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."
And the painted-over future 
would return to its original form.
.والمستقبل المُغيّر سيعود إلى حالته الأصليّة
und die ausgetauschte Zukunft sollte
wohl wieder zur alten zurückspringen.
et le futur modifié 
redeviendra comme avant.
E il futuro che è stato riscritto
 tornerebbe al suo stato originario.
Não sabemos se o novo futuro 
também será substituído pelo antigo.
И переписанное будущее вернётся
к изначальному виду.
