Arre. I don't see it, but you could make your idea work, but with a twist! If they grew-up sibling-like, but realized their feelings later, then it'll work, na? Like Pragya could be an orphan, but Daadi adopts her or something along those lines...
omg i love this kind of story - well i love the the version where the guy (abhi) would realize after years of treating the girl (pragya) as "that annoyance i just have to put up with" - wait, she's a girl? wait, she's not my girl? wait she's going to go off and get married to someone else -no.
sorry...i know it's...well...whatever it is...but i like it :P
