That is the essence of the diff between Bani and Pia. Pia is focussed on getting what she wanted, Bani tries to keep everyone happy and ends up mucking up everything.
Bani dancesvery good to but because she was more focused on finding AK and also thinking about her sister pia that shes happy but not her sister and she had promised her dad thet she will make a good life for her sisters so thats why pia was better.
