What if..

Wishful thinking? Oh most definitely. Itni achhi kismat ni hai hum sabki. Aaj tak jo sab predict kiya galat nikla. Their misunderstandings are only increasing with every episode starting with Suman making Shravan meet Nirmala back then. Wonder when will we see a silver lining amidst all the drama. Shayad letter is the solution. Usse thoda kam ho from Shravan's side. Atleast the hatred. It's OK if the misunderstandings take their time to clear then. It'll become bearable. They need to be able to talk civilly atleast before we can expect an open dialogue between them.

But this could also be a good filler where one episode is wasted in him finding the letter, the other in his reaction, his remorse. Then a third where he starts to hope and goes to meet sumo. Then another where Aditya tells sumo what Shravan said before leaving(or maybe later). This would make a week full of filler episodes. And they won't even seem filler! Viewers will actually be happy.
