Naho got into a fight with Kakeru on New Year's Eve, and never managed to apologize to him before he passed away. At least, that's what the letter from the future says. However, Naho now believes that she's capable of dealing with whatever may come up, and faces New Year's Eve head-on.
but it took a turn for the worse on Christmas Eve.
.ولكنّها ساءت في ليلة عيد الميلاد
Aber zu Heiligabend wurde
es plötzlich schlimmer.
mais ça a empiré 
le jour du réveillon.
ma il giorno della Vigilia si è aggravata di colpo.
Mas ela acabou piorando
 na véspera de Natal.
но в сочельник ей стало хуже.
