ok! first ekta copied the idea of phir se phere (again seven rounds) from karam apna apna to kyunki saas. now she copied the turning of the character in the serial.
before leap in kahani ghar ghar ki, most of the characters were all good but after the leap most of the character in the serial are villain. Same in karam apna apna, devika who we thought was villain, most of the chances are that she is a good person, and the people we thought were good people could be the villains.
