Chand is not Abhays father
If you look at the early episodes where Haseena says to Chand what name are we going to come with this time....Chand says Raichands....Then Abhay comes along and says who am I....Chand says....you will be my son...my one and only millionaire son!!!!!!!.....When you look at the scenes between Chand and Abhay it is clear...there is no love between them....
