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 often think, if I'd done this or that 
back then, would you still be alive?
كثيرًا ما أفكّر، إن فعلت هذا أو ذاك
 حينها، هل ستكون لا تزال حيًّا؟
Ich frage mich, ob du noch leben würdest,
wenn ich es so oder so gemacht hätte
No sé si seguirías vivo si hubiera hecho algo distinto, o si hice algo mal.
No sé si seguirías vivo si hubiera hecho algo distinto, o si hice algo mal.
Si nous avions agi différemment, 
tu serais peut-être en vie.
Mi chiedo spesso "E se quel giorno 
avessi agito diversamente, sarebbe ancora vivo?".
Se naquele momento eu tivesse agido de
 outra forma, talvez você estivesse vivo.
Я часто думал: сделай я так,
а не иначе, ты остался бы жив?
