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.
It was on New Year's Eve, wasn't it?
كان في ليلة السّنة الجديدة، أليس كذلك؟
Das war doch
sicher zu Silvester.
Fue la noche de Fin de Año.
Fue la noche de Fin de Año.
Si je me souviens bien, 
c’était au Nouvel An.
Mi pare sia stato all'ultimo dell'anno.
Se não me engano, você se
 declarou na virada do ano.
Кажется, в новогоднюю ночь, да?
