Insecurity of naman n karishma

Hi there ...first of all i dont understand the reason behind karishmas insecurity ...Naitik is the real son of rajbanna so he will be entititled to the business ...n he being the elder one he is bound to take responsibilities n make decisions ...naman is stepson but rajbanna never distinguished between him.n naitik ...so what if they r handling busines for 10 yrs ..they should be lucky that they got parents like rajbanna n bhabhimaa ...nahi toh now a days who gives step sons this much ...i dont like her taunting naman alwys abt business ...she should infact be thankful to naksh that they got importance for 10 yrs atleast nahi toh kaun puchtha tha unko ...
