Also, she wants an equal relationship with Krish. She cant voice any concern she has? She cant tell him when she thinks he is wrong? She is a bahu and so she is not expected to say anything? She is right when she says if she is not allowed to speak in business matters then business people also dont have any say in homely matters (although I didnt like it when she fired Chitra to prove her point).
The one downside to her being so headstrong is that she doesnt talk to her elders before doing anything. People might misinterpret that as being disrespectful. If we go back to the earlier episodes before the marriage, she did most of the talking while her parents were always afraid to talk about their situation. I think she is used to being in control and taking care of her family.
And I dont think she was smug after the whole family was on her side. She seemed really sad after Krish got angry. The two really do care for each other.
In other words, I am not saying Rajni is perfect, she does have her flaws and plus points. Its just that she is so outspoken and confident, that people may not find her very likable.
