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 
children.
We'll be sharing a hotel
 room with them.
Compartiremos la habitación con ellas.
Vamos a compartir con ellas la misma habitación del hotel.
Nós vamos ficar no mesmo 
quarto de hotel que elas.
