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 meets naturally, communicates, and shares life, rather than organizational interests such as school or work. Each person lives differently, but reminds him of the ‘beast realm’ (instinct) called motherhood, and makes him ponder the existence of a mother and a human being.
