Hearing his tone Aanya don't know how to comfort him so only said,
"Papa, I understand but you don't have to be guilty about anything because you already give us everything"
"But…" Aditya opened his mouth,
"No Papa, what you did for me…...for us is enough, you are not... never obliged to do all the things you and mum did for us, it was never your responsibilities but you took us in and treated us as your own children and give us a love and everything that you gave your own children that is enough for us….. May be in this life we can't pay off the debt of yours Papa" Aanya said choking as she became emotional in this life may be she opening up is only in front of her father because he always there for her just like guardian angel
