While Mei was able to accept her feelings on Christmas night, for some reason Yuzu couldn't respond sincerely. Ever since then the two have barely exchanged words and their relationship only grows more awkward... More time passes until the school field trip draws near. On the day of the trip Yuzu oversleeps and dashes to the station, but she's too late to catch the train. While she's feeling depressed she runs into a pretty young girl, Tachibana Sara, who also missed her train.
Sometimes she's selfish, but she's 
a well-adjusted little sister.
Sie ist zwar manchmal ein bisschen egoistisch,
aber eine reife kleine Schwester.
A veces es egoísta,
pero es muy equilibrada.
A veces es egoísta,
pero es una chica equilibrada.
En plus, c’est une forte tête.
Ma soprattutto, è anche capricciosa.
Às vezes ela é egoísta, mas ela
é uma irmã bem-arrumada.
Она хорошая сестра,
хоть иногда и бывает своенравной.
