For me its Zaroon Jamal and Asher
Zaroon- a representation of present generation guy. He looked breathtakingly handsome in every avatar of Zaroon whether it casuals, formals, traditional or night suits. It attitude was charming. He portrayed a collage boy, a bachelor executive , a possessive husband and a father. He was not a perfect man but what we liked about him was his imperfectly perfect character.
Jamal- a very responsible and experienced man. Has bitter experience like divorce but still finds good things in life. He is an optimistic man. An executive employee of a MNC. He is witty and very sensitive that makes him so lovable. He is nearly a perfect man.
Asher- He is shown as a perfect son, father and very responsible. Though he does not feel for Sara he is ready to accept her anger because he thinks he broke her heart. He marries someone against his wishes because he wants to fulfill the commitment of his father. He tries to be friends with Khirad because he was given her responsibility. He is an impossibly perfect man. What he did with Khirad was unacceptable. But viewers cannot hate him for that. At the end again he proved himself a perfect husband too. Persons like Asher hardly exists in this world.
Amog this three Asher is a fairy tale character whether Zaroon and Jamal a real character.
I like Wali and Hasan too. His films character Shrmad(KKL) and Vikram(Khubsoorat) was also good. Actually I like all FK characters.
