Naho can't give her Valentine's Day chocolate to Kakeru. Ever since what happened on New Year's Eve, Kakeru keeps putting distance between Naho and himself. But, through all the hardships, Naho refuses to give up and fully intends to tell Kakeru how she feels. And so, the time comes for everyone to face the fateful day outlined in the letters from the past, "Kakeru's Final Day."
I won't let today be the last day.
.لن أدع اليوم يكون آخر يوم
Ich lasse nicht zu, dass
das heute dein letzter Tag wird.
No dejaré que este sea su último día.
No dejaré que este sea su último día.
Je ferai tout pour que 
ce ne soit pas ton dernier jour.
Farò in modo che oggi
non sia l'ultima volta che ci vediamo.
Não vou permitir que 
este seja o seu último dia.
Я не допущу, чтобы
это был последний день.
