One day, with Christmas near, a message and a fir tree sent by Itsuka's mother arrive. Remembering back to the broken promises from when she was little, Itsuka is afraid to make another promise with her mother. But Nagomu's words give her a push, and she tells her mother that she'll be waiting.
Yuzu yokan causes Nagomu to remember a conversation he had with his grandfather.
Wow. I thought it was to 
keep from catching a cold.
ظننتُ أنّ فائدته هو الوقاية من نزلات البرد
Ach. Ich dachte,
dann erkälte ich mich nicht.
Vaya, yo pensaba
que evitaban que te resfriaras.
¡Hala! Yo pensaba
que evitaban que te resfriaras.
Oooh! Credevo servisse 
a non prendere il raffreddore!
Caramba. Achei que era só
pra não pegar resfriado.
Ух ты... А я думал,
это чтобы не простужаться.
