Haha wa Hatachi no Yume wo Miru

Overview

Ryosuke is increasingly alarmed by his mother's repeated careless mistakes. When Ryosuke returns home with his family for New Years, his mother asks him, "Who are these people?" Don't you remember……!? His mother who thinks she is still in her 20s. His father who is not willing to accept her condition. A son who leaves his wife and children to take care of his mother. A human drama that sharply and comically illuminates the state of a family dealing with dementia! (Source: Kodansha, translated)
