It really doesn't matter if Jai hires or not. Jai is in totally in love with Bani and vice versa. No one can spoil their relation and no one can come between them whether they are together OR staying seperately. What kind of love is that if any tom dick and harry (Jigs / Pia / Ranveer / Roshini / Rnvijay etc etc)can break them apart - Hope Kasam Se doesn't become like Tumhari Disha in which all the time the lead roles fight, never stayed together (even though they love each other), always a third person comes between them and finally the lead role commits suicide - how stupid????
Anyway, Hope Kasam se doesn't follow that route and J&B get back together OR seperately fight against the evil BUT no third person between them.
