I think that abhir is sumhow connected 2 the gujral's. Maybe hes dad was the brother of aditya gujral aka ansh's adoptive father.
Cos abhir only really seems intrested in bhoomi an eku (personally i fink he only used bawri 2 get close 2 bhoomi), as seems desperate 2 marry bhoomi, an he used wotever influence he has 2 get eku out of jail.
An the only fing bhoomi an eku really have in common is that they r both ansh's children. So if abhir is connected 2 the gujral's then it makes sense 4 him 2 only care bout bhoomi an eku, an not the rest of the Viranis.
Plus he has major problem wit tulsi, an tulsi only. Is it cos she was the one who killed ansh?
