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?
There's no need to get caught up in 
whether the letter is right or wrong.
.لا حاجة للانهماك في ما إن كانت الرسالة على صوابٍ أم خطأ
Les choix de la lettre 
sont-ils justes ?
Non c'è alcun bisogno 
di perdersi in un mare di dubbi
Não devemos nos focar
 em ficar pensando
Верно в письме написано или нет...
Нечего на этом зацикливаться.
