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.
My friends are having a party, 
so I'm going to pop in.
يقيم أصدقائي حفلة، لذا سأشاركهم قليلاً
Ein paar Freunde wollen feiern,
da schaue ich vorbei.
Iré a saludar a la fiesta de unos amigos.
Mis amigos dan una fiesta
y me voy a pasar.
Des amis font une fête,
je vais les rejoindre.
I miei amici sono andati a bere,
vado a fare una capatina.
Meus amigos vão fazer uma festinha,
então vou lá dar um oi.
Друзья устраивают гулянку —
хочу заглянуть к ним.
