Hi Aparna welcome to the forum, I agree with you that Jab love hua is a refreshing, funny, romantic show and different as well. The acting, dialogs, direction everything is good, even the title song and music. Didn't you watch some other serials by tony and deeya singh such as banegi apni baat and jassi jaisi koi nahi?
But I don't agree with you on the incident of sudeep and himani, I don't think Sudeep is rude or anything like that just because he refused to pose for a photograph doesn't mean that he is rude or arrogant and think too highly of himself, maybe he didn't want to pose for the photograph its his wish
