Infact , if you look at it , Asad's anger is directed towards his father and more than anger , its bitterness and a sentimental complain. Otherwise, Asad is well-mannered , perfect on etiquette , soft spoken , loving and generous. Even when Zoya almost rammned into his car , he didn't fly off the handle and thrash her . He was nice to her , concerned too and when she started her chappad-chappad, he still showed patience and respect keeping his volume low.
I don't know but i see Asad as only angst ridden and emotionally isolated for his own needs. Just my opinion.
