A Mother's Song

Ryo's friend and Welfare Officer Keiko's mother is experiencing premature dementia, frustrating Keiko, especially since she still has bitter memories of her mother abandoning her as a child. Now her mother has suddenly wandered off with Keiko's daughter, and the search for them brings those old memories back once more. In the meantime, the other CSW workers try to persuade Eta-san from being taken in by a corrupt contractor.
