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.
but starts to grow stronger 
again day by day.
لكن تزداد قوّتها ثانية يوماً بعد يوم
Ab dem Tag kehrt langsam
die Kraft der Sonne zurück.
reprend peu à peu
du poil de la bête à partir de là.
per poi tornare a splendere con tutte 
le sue forze a partire da quel giorno.
depois de passar esse dia,
sua força volta a se restaurar.
а после вновь начинает
набирать свою силу.
