One day, a mother with a baby visits Chiaki for vaccination. Haruna complains that Chiaki tries to strike the wrong vaccine because of a slight misstep. From that situation, Chiaki suspects that Haruna may have fallen into childcare neuroses. A few days later, Chiaki is called by Haruna. She tells her to beat a woman who works at a family restaurant. It seems that Haruna's husband is having an affair with the woman. Chiaki finds out that Haruna is being hunted down. "At that time, stop and check your feelings," Chiaki tells Haruna the words taught by her mother, Yuko. (Source: NHK)
