After IPK ended, I started watching QH, and then I felt "Oh wow, Gul has truly outdone herself." And I meant it, because now not only did she create a romantic saga with her usual interspersed comedic moments, but this time it was even more well-rounded, with her focus on all the other characters in the show as well. Honestly, like you said, I trust Gul and the CVs to give us only the best; I mean after all, QH is their baby. They wouldn't wanna destroy it themselves, so I'm sure whatever they have planned, whether it's a Zoya-Ayaan marriage track or not, it's still going to be worth the watch.
Besides, before starting on QH, most of us here had already read Zee's synopsis, so it's not like this is some serious super shock that we hadn't been expecting. QH is a lovely fictional show that we've all grown to love, let Gul and the CVs do the work/worrying, we should just sit back, relax and enjoy it (:
Oh and as a side note, all Gul said was that they wanted to cast someone who could be romantically paired with Zoya, she didn't say she was definitely going to do it or anything. The panic is seriously unwarranted. Let Gul do what she wants rather than put her in a corner and insist Asad and Zoya get together ASAP. We won't quite be left with a show to watch if everything wraps up so easily.
