The last week what Oviya did cannot be accepted as it is. It is not the same character that we seen in the previous week. And I don't think Arrav is nominating Oviya just for Bindhu. Some people are supporting Oviya blindly which is not correct. With Julie, Oviya intended to hurt Julie which is not right no matter what Julie did for Oviya in the past. Similarly, in case of Raiza, she (Oviya) should not have mentioned the names in public where other contestants and Kamal are there though it was already recorded when Raiza said the story. At the end, Oviya asked Raiza why does she come to the show when she cannot accept these personal things. Personal is always personal. It is the case in any family between any family members.
Bindhu will be very careful since she already know the response from social media for Oviya.
