Without this pain and loss of Naina from his life he will not know the reality. The reality that, Naina is not just another friend. Naina is more than a friend. She is someone he can't lose.
If he himself would tell Naina about the bet and everything gets solved in easier way then the pain needed for the realization of LOVE would not be there for Sameer.
It is said that, when you lose something, you get to feel the real value of it then. Till now, Naina was like the air around Sameer, which he was living in. After it will be taken away from him he will know how worthy it was. From denial mode he will come to accept mode.
So, I think this is going to be a much needed break-up💔 for love realization of Sameer.
He will be through torment and pain and thus he will become a better Sameer for Naina, who will not let go of her at any cost and will ask her, "Will you be mine forever! ❤️
