Kakeru enters the soccer club as a provisional member, just as the letter says. When the topic of lunches comes up after practice, Kakeru jokingly asks Naho to make lunch for him as well. Naho finds herself bewildered by his words, but feels pushed to act by the letter from herself 10 years in the future, which tells Naho that she wishes she had made lunch for Kakeru.
Then I'll bring another one tomorrow!
!سأحضر واحدًا في الغد أيضًا إذًا
Dann bringe ich dir
morgen auch eine mit!
Mañana también te lo prepararé.
Mañana también te lo prepararé.
Alors, je t’en apporterai un 
demain.
Allora te ne farò un altro per domani!
Então vou preparar amanhã de novo!
Тогда я и завтра принесу!
