Kakeru gives Naho a hairpin. And on the weekend, Kakeru invites Naho to study with him for the upcoming exams. As the pair begin to grow closer together, Naho gets up the courage to invite Kakeru to see the fireworks together with her at the end of the school festival.
I can't erase the regrets of the future me!
!لا يمكنني مسح ندم نفسي المستقبليّة
Die Dinge,
die ich in der Zukunft bereue …
No puedo eliminar los arrepentimientos
de mi yo del futuro.
No puedo eliminar los arrepentimientos
de mi yo del futuro.
Je ne pourrai pas effacer 
ses regrets.
Non potrò in nessun modo
 cancellare i suoi rimpianti.
Então eu não sou capaz de acabar com os 
arrependimentos da minha versão do futuro.
Я не могу избавить
 будущую меня от сожалений!
