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 way you don't cut them too short, 
and you can do careful maintenance.
بهذا الشكل لم تكوني تقصّيها كثيراً
ويمكنكِ العناية بها بحرص
Damit werden sie nie zu kurz,
Si no las cortas mucho,
puedes cuidarlas mejor.
Si no las cortas mucho,
puedes cuidarlas mejor.
C’est pratique, car ça permet
d’arranger comme on veut sans trop couper.
Così potevi curarle con precisione,
senza tagliare troppo.
Assim elas não ficam muito
curtas e dá pra manter o cuidado.
Если их не стричь под корень,
за ними проще следить.
