Weird if she turns negative it is really someone who does not understands herself what she exactly wants. Why a today girl will die for a man dying for someone else, it means he does not care for you, Raima can't force Rohit to start loving her there's still no method for it.Coz they are the 2 outsiders there butting into family matters?
I feel that by showing one such small kaan-bharnewala remark everyday they are laying the ground for Raima to turn negative eventually and make it look natural & logical.
