TBH WHEN I SAW KAINAAT I FALL FOR HER SIMPLCITY however
THEN I SAW SALTANAT AND I LIKED HER MORE BECAUSE OF HER GOOD LOOKS AND BINDAAS. (sorry for caps letter not yelling lol) thats thing we all dont want to accept looks matter, we say we arent judgemental but we all are in some way.
EVEN ZAROON IS JUDGING, AND i bet he will have a change of heart too! HE WANTED TO A CHALLENGE AND HE WILL GET IT. It's Kainaat, she can be a major challenge for him. She is simple but her personality isnt its all layered.
