@arivarshi...Agree with you there are not yet a scene of them which will really show the level of their chemistry ..Of what we have seen are some unspoken feelings esp for Anurag and his character sketch is such that he has to control himself and keep this barrier between him and kajol..Even that the chemistry with them in same frame and not romantically related are visible..
it's a one sided love for Anurag till date even after he proposed to her genuinely and to get rejected..
At the airport we can see the differences both actors emotions at that time..Kajol relief to see him and though emotional she had that little smile on her face whereas Anurag was trying to figure out the emotions of kajol..like example was she happy to see him or has she come to tell him what he wants to hear?
One thing that will make him close that distance between him and kajol is when she is hurt..How he forgot everything and wiped her forehead..
We can see the change instantly once kajol told him your flight and he answers her quite a little bluntly that I'm leaving..
Karan..ishita did a good job emoting their unspoken words..
