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.
That's right. I went around to Ryokushou, 
so I saw it. That big fir tree.
هذا صحيح. تجوّلتُ حول ريوكوشو فرأيتُ
تلك. شجرة التنّوب الكبيرة
Im Ryokusho habe ich
auch welche gelassen.
Ah, sí. Pasé por Ryokushou
y alcancé a verlo. El abeto.
Ah, sí. He pasado por Ryokushou
y lo he visto. El abeto.
Au fait, je suis passée à Ryokushô
Oh, giusto! 
Sono passata anche al Ryokusho,
Ah, verdade. Eu passei pelo Ryokushou
e vi aquela árvore gigante.
Ах да, в «Зелёной сосне» я тоже была
и видела вашу гигантскую ёлку!
