Actually I want this to be happened... Naina confronts Daksh:
Naina: You got a lot of time to express your love... but you were silent. Now tell me what will I do? What should I say to Abhi and what about Sonakshi? how much they will hurt??? [pauses.. thinks and with a lot pain and regret with tears].. no... no.. I don't want to marry anybody leaving you... (cries) I can't lose you... nobody should love me other than you... [stops crying, wiping her tears, by managing her mind and shows her bold face] No... I have to stop this mrg however... sometimes, hearing this all will feel bad.. they will be upset and hurt but... i think they will understand us..
Daksh: No Naina, that will make many problems between the families.. so lets go ahead with the mrgs...
[with pain both goes down for the mrg...]
Then Moushi will find out Naina's past and the mrg gets broken off.
But I think what is going to be happened...
Before Naina reveals her feelings, pain, love (before concluding their confrontation) they are called as the time of mrg is getting over... both will be indifferent and ready for mrg... but the mrg will be broken up... Naina shows a bold face after that. After going home Sonakshi will tell her mamma that Naina Bharadwaj's mrg mess up incident. hearing that Supriya will shocked (may be hearing her surname) she will come to confirm her doubt and finds that she is the mother of Naina. Knowing the truth Naina will understand that Sonakshi is her half-sister and she will not tell her true feelings to Daksh. Daksh will misundertand that Naina is not at all happy in knowing he loves her. And she does not love him. And plan to go ahead with Sonakshi eventhough he canot love her. thus Daksh will become the KP again... and very arrogant... Naina understands what happens to Daksh... Daksh can tell his true feelings to anybody only after he drank rite? may be another drunken day he will reveal Sonakshi that he does not love her but he loves Naina... but Naina closed eyes towards him etc.. When Daksh is spoiling his life in this manner, Naina cannot bear and she forced to express her love... she will tell that she loves him very much...
[what I mean, it will take more time Naina express her love... we have to wait more for that I feel]
