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."
Don't put off what you can't do to "tomorrow" or "someday." 
For Kakeru's sake, do anything you can do.
".لا تؤجّلي ما لا يمكنكِ فعله إلى "غدًا" أو "يومًا ما
.افعلي أيّ شيءٍ باستطاعتك من أجل كاكيرو
Verschiebe das, was du nicht kannst, nicht dauernd auf
„morgen“ oder „irgendwann“.
Mach alles für Kakeru, was in deiner Macht steht.
Haz todo lo que puedas por Kakeru.
Haz todo lo que puedas por Kakeru.
Fais tout ce que tu peux pour Kakeru.
Non rimandare a "domani" o "prima o poi",
ciò che non hai potuto fare. 

Fai qualsiasi cosa tu possa fare per Kakeru.
Faça o que você puder pelo Kakeru.
Не откладывай сложные задачи на «завтра» или «когда-нибудь». 
Сделай всё возможное ради Какэру.
