Totally agree with you sonali.
And yes ppiyu asking Prithvi to choose between Delhi and herself is 'Pyaar ka Sauda'. Instead she could have asked him why he came to kill her father. And really Prithvi is too understanding, he didn't ask her one question. Really so sweet of him, even after knowing she is Sanyogita his enemy's daughter he still love her.(And she told him "Sach janne ke baad tum hamse baat bhi nahi karoonge Prithvi") But what's wrong with this Sanyogita.😡 after he confesses his love for her she is putting conditions before him.
