What makes you say Gopi does not love Ahem. Their love story does not end just because of a little tiff. This is not even a tiff. She does not know about the bhang effecting his memory and he does not know about their tryst...there is no love lost...It is only love and nothing but love for each other. I think the reason they are only playing the male version is because they want to show how Ahem is wooing his wife and how much he loves her...
