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?

It's the athletic festival. Kakeru hurt his ankle during the pole-toppling game, and hid that fact from everyone else. Kakeru tries to keep his suffering to himself, when Suwa and the gang call out to him. Met with everybody's kindness, Kakeru begins to tell them what he's been keeping pent up inside. And then, the class relay begins.

Kakeru moves to Matsumoto with his mother mother after she decides to move there for her own reasons. When she passes away on the first day of school after Kakeru transfers, Kakeru blames himself and thus refuses Suwa's invitation to join the Soccer club. Kakeru sees some old classmates from Tokyo, but none of them understand what Kakeru is going through. In the end, Kakeru becomes so distressed that he feels that he has no way out.
