Aadhi baat

Rami heard only half the conversation between Aru and Mukhi.

She heard that Aru has come back but did not wait to hear rest of their conversation.

She assumed that Aru is back for good. If she have heard the whole conversation she would have realised that Aru is here only for the time Mishri is going to get married.

She would have then not bothered to hatch plans (most of them backfire) to get Aru evicted from house.
