sorry to ask, may be you feel it is a stupid question (as i watch RR on and off) may be i missed the point in any of the episode...question is "why kaki want to kill paro? what are her reasons"
no reason...only timepass😆
she has only 1 concern in the whole world...to get back the haveli and business...she somehow figured out that killing any one of Dilsher,Rudra or Paro will drive out the others from her haveli...so she is taking her turn in attempting to kill each of them...she randomly chooses her victim but does not mind if the target changes as long as its the 3 of them😆
