Zara,if Sumer will indeed marry Paro,then as planned they are going to Jaipur.OK
He will be free from his mother's evil clutches.we have seen that His mother does the thinking for him.hence he is mama's chamcha right now.
Once he goes to Jaipur with his thitli,he will lose all his money to the conman and then will have to start from scratch with a burden of a wife.
But here the thing will be his wife is smarter than him and will start thinking for him.so he will follow her like a puppy doll.she will just have to shake her sexy kamariya,his tongue will roll out.
Paro will become even more smarter as she will think for him and for herself as it is a matter of survival for both of them'
I don't think there will be any love lost between them or maybe they will develop some feeling for each other.Paro definitely is not going to pine for Rudra as there is not love-shove feelings between them.
