I strongly strongly feel that all four of them are at fault and are not saints.
Raj- He ignored his wife for 10 long years (I mean freaking 10 years), then wanted to marry Divya, then falls for Sarita who gets married to Vikrant and now wants her back. And he goes and gets engaged to Divya (I mean using Divya like this is not done even though she is no good either. See below). Can it get more insane and twisted?
Divya- She is NO SAINT at all. She had family obligations and ended up giving preference to her career over her love. That's okay. You can't really blame her for that. BUT, listen now. She expected that Raj would wait for her for 10 years when they never were in touch with each other. I mean, ARE you KIDDING me lady? Isn't that crazy and ridiculous? And when she came back to Bhopal, she wanted answers. She disappeared and now when Raj proposed to her, she never thought WHY now? Why all of a sudden?
Vikrant- Forget about his arrogance. I don't even want to go there and take that off the table for now. The very fact that he made a marriage deal is outright DISGUSTING. He is just very judgmental in my opinion. He is shown to be a smart businessman but he cannot see through Vandana and her family's evil game even though he knows how they are.
Sarita- I initially had sympathy for her and I think I still do. But, it has only declined over time. I mean she was ignored by her husband and ill-treated by her in-laws extremely badly who, by the way, I think are not fit to be part of a civilized society. But, it is just mind boggling that a woman would tolerate such nonsense for 10 LONG YEARS. Now that she is married to an extremely egotistical guy who has ZERO faith in her, why doesn't she sit down with both Vikrant and Raj and clear everything once and for all? No, but if she does that, the show will end.
What a horrible quagmire of a plot and a show.
I have ZERO sympathy for these four. just my POV.
