Saras not being strong-> yes he took blame on himself -> that is why he is very kind and down to earth. He can't see other's pain.
He is not strong enough to stand himself...he was never able to see true color of Guman, he couldnt say No to his father re marraige.May be in future episode we will see him protecting Kumud and her family against Guman. For now he is not my perfect "Prince".
