juhi has a reason towards her behavior.
she is trying to become close to kiya bt kiya always give her attitude like The Kiya Gujaral.
remember there first conversation like " I am aquarius and you r nothing "
kiya always behaved wid her like a celebrity.
bt juhi is always seen caring towards kiya. in group she always protected her bt kiya always insulted juhi.
she not behaved like friend wid juhi.
so it is excepted tht one day juhi go against her.
.
remember everyone having ego of themselves .
if kiya having her ego then juhi also have her ego.
.
bt one gud thing for kiya is Bobby looking to become softer to kiya .
