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.
So there's no reason for you to suffer anymore.
.لذا ليس هنالك سببٌ لتتألّم بعد الآن
Also gibt es keinen Grund
mehr für dich, traurig zu sein.
Ya no tienes que sufrir más.
Ya no tienes que sufrir más.
Tu n’as donc plus besoin 
de te tourmenter autant.
Quindi non tormentarti più.
Você não precisa mais sofrer.
Тебе больше незачем так страдать.
