It need not take many episodes but at least it would be our choice.
I for one would like Naina to find Raghav badly hurt in a hospital and stand by his side while he recovers.
Take your pick of any of your villains( you had so many ) who try to attack them and Raghav saves Naina and Chotu.
Cut to Austria backdrop and the happy couple with baby Daadi and friends on vacation.
