shravan is acting like a loser. is shravan ram's real son? i doubt

what is wrong with shravan? all day either he is in malhotra house or tiwari house doing nothing besides having fight with sumu or sitting like a looser. well sumu is not any better. actually they both are irritating now a days.i want nirmala to disappear ASAP.sometimes i wonder shravan is ramus real son or not. how could a father do this to his own son. he knows very well his son is suffering but nothing effecting him. shravan should not forgive his both parents ever. they don't deserve him. one thing i agree with ram today telling shravan be like a man. shravan needs to do that. why he stopped investigating aditya? this cvs never shows anything complete.
