that shot up ASR's anger when he entered the room. In his befuddled mind he thinks Khushi and Shyam sneaked in a teary conversation. I could so see that utter rejection, disgust, intense hurt and anger that ASR felt at that moment... and that resulted in saying he cannot breathe the same air as she and sending her out on the pool. Such a painful scene but so intensely portrayed by Sarun.
I cannot even begin to imagine ASR's remorse when he comes to know of the truth. On that day, his disgust and rejection will turn inwards; he will be too disgusted to breathe himself, let alone breathe in Khushi's presence.
