The older students are off on a school trip leaving Akari and a needy Chinatsu alone.  Nadeshiko watches Himawari and Sakurako fight and remembers them as

You look as satisfied as my sister.
Te ves tan relajada como mi hermana.
Pareces tan relajada como mi hermanita...
Você parece tão feliz quanto a minha irmã.
