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.
It's true we don't see each other much, 
but we became friends over the summer, right?
،صحيح بأنّنا لا نرى بعضنا الآخر كثيراً
لكن أصبحنا صديقتين في الصّيف، صحيح؟
Wir sehen uns wirklich kaum, aber
im Sommer haben wir uns angefreundet, ne?
Es cierto que no nos vemos mucho,
pero somos amigas desde el verano.
Es cierto que no nos vemos mucho,

C’est vrai,
mais on est devenues amies cet été.
È vero, non ci incontriamo,
ma siamo diventate amiche quest'estate.
É verdade que a gente não se vê tanto,
mas nós nos tornamos amigas no verão, não é?
Ты прав,
но мы подружились ещё летом.
