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 can see you dwelling on it 
for the rest of your life.
أنت ستظلّ تجلب سيرة هذا الأمر طوال
 .حياتنا على أيّ حال
Kann mir denken, dass du
das ewig mit dir rumtragen wirst.
Tú sí te acordarás toda la vida.
Tú sí que te acordarás toda la vida.
T’es du genre rancunier.
Ti ci vedo, 
a tenertela legata al dito per la vita.
Parece que é você quem vai 
nos lembrar disso para sempre.
Это ты об этом всю жизнь думать будешь.
