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'd want him to be the happiest boy in the world.
.أريده أن يكون أسعد ولدٍ في العالم
Und ich würde mir wünschen,
dass er das glücklichste Kind der Welt wird.
Y que crezca para ser
el niño más feliz del mundo.
Y que crezca para ser
el niño más feliz del mundo.
Et qu’il soit l’enfant 
le plus heureux du monde.
E vorrei diventasse 
il bimbo più felice della Terra.
E fazer dele o garoto 
mais feliz do mundo!
Хотела, чтобы он был самым
счастливым мальчиком в мире.
