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."
Everything you've done for me is a treasure.
.كلّ شيءٍ فعلته لي هو كنز
Das, was du für mich
gemacht hast,
Todo lo que has hecho por mí
es un tesoro para mí.
Todo lo que has hecho por mí es un tesoro.
Tout ce que tu as pu faire 
pour moi est cher à mes yeux.
Tutto ciò che hai fatto per me, è un mio tesoro.
Todas as coisas que você fez
 por mim são o meu tesouro.
Я дорожу всем, что ты для меня сделал.
