@ASHA2012 I completely agree with you that both Dev and Sonakshi made mistakes which resulted in their break-up, in fact just like we need two hands to clap similarly a relationship depends on both the individuals, it's success or failure depends on both, no two ways about it.
Now I might be wrong but the main point here is that While we have seen that both Dev and Sonakshi have made mistakes yet time and again it has been only Dev who has acknowledged those mistakes, asked for forgiveness and tried to rectify it but can that be said for Sonakshi, at least in my opinion its a no. And I guess for quite a few of us that has been her biggest flaw, to own up on her mistakes. Yes you might feel that we are prejudiced towards Dev and that's probably because we are able to see his efforts in acknowledging and rectifying those mistakes which at least I cannot see with the BOSES and that's my biggest gripe.
Now coming to the show being about different shades of Dev, I agree that's been the case but more often than not these shades have shown his mistakes, in no track he was shown to be MAHAAN but what it did indirectly is show Sonakshi as the all knowing person and MAHAAN.
Just my POV, no offence.
