Hanabi catches a cold, but both Iori and Konomi have to go to school, so Sonoa is left to take care of Hanabi. But Sonoa has some quirks to her personality, and things don't quite turn out as expected when she tries to take care of Hanabi.
I spent every day quiet, so that 
I wouldn't make any trouble.
Ich habe mich immer ruhig verhalten,
um keinen Ärger zu machen.
Intenté pasar toda la vida
sin llamar la atención.
Intenté pasar toda la vida
sin llamar la atención.
Je passais mes journées seule,
sans rien dire.
Me ne stavo sempre buona, 
per evitare di creare problemi.
Eu passava os dias quieta, assim
não causaria nenhum problema.
