It is all about what shaped their personality. IPK,QH,QH2... were kind of like that.
Maybe she will surprise us this time.
We have Aarzoo's story; Her father abandoned his family because he wanted a male heir. He married another female. Aarzoo matured before time and while her Mom wore the pants, she supported her. Now she wants to prove to the world and more importantly to her Dad that Females can do anything and she can take care of her family while BAF(being a female)
So aarzoo was
1. abandoned by a parent.
2. Had to shoulder responsibilities while other girls were dreaming about their prince charming.
Sahir?
Was he also abandoned by a parent? Or was just abandoned?
Did his father remarry ?And he saw his mom suffer? That he swore never to love and give that kind of pain to any female? Did his Dad remarry for money and that is why he said "Paisa hi Paise ko kheechta hai"?
That is why he never spends the 500 that Alvira gives him?
Usually in a four Lions show it's a one time only love, Ishq wala love...
So maybe a girl was not involved in his past? Or Maybe not...
Only time will tell...
Till then speculations Galore!!!!!!
