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.
but since he hasn't spent a 
birthday at home in a while,
لكن بما أنّه لم يقضِ عيد ميلاد
،في المنزل منذ مدّة
Aber, jetzt wo er seit
Langem wieder hier ist …
pero seguro que lo celebra en casa
pero seguro que lo celebra en casa
ma è da tanto che non passa un compleanno a casa, 
quindi forse non dovrei disturbarlo...
já que faz tempo que ele não
passa o aniversário com a família,
но он только недавно приехал,
не хочу отрывать его в день рождения.
