My take - think it is DV character that is causing this and lot of credit goes to CV's
Who would not be affected by feeling of first love .. DV when he came to panchgani was a carefree happy go lucky guy with a sense of humor (his earlier interaction with Saachi). Then he seems her struggling with family and responsibility and is in awe of her , I think that's where he starts calling her aap naturally .. then one fine day he realizes that friendship is taking a new turn and he is completely smitten by her ( fuse ud gaya ..) all this was handled so delicately by CV's that along with DV we were also falling in love. DV gave us glimpses of what first love is/ refreshed our memories.
Indian TV serials stories are made up of people who don't use logic when making decisions, sacrificing heroines, bitchy MIL and heroes who are either illiterate poor or head of corporate world in 3 piece suits( no consideration of age , some are barely out of collage). We may like them but we don't identify with them. The biggest USP of DV is that he is someone we can relate to , person with educated modern outlook , does not bother too much on society restricting norms that restricts out thinking, respects and loves his elders (does not mean you have to agree with them all the time), does not want to give up at first sight of trouble, is committed and his conscious is clear, no doubts . He is very different than the heroes we are used to in TV world .
Saachi on the other hand is like a lot of out TV serial heroines , sacrificing thinking about her family and not herself. If you remember during the confession days we did talk about her a lot as she was breaking out of her would and finally accepting her love for a younger boy. Then we again went ga ga over her after the proposal scene where she seemed to have developed wings . If she had stood up for her love then who knows we might have been talking about her , but her character sketch does not allow that . Also story needs some drama , and this made us sympathies/gush more with DV. I am sure the CV's will bring in a track where love/passion and commitment for DV will be in forefront .. Like DV said Saachi wala love
Then somewhere along the way we started connecting DV and Ruslaan . Ruslaan seemed to be an extension of DV, in the after take as well as old interviews Ruslaan seemed so like DV , modern, clear, confident and humble. He speaking style is also similar to DV which . His being on twitter /facebook admitting that he visits IF makes him like us. Forum being mostly girls and Ruslaan enduring good looks (he had a body to go along with it too) is a big plus. Even the guys like him because they want to gushed about like DV.
Refreshing change is always welcomed right .. like summer rain , makes the usual stressful world so beautiful
Too long post .. I think I am done for today J
