Our father faces many difficulties and challenges to raise us, although we do not know it, because they do it without us seeing the difficulties that pass. This means that our father sacrifices himself so that we have no need and can live a full life, even if it hurts him. Accordingly, I believe that it is justifiable that, like Ko-Ngai, we sacrifice ourselves for our father, if necessary to keep him well. He would do the same for us.
