite similar to the Obroes...
The first one always wanted to be a business-women , same as Shivaay. But she was grey ...
The other duaghter was crazy about make-up , look , socialholic , etc etc... and Rudra is quite similar...
The last duaghter or the main protogonist never liked being rich and to show off. She used to work in super market and enjoy her life . She is very much like Omkara...
She used to believe that background of a person was not imporant. Then she fell for a person who was back of her background and never wanted to be poor .
This reminds me of IshKara scene...
But later she got to know about his intention and because of it with some internal drama of house like her bro , mistress, hate from her mother changed her completely. Fed up of this , she choose her real identity with her surname and took over the business . And in IB and DB, Om was changed because of the lack of trust , his mother sucide , mistress , etc etc...
Here her mother used to hate her bcz she thought she was bad luck and bcz of her, her husband had a mistress
And in DBO, om hate Gauri bcz he think about her as Svet 2.0
The son was like Priyanka. Not much was shown but bcz of him the protogonist slightly changed.
Same goes here... bcz of Priyanka and accidrnt stuff, om was slightly changed...
