We are brought back in time to when Yume and Mizuto were once a couple. A time when neither of them could control their nerves in what was their first ever relationship. Having already held hands and kissed before, the young couple are eager to take the next step. Spring break passes, however, with neither able to make the first move. Upon entering their third and final year of middle school, the two are regrettably put into separate classes. Alas, unable to spend as much time together as before, they both begin to grow apart.
How could you do it where we've 
made so many memories together?!
كيف أمكنك فعل ذلك في المكان الّذي
!تجمعنا فيه عدّة ذكريات معًا؟
Warum hier, wo wir so viele gemeinsame
Erinnerungen gemacht haben?!
¡¿Cómo haces algo así donde
tenemos tantos recuerdos juntos?!
¡¿Cómo haces algo así donde
tenemos tantos recuerdos juntos?!
ici qu’on a plein de souvenirs !
Et toi, tu…
Come puoi fare una cosa simile nel posto
in cui abbiamo creato tanti ricordi insieme?!
Por que faz isso em um lugar
onde criamos tantas lembranças?
Почему здесь, где между нами
столько всего было?!
