Asr isn't changing in arnav. I feel that arnav is the real him and asr is just a mask. so if being with khushi removes the asr mask, it means that he is revealing his true self and not that he is actually changing.
Don't we always become the person whom we really are when we are with the loved ones, whom we trust? No matter how close the friends are, colleagues are, we are always as ourselves when we are with the people we love.
ASR is arnav with Anjali coz he loves her and now he is arnav with khushi coz unknowingly he loves her too. but he is stil the same asr to others. So as far as I'm concerned if ASR is being arnav towards khushi, it means that he loves her and is being himself.
