A Josei manga by Keiko Tobe. The story begins with Sachiko Azuma having her first child, Hikaru. He's not like the other babies, though: He stays in his stroller even when he's too old for it, he is only willing to eat the same thing every day, and he refuses to be held by his mother. Sachiko feels she is to blame...but she learns that Hikaru has autism -- a communication disorder. What ensues is the story of how Sachiko, her family, and others around them both hinder and contribute to Hikaru's life, and her ultimate goal that he will grow up to be "a cheerful working adult".
