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.
And that just having someone to spend 
his birthday with made him happy.
ومجرّد وجود شخص يقضي عيد
ميلاده معه قد أسعده
Wenn jemand da ist,
mit dem ich den Tag verbringen kann,
Seguro que le alegra que alguien
le celebre su cumpleaños.
Que alguien lo celebre con él
seguro que lo hace muy feliz.
Tant qu’il a quelqu’un
pour l’accompagner, ça lui suffit.
È contento se ha qualcuno con cui passarlo.
Só de ter alguém pra passar o aniversário
dele com ele já deixava ele feliz.
И что всегда приятно,
когда есть с кем его отпраздновать.
