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.
I was certain we could never 
go back to the way things were.
تأكّدت أنّنا لا نستطيع العودة
.لسابق عهدنا مهما كان
war ich mir sicher, dass nichts mehr
so sein könnte wie früher.
sabía que nada
volvería a ser como antes.
sabía que nada
volvería a ser como antes.
je savais qu’on pourrait plus
faire marche arrière.
ero certo che le cose tra noi
non sarebbero mai più tornate come prima.
eu sabia que nada
voltaria a ser como era.
я был уверен,
что ничего не будет как раньше.
