While cleaning her room, Himeno discovers a New Year's greeting card she got from Naoko when they were kids.
When she tries to get Naoko to explain the message on the card, somehow they end up going out to find Chinese bellflowers even though they're no longer in season?
so I stormed out and left a note 
saying I'd stay at Hime-chan's...
فغادرت وتركت ملاحظة بأنّي
سأبيت في منزل هيمي-تشان
und ihr beim Abhauen ’nen Zettel dagelassen,
dass ich bei dir unterkomme.
J’ai laissé un mot pour dire
que je fuguais chez toi.
e me ne sono andata lasciando un biglietto
con su scritto che avrei dormito a casa tua...
aí saí e deixei uma mensagem
dizendo que ficaria na sua casa...
и я умчалась, оставив весть,
что останусь у тебя.
