salar doesn't have much hatred for his parent ... he just doesn't like their approach and the fact that they don't support him in his passion - photography ... which exactly why Sitara told tahir to trust salar in terms of his professionalism ..
Tahir thinks that Salar doesn't behave properly with his parents and how he runs away every time something happens ... which exactly sitara is trying to make salar understand that how much his parents loves him and he should atleast not behave rudely with them ... that his parents will automatically realise how serious he is once he accomplished something ...

. If sitara still doesn't believe him, he will force sahiba to come and clear the misunderstanding to sitara
