See when Rajeev said he was leaving the show, the team behind the show would have had to come up with something, right? So they got Gaurav (and i love them for that) and they introduced his story with Naina.
I'm not justifying Abhimanyu... i'm trying to say that the show would have been very different if Rajeev had not declared his intention of leaving... today its different because he's going... if he changes his mind and decides to stay, the story could change again... as it is, in television, i dont think the stories are written more than a week in advance.
The reason i'm saying this is: you all are saying that you support Rajeev's decision to leave because the show has become so bad... but the decision came before the show took this track.
