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 was still a high school student then.
.كنتُ ما أزال طالبةً في الثّانويّة حينها
Zu dieser Zeit
En aquel entonces,
aún iba a preparatoria
Por aquel entonces,
aún iba al instituto
À cette époque, 
j’étais encore lycéenne.
Al tempo, ero soltanto una ragazzina del liceo.
Naquele tempo, eu era apenas
 uma estudante de colegial
Я тогда была лишь школьницей.
