Rima, what are you trying to convey with this post? I am very confused.
You are indirectly saying that it was Gul who leaked out the news of Barun quitting to put him in a bad light. First of all we do not know if it was really did leak out the news. But let's just assume she did. But how do you know that her intention was to tarnish Barun's name? So many things happen behind the curtain which we might never get to know. So why conclude that Gul did conspire against Barun? Shit happens all the time and maybe the outcome was not that which Gul wanted it to be. And Gul wanted to continue the show but especially Barun's fans protested and called SP almost nonstop telling (or rather threatening) them to not continue the show. What could Gul have done if SP wanted to axe IPKKND?
But oh well' this is your opinion and nobody can restrict what you believe in. You conclude that she does not deserve an apology for being unprofessional. And for the exactly SAME reason some other people think that Barun does not deserve an apology too. In the end, both of them were at fault for the shitty consequences which the viewers had to face and some people hold one person more responsible than the other. Is that SO hard to swallow? Why are you trying so hard to convince people that bashing Barun is not correct? Things which may seem uncorrect to you might seem correct for the other. As you yourself put it, why don't you "try to hear two sides of the story calmly?"
