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.
What are you talking about? 
We're the ones borrowing her.
عمّاذا تتكلّمين؟ نحن من نستعيرها
Was sagen Sie denn?
Wir leihen sie doch.
Ne dites pas ça !
C’est plutôt nous qui vous l’empruntons.
Ma cosa dice?
Siamo noi, semmai, ad avergliela rubata.
Do que você tá falando? Nós que
estamos pegando ela emprestada!
О чём вы говорите?
Это вы разрешили ей быть с нами.
