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.
Squee! The feel of his hand! 
I'll never forget it!
!هذا الإحساس بيده! لن أنساه ما حييت
¡Me dio la mano!
No me la voy a lavar nunca.
¡Me ha dado la mano!
No me la voy a lavar nunca.
Aaah! 
Non dimenticherò mai questa sensazione!
Ai, meu Deus! Eu senti a mão dele!
Nunca mais vou esquecer!
Мамочки! Ни за что не забуду
это ощущение!
