The Sabharwals did not love shaurya unconditionally....
It's confirmed that tej and devi can not have their own children
So the only eldest child is shaurya and that too a boy
If shaurya was really showered with love...he would have long forgotten astha..after all he was only 4-5 yrs old...he would be a happy child..
But only thing devi did was feed him with hatred against his mother...
I can never accept it as love
True love would have healed a little child long back...many children with traumatic past..if given the care..have grown up fine..i have seen such..
And most importantly...neither does he open up to them ..except hatred for astha..because that's the only thing Sabharwals listened and encouraged him with..
