Bohot sochte hai!
and everywhere people are pissed off by Saudamini's character and that actress (cannot explain here why) and has been requesting to cut off this character or at least tone it down! But neither PH nor channel is hearing out to fans and are taking them lightly.
This is the heights of disregarding the viewers! They very well know no one wants to see the effing face of Saudamini along with Aniruddh especially when Bondita isn't attending. They're clearly promoting what they want.
You are taking it in an extreme way. Think it like, Only Saudamini was free from the cast lot. Also, she's at the moment, second lead of sorts. If not Bondita, she comes second in that list of important characters. So they invited her. They are not promoting her in that way. No channel/PH promotes the vamp/villain of the show as someone opposite any of the lead character.
