a poll with all kzk couples - /forum/kasauti-zindagi-ki/770942/cutest-jodi
Again these poll were during the middle of the show. Overall and from beginning and in the end Anupre were the most loved. Most shows have such phases. And even here the comments are mostly for Anupre and two of these polls aren’t even about which couple is most loved. So why these links? One is about whom should Sneha be with and one is which couple will end together in the end which we all know which couple ended up together! Only two of these poll is about which couple is liked. I was never active in that forum, but just looked on the surface the polls and majority there were Anupre fans and that too I just checked the end show posts and end pages.
