The 'Green Mothers Club' captures the friendship, motherhood, and growth of five mothers who met in the elementary community, each with a complex that they could not overcome. It is a story that recounts the definition of a friend who meet naturally, communicate, and share life, rather than organizational interests such as school or work. Each person lives differently, but is reminded of the 'beast realm' (instinct) called motherhood, and ponders the existence of a mother and a human being.
