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.
I've heard that they decorate 
with real European firs overseas.
سمعتُ بأنّهم يزيّنون بأشجّار تنّوب 
أوروبّية حقيقيّة في بلاد الخارج
Im Ausland dekorieren
sie ja die Tannenbäume.
Dicen que en el extranjero
decoran abetos europeos.
He oído que en el extranjero
decoran abetos europeos.
All'estero decorano dei veri abeti europei,
Eu vejo muita gente falar que, fora do
Japão, decoram com árvores de verdade.
Говорят, в других странах
наряжают настоящие ели.
