Although Noguchi Satsuki has some communication problems with her son and husband, she feels great and watches them both work hard. Just like Ozawa Seiko, who has two children and a hard working husband. There is no connection between them, only the fact they two make a happy family -- that is what those two are thinking.But Satsuki's dear son, Tomoya, killed Kiyotaka, which is Seiko's little child. That is the point where both lives turn around. Why would such a little child kill?
Milyang is about a mother trying to overcome the loss of her child. Aishiteru is about the same thing, but involves two mothers and their families. They are both about the pain after losing a child, and what mothers (and their families) have to endure while trying to face the cruel reality of their loss. And the cruelest thing of all: that you have to continue living, even after that loss.
