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.
It passed before you came 
back home, Nagomu-san.
مضى قبل أن تعود للديار يا ناغومو-سان
Na, der war schon durch,
bevor du wieder gekommen bist.
Fue antes
de que volvieras a casa.
Fue antes
de que volvieras a casa, Nagomu.
Il est déjà passé.
Je l’ai fêté avant que tu reviennes ici.
Ma sì, è finito prima che tornassi tu.
Meu aniversário foi antes de
você ter voltado pra cá, Nagomu.
Он прошёл ещё до того,
как вы сюда приехали.
