This story is turning like this due to ka+sa personal problem they have'nt any off screen good chemistry or you can say have not any healthy relation ship, or may be karan's arrogant and aggressive nature. I think creative don't want to turn kiran in to kasturi but sa+kp not wants work together, i think creative know this thing very well they will replace shubhagi this show will be suffer, if they will be turn kasturi in negative that will not good this show, I think they wants new guy's entry in this show (like mr. bajaj for prerana), I think shubhangi will be in this show but from Robbie, but creative is aware this thing if this will be happen it will not be accept by viewers, and they will carry on shubhangi and karan as well may be possible same situation will be create in future like lake of mutual understanding, lake of profession attitude so i think this show must be stop with happy ending not like this creative ruined all story of this serial. What do you think guys.
