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.
I'm sorry I always leave you 
on your own for Christmas Eve.
أنا آسف لترككِ دوماً بمفردكِ في عشيّة الكريسمس
Scusami se ti lascio sempre sola alla Vigilia...
Desculpa por sempre te deixar
sozinha na véspera de Natal.
Прости, что опять пропустил
канун Рождества.
