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?
I think it happened because 
he joined the soccer club.
.أعتقد أنّه حدث لأنّه انضم إلى نادي كرة القدم
Wahrscheinlich, weil ich Kakeru
in den Fußballklub geholt habe.
Probablemente porque Kakeru
se unió al club de fútbol.
Probablemente porque 
Kakeru se unió al club.
Sans doute parce que 
je l’ai fait rejoindre le club.
Probabilmente è una conseguenza
del fatto che Kakeru è entrato a far parte del club.
Acredito que isso só aconteceu porque
eu fiz ele entrar para o clube.
Думаю, это потому что Какэру
вступил в футбольную секцию.
