why dont you pick up sumthing different like this time khushi being a rich business girl like owning a fashion house or sumething who meets asr who is also the owner of a fashion house. first show how they hate each other and compete gain dominance over the other and then soon realise that they have fallen in love and the aftermath i suppose yu know better to write...
how abt khushi is the female version of ASR..and arnav is the male version of KKG...khushi can be rich and spolit ,sexy and flirty while ASR is a simple guy with high moral values...Khushi can be like Deepika in Cocktail...carefree and sexy while ASR is like SRK in JAb tak hai jaan...It would be fun to see role reversal...just a thought...
