It's the last day of the school festival. Naho and Kakeru have promised to watch the fireworks together. However, just before they start, Ueda-sama gets in Naho's way. Will Naho get to experience watching the fireworks with Kakeru like her future self did?
But regret as I may, 
it's too late to change anything.
.ولكن حتّى لو ندمت، فإنّ الأوان قد فات لتغيير أي شيء
Aber für Reue
ist es nun zu spät.
Es demasiado tarde para arrepentirse.
Pero es demasiado tarde para arrepentirse.
J’ai beau le regretter, 
il est trop tard.
Ma ormai è troppo tardi per i rimpianti...
Mas agora, já é tarde demais,
 até mesmo para se lamentar.
Но уже ничего не изменишь.
