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'll stay here with you 
until you fall asleep.
Ich bleibe bei dir,
bis du einschläfst.
J’attendrai que tu t’endormes.
Rimarrò con te finché non ti addormenterai.
Ficarei aqui com você até que durma.
