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."
As long as you're happy, I'll be happy.
.إن كنتَ سعيدًا فأنا سعيدة
Solange du glücklich bist,
bin ich es auch.
Si tú eres feliz, yo también.
Si tú eres feliz, yo también.
Si tu l’es, je le serai aussi.
Se tu sei felice, lo sono anche io.
Estarei feliz se você estiver.
Я буду счастлива, пока счастлив ты.
