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.
I had no idea she was going to pass away.
.لم أتوقّع أنّها ستموت أبدًا
Hätte nie gedacht,
dass sie stirbt.
No creí que moriría.
No creí que moriría.
Je n’aurais jamais cru 
qu’elle me quitterait.
Non immaginavo che invece sarebbe morta.
Eu jamais imaginei que 
ela pudesse desaparecer.
И в мыслях не было, что она умрёт.
