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."
Yeah. Let's make a world 
where Kakeru can smile forever.
.نعم. لنصنع عالمًا يبتسم فيه كاكيرو إلى الأبد
Ja, schaffen wir eine Welt,
in der Kakeru immer lacht.
Sí. Creemos un mundo
en el que siempre pueda sonreír.
Sí. Creemos un mundo
en el que siempre pueda sonreír.

Sì.
Sim! Vamos criar um mundo onde

Да. Создадим мир, где Какэру
сможет всегда улыбаться.
