In the original story though, the sister was an ally that offered her child for them to raise. I think it was to do with their God.
It was mentioned that a king was ordered to kill his sister, the then queen, from the Sun(?) God's order. I think it was implied that the God was maybe a women-hater, might have even communicated with the current king. Perhaps our MC was meant to be queen but the God interfered and the king "yielded." I don't know why else her father would say, "I yielded."
Omg he's completely mad??
