I remember in naamkaran the actress who played the role of Neil's ex said that her character was positive and she was excited to play the role of a positive character for first time. But nk fans didn't believe her. They kept on posting in social media that the character is just acting to be positive but she has hidden intentions and what not. The CVS thought that fans want to see the character as negative and so they changed the story and made her negative. Moral of the story- CVS get influenced by fans' views about the characters and mould them accordingly even if previously it wasn't in their plan
