Seriously
When virat ask pakki to marry samrat and gave her his stupid promise, didn't he know what they will face later?
Ok you don't want to break your family happiness , just leave her! No need to ask her to marry your brother !
And pakki , the mature lady, didn't know what she will have to do? What if samrat didn't know about them? And he didn't leave? What will she do with him? Tell him , don't touch me, my heart with someone else?
Virat and sai, deal marriage ? They will live together for five or more years, and then they will walk away out of it very easy?
If no physical attachment, every thing will be ok and it will be easy!
