Spoiler: Arzoo finds a letter

Sahir comes to know of Anam being Anu - the last person spoke to Zeenat before her accident. He tries to unravel her connection with Zeenat and also gets doubt on Vikram to be connected with Zeenat. Later in the track, Aarzoo gives Sahir a big surprise by presenting red baloons to celebrate Valentine's day. Sahir was not expecting such a thing but nonetheless both get another opportunity to come close. The twist comes with Aarzoo finding a revelation in terms of a letter about Zeenat. Will Aarzoo and Sahir come closer with that development or develop distance for some reason ?
