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.

 just a misunderstanding.

Jetzt weiß ich, dass es
nur ein Missverständnis war.
Ahora sé que solo fue un malentendido.
Ahora sé que solo fue un malentendido.
Je sais

Ormai ho capito che

Agora sei que foi apenas
um mal-entendido.
Теперь я знаю,
что то было недоразумение.
