Why this drastic change, Yuvika?

Suddenly, the sweet smiling Yuvika is becoming rude, and argumentative, and using words like "nakli" etc for housemates 😲

Yesterday's episode was especially an eye opener - she was behaving and turning out to be just like Kishwar. I still have no clue why Kishwar and Yuvika pounced on Roch early morning when she was talking to Puneet. Also, agreed Mandana was brisk to begin with, but why stretch the issue so much Yuvika? If Mandana didnt want her bed to be cleaned or touched, just leave it, and move on to the next...

The sweet Yuvika, though looked fake, was heartwarming... Not this one. This one looks like Kishwar's student, and that too a topper 😡
