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.
Peaches and chestnuts take three years,
 but persimmons take eight.
الخوخ والكستناء يستغرقان ثلاث سنوات
بينما الكاكي يستغرق ثمانية
Ein Pfirsichbaum trägt nach
drei Jahren Früchte, die Kaki erst nach acht.
Hay árboles que tardan tres u ocho años,
pero el yuzu tarda nueve en dar frutos.
Hay frutas que tardan
tres u ocho años en madurar.
« Tout vient à point
à qui sait attendre. »
Se pesche e castagne vogliono tre anni
e i cachi otto,
Pêssegos e castanhas levam três anos,
mas caquis levam oito anos para dar frutos.
Персик и каштан выращивают три года, 
хурму — восемь, а юдзу — девять.
