At dawn, the Azuma family welcomed their newborn son, Hikaru, whose name fittingly means "light." However, during a playdate, Hikaru's mother noticed that her child stood out from the other children. This heartbreaking but moving story follows a young mother as she learns to cope with the overwhelming realization that her child has autism and the difficulties that come with raising him while keeping her family together. It is a narrative that speaks not only to those who have been affected by autism but to all parents who face their own unique challenges.
Additionally, this volume features two one-shots: "Thank You Sensei!" and "Haru no Manazashi."
