Since everyone is so busy opinionating themselves around here, I thought I'd offer my 'opinion' too.
I just can't stop raving about how adorable Karan and Surbhi are offscreen. They are almost as entertaining to watch as Asad and Zoya. What keeps me hooked to them is the special bond they share - the kind of friendship that is apparently frowned upon by many, but true and selfless nonetheless.
Here are a few instances that make me smile every time I watch them
1. The way he directed her hand towards her mouth, reminding her that there was a cake in her hand that she had to eat when she was busy reading fan letters.

2. The way they play around with each
S: Toh phone karke bata do mujhe!
K: Abhi next scene mein SMS karunga tumko!

3. He was the only one who celebrated her birthday grandly, making her feel at home even though she was shooting on her own birthday
4. The way she always respects him and his opinions, calling him 'aap'

5. He always helps her with her shots
K: Aise hi girna!

It's funny, I always wanted Karan to fall for Jenny when I watched DMG. Now that they're happily married, I catch myself wishing for QH to have happened to Karan before DMG. Oh well! A girl can always dream, right? Surbhi can be godmother to Karan's pretty babies.
And all you haters, the ones who think Surbhi is a desperate s**t who is trying to get laid by Karan or vice versa, please do feel free to post your 'opinions' here. You are only helping us increase our beloved forum's rankings!
