Suman!
Wow...you handled such a intricate array of emotions here- ranging from Sameer's disturbed bonding with his step-father to a step-mother that Naina would have been to Ahaana!
So Shefali is just a caretaker here...as I suspected (but does she have a major role in this story is for us to see).
Also, I'm thinking about the song you put in and somehow it resonates with Ahana's past...you did not tell us who Ahana's biological mother is and why Sameer doesn't even want to look at her.
I've a weird idea that Ahana might actually be Sameer and Sunaina's daughter. That makes Sunaina's betrayal all the more tragic and maybe gives a reason for Sameer's aversion to her. Well just a conjecture at this point. Perhaps she is indeed Rohan's daughter and Sameer doesn't like her for he sees the woman (her mother in her) the one who broke his brother's heart. But the song of paraye and dil ke rishte has me thinking.
Coming to Sameer and Mr. Somani's bonding- Sameer's words and the way Mr. Somani's hands found his was their solace. How circumstances change relationships right? Now Sameer is his only son whether he likes it or not.
The dream that Naina had about Ahaana and Rohan and Shefali- wow! That was very poignant. Ahana was on the verge of having a happy family- of having her mother and father close by and this dream was snatched away from her. Naina's resolve about taking care of Ahana with or without Sameer was heart touching. She has no bonding with Ahana, yet she is determined to give her the love of a mother- fulfill the promise she made to Rohan. That instant where she has to let go of Rohan and he falls and instead clutches Ahana was epic! Such wonderful symbolism lady!
All in all, a fantastic update! I'm eager for more- master of mystery! ;)
Loads of love,
