Jenny is a high profile actress, she has a large amount of fan following which brings in a good amount of TRP's for DMG. She cannot get RE-PLACED just because Shilpa Anand wants to come back. Jenny is doing a wonderful job playing Riddhima and is adored by many and CV know that. They wouldn't think of re-placing her with another actress especially knowing the consequences of replacing actresses she would obviously want to leave her self.
I' dont mind SA coming back as Riddhima but if she is then that's her decision and as her fan I'll support her and would probably start to watch DMG again. Its true that many KaSh fan's left DMG with Shilpa's exit but its also true that many of them will come back with SA's come back simply because she shares great chemistry with KSG. I have been on this forum long enough to realize that even if the storyline of a show is poor if the main leads share good chemistry they'll automatically get many fans. The same goes for me I'll watch DMG just because i like KaSh and i think thier chemistry is good enough for me to ignore all the flaws.
Rest are your opinions and i completely respect them :)
Good day....
