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.
Hurry up and get going. 
You'll run out of time.
اذهبا بسرعة. الوقت يُداهمكما
Geht schnell los. Die Zeit fliegt!
Deberían darse prisa.
El tiempo es oro.
Yo me iría ya o no tendréis tiempo.
Allez, file ! Le temps passe vite.
Sbrigatevi ad andare, il tempo corre!
Se apressa, se não vocês não vão ter
muito tempo pra passar juntas.
Идите скорее,
не тратьте времени зря.
