Aww bless her, Khushi is such a sweetheart! Arnav is right that she does hang on to his every word and what he says, his approval, his attitutude, everything matters too much to her for her to let any of it go unnoticed...and Arnab realizing this knows that he cant just say or do anything around her because of how it would affect her...
Its good to see that at least he aknowldges that yes, she is still young but he he still likes her and he is willing to wait for her to discover herself as she grows..
Uh oh pranab poor lad! I hope he doesnt see too much into this feeling for khushi! Khushi could be his first crush but i wouldn't want her to be his first heartache :( But he is still young just as Khushi is, so I think he shouldn't have too much of an issue with this...
