This manga is definitely worth reading....you may call it old or the art is quite simple.
but the story and its message is quite strong and clear.
at this situation....this represents what humans are really made & yes.
no matter how educated you are or how far you will go....your animal instincts
always show when your life is between life and death.
and the Bonds between mother and child is always strong no matter where you go.
so that's why...ALWAYS CHERISH WHAT YOU HAVE....because someday it would be gone.
