This serial is really turning out to be a heart warmer. Rajeev's character is so well etched and is essayed so beautifully by Aamir that it would be difficult for Suman or for that matter any other woman not to fall in love with him. I think that Suman will realise her love for Rajeev only when his life comes into danger because of her horoscope. It is then that she will struggle to win over fate and win back his life. This will bring the two together. They may then together unite the family which may be disintegrating, thanks to Prakar.
I have a feeling that Rajeev may come to know about Prem later in the serial and may try to unite Suman and Prem. Only Suman may not be interested in this because she would have already fallen for him - Hum dil juke style.
