Up until now, Naho had been doing everything the letter from the future had told her to do, but is the letter always right? The letter from the future asks Naho to make sure Kakeru doesn't run the relay race at the athletic festival, but what does Naho decide to do?
Even if the letters can change the future,
،حتّى لو كان من الممكن أن يتغيّر المستقبل بسبب الرسالة
Auch wenn man mit dem Brief
die Zukunft verändert,
Aunque cambiemos el futuro gracias
a las cartas, no sabemos qué pasará.
Aunque cambiemos el futuro por
las cartas, no sabemos qué pasará.
Même en changeant l’avenir 
grâce à la lettre,
Potremo anche cambiare il futuro
grazie alle lettere,
Mesmo que consigamos mudar
 o futuro por causa da carta,
Даже если письма меняют будущее,
