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.
On that day... Do you 
think Nagomu will be free?
في ذلك اليوم... هل تعتقدين بأنّ 
ناغومو سيكون متفرّغاً؟
M-Meinst du, dass Nagomu
an dem Tag Zeit hat?!
Ese día… ¿estará libre Nagomu?
¿Ese día… Nagomu va a estar libre?
Nagomu est libre, ce jour-là ?
chissà se quel giorno Nagomu è libero...
Você acha que... O Nagomu
vai estar livre nesse dia?
что Нагому в этот день свободен?
