A certain mother's story. Chisato Shoda, a mother of one, lives with her two children. And her son, Yasuhiro. Six months have passed since she divorced her husband. After her divorce, she was no longer swayed by her husband who was violently hedonistic and free-spirited. However, for his son, who was about to reach puberty, the change in the family environment seemed to have been a considerable shock, and he became a withdrawal. And when Chisato looks back on her son's current situation, she notices that as her son grows older, she has less and less to spoil him.
