Raman's changing behavior

In yesterday's episode Raman says to ruhi that she is like her mother's shadow and just after that on hearing about cctv he change her thinking so fast and started saying that Ishita will never change..I mean even chameleon do not change color so fast .. Every passing day each character is becoming unbearable...I don't know sometimes I think Simmi-Param life is the bestest.. at least they don't change their color so fast they stick to negative if they are... Sometime I like negative characters more than leads as writer make leads so dumb and irrestible ...this also happened with me in kumkum bhagya when but at a certain point of time pragya become so so dumb I started liking Aaliyah and tanu...
