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.
Maybe nothing can be done 
to save my future self
ربما لا يوجد ما يمكن عمله لإنقاذ نفسي المستقبليّة
Ich kann mein zukünftiges
Ich vielleicht nicht
Quizás no pueda borrar
los arrepentimientos de mi yo futuro,
Quizás no pueda borrar
los arrepentimientos de mi yo futuro,
Sa tristesse et ses regrets,
Forse non potrò fare nulla 
per salvare la me stessa del futuro
Talvez eu não seja capaz de 
salvar a minha versão do futuro
И что ничто не избавит её
