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.
Nagomu-san! After work, would you like 
to go see illumination displays with me?
ناغومو-سان! بعد دوام العمل، ما رأيك
بالذّهاب لرؤية عروض الإضاءة معي؟
Nagomu-san, wollen wir
nach der Arbeit vielleicht
Nagomu ! On pourrait aller voir
les illuminations, après le travail ?
Nagomu! Ti va se dopo il lavoro
Nagomu! Você gostaria de ir ver os
enfeites de natal comigo, depois do trabalho?
Нагому, не хотите сходить после работы
и посмотреть иллюминацию?
