LOL Same is the case with me.
My sister used to see humsafar on youtube when it was on air and once she was watching it and I overheard a dialougue 'Badkismati se Iske Biological father aap hai'. I only heard that part n I burst out laughing I was like wat sort of a weird dialouge is dat. After dat I always used to make fun of my sis whenever I saw her watching the show :D but then I saw FK's picture in her laptop and I was like wow dis dude is good looking. Then I started taking interest in Paki actors n shows and somehow ended up watching Khuda aur mohabbat n not humsafar 1st. I was so bowled over by Imran dat I started watching all his other shows n realised that he was only good in Khuda aur mohabbat :D
Then Dastaan Happened and rest is history. <3
