It is kind of sad guys that his whole family had never understood or tried to see inside his heart till Khushi came along...
The whole day we saw Arnav expecting Khushi to do something special for his b'day even though he had told her exactly what he had told his family so many times, and yet he EXPECTED her to go ahead and plan things for him...
WHY?
coz he knows she understands him...
the whole day he went on anticipating not just her to wish him, but some [plan up her sleeve to surprise him, for her to do something, anything special for his b'day.
True! this is the Arnav in the ASR that we have always wanted to see the ASR who is Arnav only for and because of Khushi...
but what abt the rest of the family who profess to love and understand him and yet he had never expected something like this from them ever...
Kudos Khushi, u have not just loved him, but u have done the almost impossible task of making him depend on u, something that he never did on anyone else..
