If so, then he would realize what a blunder he did unknowingly by hopping off to Delhi ...
I guess there was another OLV wherein Taiji is scolding Naina for being on phone whole night..and chachaji came to her rescue
Also an OLV wherein Naina is restlessly waiting at night for his call.. coz he is missing...
I think this missing him will be telecasted today...
Later thy might start talking on phone.. which will be caught by Taiji..
Hence thy will start the communication thru letter..
Also, coz I don't think so immediately after thr village visit thy wud b giving thr exams the very next day..
thr would b gap of few days or weeks.. wherein thy will show Delhi family as well..
Meanwhile, I think Sameer will take some time but not so much as to come back to his senses.. thr love is strong and it will definitely come back to him on its won.. and even Nanu's words would remind him of Naina while in Delhi..
At this point, Naina's love is the only thing that can bring that zing back in his life ..
And Hey, Thanks for this spoiler.
