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 jealous of that feeling 
of not having room to breathe.
أغار من شعور عدم وجود مساحة للتنفّس هذا
Schade, dass ich mich
nicht entspannen kann.
Ojalá poder volver a sentir eso.
Invidio quella sensazione di pienezza.
Sinto falta dessa sensação
de não conseguir respirar direito.
Завидую её увлечённости.
