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.
She's the girl you were secretly talking 
to the day I got here late, isn't she?
إنّها نفس الفتاة الّتي كنتَ تتحدّث معها 
بشكل سرّيّ عندما تأخّرتُ يومها، صحيح؟
Ist das nicht auch die, mit der du heimlich
gesprochen hast, als ich zu spät kam?
Es con la que hablabas el otro día
cuando llegué tarde, ¿no?
Es con la que hablabas el otro día
cuando llegué tarde, ¿no?
Je suis sûre que tu étais avec elle
quand j’arrivais en retard !
Era la ragazza con cui stavi parlando di nascosto
il giorno in cui sono arrivata qui tardi, vero?
Foi com ela que você conversou em segredo
no dia em que cheguei tarde, não é?
Это с ней ты тайком общался в день,
когда я пришла позже обычного?
